The node server is connected to an access switch, which may be connected to a plurality of terminals and may be connected to an ethernet network.

The node server is a node which plays a centralized control function in the access network and can control the access switch and the terminal. The node server can be directly connected with the access switch or directly connected with the terminal.

2. Video networking packet definition

2.1 Access network packet definition

The data packet of the access network mainly comprises the following parts: destination Address (DA), Source Address (SA), reserved bytes, payload (pdu), CRC.

As shown in the following table, the data packet of the access network mainly includes the following parts:

DA

SA

Reserved

Payload

CRC

Wherein:

the Destination Address (DA) is composed of 8 bytes (byte), the first byte represents the type of the data packet (such as various protocol packets, multicast data packets, unicast data packets, etc.), there are 256 possibilities at most, the second byte to the sixth byte are metropolitan area network addresses, and the seventh byte and the eighth byte are access network addresses;

The Source Address (SA) is also composed of 8 bytes (byte), defined as the same as the Destination Address (DA);

The reserved byte consists of 2 bytes;

The payload part has different lengths according to different types of datagrams, and is 64 bytes if the datagram is various types of protocol packets, and is 32+1024 or 1056 bytes if the datagram is a unicast packet, of course, the length is not limited to the above 2 types;

The CRC consists of 4 bytes and is calculated in accordance with the standard ethernet CRC algorithm.

2.2 metropolitan area network packet definition

The topology of a metropolitan area network is a graph and there may be 2, or even more than 2, connections between two devices, i.e., there may be more than 2 connections between a node switch and a node server, a node switch and a node switch, and a node switch and a node server. However, the metro network address of the metro network device is unique, and in order to accurately describe the connection relationship between the metro network devices, parameters are introduced in the embodiment of the present invention: a label to uniquely describe a metropolitan area network device.

In this specification, the definition of the Label is similar to that of the Label of MPLS (Multi-Protocol Label Switch), and assuming that there are two connections between the device a and the device B, there are 2 labels for the packet from the device a to the device B, and 2 labels for the packet from the device B to the device a. The label is classified into an incoming label and an outgoing label, and assuming that the label (incoming label) of the packet entering the device a is 0x0000, the label (outgoing label) of the packet leaving the device a may become 0x 0001. The network access process of the metro network is a network access process under centralized control, that is, address allocation and label allocation of the metro network are both dominated by the metro server, and the node switch and the node server are both passively executed, which is different from label allocation of MPLS, and label allocation of MPLS is a result of mutual negotiation between the switch and the server.

as shown in the following table, the data packet of the metro network mainly includes the following parts:

DA

SA

Reserved

Label (R)

Payload

CRC

namely Destination Address (DA), Source Address (SA), Reserved byte (Reserved), tag, payload (pdu), CRC. The format of the tag may be defined by reference to the following: the tag is 32 bits with the upper 16 bits reserved and only the lower 16 bits used, and its position is between the reserved bytes and payload of the packet.

Specifically, the internet terminal may first obtain video directory information of a surveillance video stream stored in the internet video server, may then display the video directory information for selection by a user, may then generate a first obtaining request according to the selection of the user, where the first obtaining request is for the surveillance video stream stored in the internet video server, and may then send the first obtaining request based on the GB28181 protocol to the video network main server. The first obtaining request may also carry an identifier of the monitoring video stream selected by the user, and the like.

in the embodiment of the present invention, the first obtaining request may further carry a camera identifier of the monitoring camera, so as to indicate that the first obtaining request is used to obtain the monitoring video stream stored in the internet video server and acquired by the monitoring camera corresponding to the camera identifier.

In this embodiment of the present invention, the first obtaining request may further carry a source Address and a destination Address, where the source Address includes a terminal identifier of the Internet terminal, the terminal identifier may be an IP (Internet Protocol Address does not have GB28181 Protocol) Address of the Internet terminal, and the destination Address includes a server identifier of the Internet video server, and the server identifier may be an IP Address of the Internet video server.

In step S102, the video network master server receives the first obtaining request, converts the first obtaining request into a second obtaining request for obtaining the surveillance video stream based on the video network 8f85 protocol, and sends the second obtaining request to the video network sharing server;

In the embodiment of the invention, because the main video network server is not in direct communication connection with the internet video server, but the main video network server is in indirect communication connection with the internet video server through the video network sharing server and the video network coordination server, the main video network server needs to send data to the main internet server through the video network sharing server and the video network coordination server, however, because the main video network server is in communication connection with the video network sharing server based on the video network 8f85 protocol, after receiving the first acquisition request, the main video network server needs to convert the first acquisition request into a second acquisition request for acquiring the monitoring video stream based on the video network 8f85 protocol, and then sends the second acquisition request to the video network coordination server.

In step S103, the video network sharing server receives the second obtaining request, and sends the second obtaining request to the video network coordination server;

in the embodiment of the present invention, since the video sharing server is not in direct communication connection with the internet video server, but the video sharing server is in indirect communication connection with the internet video server via the video coordination server, the video sharing server needs to send data to the internet video server via the video coordination server, and since the video sharing server is in communication connection with the video coordination server based on the video 8f85 protocol, the video sharing server can directly send the second acquisition request to the video coordination server.

In step S104, the video-networking coordination server receives the second acquisition request, converts the second acquisition request into a first acquisition request based on the GB28181 protocol, and sends the first acquisition request to the internet video server;

in the embodiment of the present invention, since the video network protocol conversion server is directly connected to the internet video recording server through communication, the video network protocol conversion server may directly send data to the internet video recording server, however, since the video network protocol conversion server is connected to the internet video recording server through communication based on the GB28181 protocol, after receiving the second acquisition request, the video network protocol conversion server needs to convert the second acquisition request into the first acquisition request based on the GB28181 protocol, and then send the first acquisition request to the internet video recording server, for example, send the first acquisition request to the internet video recording server according to the destination address carried by the first acquisition request.

in step S105, the internet video server receives the first obtaining request, obtains a first surveillance video stream based on the GB28181 protocol, where the first surveillance video stream is obtained according to the surveillance video stream stored in the internet video server or the first surveillance video stream includes the surveillance video stream stored in the internet video server, and sends the first surveillance video stream to the video networking coordination server;

In the embodiment of the invention, the internet video recording server can send the first monitoring video stream to the internet terminal through the video network.

However, the main server of the video network is used for receiving external instructions based on the GB28181 protocol and sending the instructions based on the GB28181 protocol to the outside, however, the main server of the video network is not used for receiving external entity data streams based on the GB28181 protocol, such as video streams, audio streams, picture streams, and text streams, and is not used for sending entity data streams based on the GB28181 protocol to the outside.

The video network sharing server can be used for receiving an external entity data stream based on the GB28181 protocol and sending the entity data stream based on the GB28181 protocol to the outside.

therefore, the internet video server can transmit the first monitoring video stream to the internet terminal through the video network coordination server and the video network sharing server which are positioned in the video network.

the first surveillance video stream includes a surveillance video stream stored in the internet video server, and may also have a source address and a destination address, where the source address includes a server identifier of the internet video server, and the server identifier may be an IP address of the internet video server, or the like. The destination address comprises a terminal identifier of the internet terminal, and the terminal identifier can be an IP address of the internet terminal and the like.

In the embodiment of the present invention, if the first acquisition request further carries a camera identifier of the surveillance camera, the second acquisition request will carry the camera identifier of the surveillance camera, so that when the internet video server acquires the surveillance video stream according to the second acquisition request, the internet video server can acquire the surveillance video stream stored in the internet video server and acquired by the surveillance camera corresponding to the camera identifier, for example, in a third correspondence between the camera identifier of the surveillance camera and the surveillance video stream acquired by the surveillance camera, search for the surveillance video stream corresponding to the camera identifier, generate a first surveillance video stream based on a GB28181 protocol according to the acquired surveillance video stream, and then send the first surveillance video stream to the video networking coordination server.

in the embodiment of the present invention, the supported protocol of the first surveillance video stream is different from the supported protocol of the second surveillance video stream, but the information content in the first surveillance video stream is the same as the content in the second surveillance video stream.

in step S106, the video networking coordination server receives the first surveillance video stream, converts the first surveillance video stream into a second surveillance video stream based on the video networking 8f85 protocol, and sends the second surveillance video stream to the video networking sharing server;

In the embodiment of the present invention, since the video networking protocol conversion server is not in direct communication connection with the internet terminal, but the video networking protocol conversion server is in indirect communication connection with the internet video recording server via the video networking shared server, the video networking protocol conversion server needs to send data to the internet terminal via the video networking shared server, however, since the video networking protocol conversion server is in communication connection with the video networking shared server based on the video networking 8f85 protocol, after receiving the first surveillance video stream, the video networking protocol conversion server needs to convert the first surveillance video stream into the second surveillance video stream based on the video networking 8f85 protocol, and then send the second surveillance video stream to the video networking shared server.

In step S107, the video networking sharing server receives the second surveillance video stream, converts the second surveillance video stream into a first surveillance video stream based on the GB28181 protocol, and sends the first surveillance video stream to the internet terminal;

In the embodiment of the present invention, since the video sharing server is in direct communication connection with the internet terminal, the video sharing server may directly send data to the internet terminal, however, since the video sharing server is in communication connection with the internet terminal based on the GB28181 protocol, after receiving the second surveillance video stream, the video sharing server needs to convert the second surveillance video stream into the first surveillance video stream based on the GB28181 protocol, and then send the first surveillance video stream to the internet terminal; for example, the first surveillance video stream is sent to the internet terminal according to the destination address carried by the first surveillance video stream.

further, the internet terminal can also receive the first monitoring video stream, store the first video network monitoring video stream and/or play the first monitoring video stream.

In another embodiment of the present invention, when the first surveillance video stream is stored, the internet terminal may compress the first surveillance video stream to obtain a compressed surveillance video stream, and then store the compressed surveillance video stream, where the space occupied by the compressed surveillance video stream is smaller than the space occupied by the first surveillance video stream, so that, compared with directly storing the first surveillance video stream in the internet terminal, storing the compressed surveillance video stream in the internet terminal may save the storage space of the internet terminal.

the embodiment of the present invention does not limit the specific compression method.

in the embodiment of the invention, in order to save network resources, the first monitoring video stream is obtained by compressing the monitoring video stream stored in the internet video server; the space occupied by the first surveillance video stream is smaller than the space occupied by the surveillance video stream stored in the internet video server.

Therefore, when the internet terminal plays the first monitoring video stream, the first monitoring video stream can be decompressed to obtain the monitoring video stream stored in the internet video server, and then the monitoring video stream stored in the internet video server is played.

If the first monitoring video stream is directly stored in the internet terminal, anyone can play the first monitoring video stream in the internet terminal and cannot view the first monitoring video stream, so that the information safety cannot be guaranteed.

therefore, in order to ensure information security, in another embodiment of the present invention, when storing the first surveillance video stream, the internet terminal may encrypt the first surveillance video stream to obtain an encrypted surveillance video stream, and then store the encrypted surveillance video stream.

Others cannot decrypt the encrypted surveillance video stream,

compared with the method that the first monitoring video stream is directly stored in the internet terminal, the information safety can be guaranteed by storing the encrypted monitoring video stream in the internet terminal.

The embodiment of the present invention does not limit the specific encryption method.

In the embodiment of the invention, in order to ensure information security, the first monitoring video stream is obtained by encrypting the monitoring video stream stored in the internet video server, so that when the internet terminal plays the first monitoring video stream, the first monitoring video stream can be decrypted to obtain the monitoring video stream stored in the internet video server, and then the internet terminal plays the monitoring video stream stored in the internet video server.

Others cannot decrypt the encrypted surveillance video stream,

correspondingly, when the owner of the internet terminal needs to play the first monitoring video stream later, the encrypted monitoring video stream can be decrypted to obtain the first monitoring video stream, and then the first monitoring video stream is played.

If the internet video server can be accessed by any terminal, the information security of the internet video server cannot be guaranteed.

therefore, in order to ensure the information security of the internet video server, when a certain terminal needs to access the internet video server, an access request needs to be made to the internet video server, if the internet video server allows the device to access the internet video server, the internet video server issues an access token to the terminal, and then when the terminal accesses the internet video server, the terminal needs to use at least the access token to access the internet video server.

Thus, in the embodiment of the present invention, the first acquisition request further carries the terminal identifier of the internet terminal and the access token for accessing the internet video server, that is, the second acquisition request further carries the terminal identifier of the internet terminal and the access token for accessing the internet video server, where the access token is allocated to the internet terminal by the internet video server in advance;

In this way, after the internet video server receives the second acquisition request, the terminal identifier and the access token can be extracted from the second acquisition request; detecting whether the access token is valid according to the terminal identification; if the access token is valid, the Internet video recording server acquires the first monitoring video stream based on the GB28181 protocol again, and sends the first monitoring video stream to the video network coordination server again.

in another embodiment, if the access token is invalid, the internet video recording server may generate a first access denial prompt based on the GB28181 protocol, where the first access denial prompt is used to indicate that the internet terminal corresponding to the terminal identifier does not have access right to the internet video recording server, and send the first access denial prompt to the video network coordination server;

The video networking main server receives the second access denial prompt, converts the second access denial prompt into a first access denial prompt based on a GB28181 protocol, and sends the first access denial prompt to the Internet terminal;

and the Internet terminal receives the first access denial prompt and displays the first access denial prompt. Therefore, a user using the Internet terminal can access the Internet video server only after knowing that the user does not have the access authority to the Internet video server and applying for the access authority to the Internet video server.

In the embodiment of the invention, each time the internet video server issues an access token to a terminal, the terminal identifier of the terminal and the issued access token form a corresponding table item, and the corresponding table item is stored in the first corresponding relation between the stored terminal identifier of the terminal and the access token distributed for the terminal.

therefore, when the internet video server detects whether the access token is valid according to the terminal identifier, whether a corresponding table item comprising the terminal identifier of the internet terminal and the access token carried by the second acquisition request exists or not can be searched in the first corresponding relation between the stored terminal identifier of the terminal and the access token distributed for the terminal; if the corresponding table item comprising the terminal identifier of the Internet terminal and the access token carried by the second acquisition request exists, the Internet video server determines that the access token is valid; and if the corresponding table item comprising the terminal identifier of the Internet terminal and the access token carried by the second acquisition request does not exist, the Internet video server determines that the access token is invalid.

In the embodiment of the invention, each access token issued by the internet video server has a valid period, for example, 5 minutes, 1 hour or 24 hours, and the like, if the access token is in the valid period, the access token can be used for accessing the internet video server, and if the access token is invalid, the access token cannot be used for accessing the internet video server.

therefore, in order to further guarantee the information security of the internet video server, the internet video server may detect whether the aging of the access token expires, wherein the detection may be performed periodically or in real time, and if the aging of the access token expires, the internet video server may delete the corresponding entry from the first corresponding relationship. And then the access token with the expired time period cannot be used for accessing the Internet video recording server, and a new access token needs to be applied again.

Alternatively, in another embodiment, the internet video server, after issuing an access token to a terminal that has accessed the internet video server using the access token, but has not accessed the internet video server again using the access token for a long period of time thereafter, may be that the device no longer has a need to access the internet video server, i.e., may not continue to access the internet video server thereafter. In this case, if the corresponding entry between the device identifier of the device and the access token is always stored in the first corresponding relationship, the storage space of the internet video recording server is wasted.

Therefore, in another embodiment of the present invention, the internet video server may obtain a search time when searching the corresponding table entry in the first corresponding relationship; and then, in a second corresponding relation between the access token and the latest searching time of the access token, replacing the latest query time corresponding to the access token in the corresponding table item by using the obtained searching time.

Then, the Internet video server can detect whether the duration of the access token which is not searched is longer than the preset duration or not according to the latest query time after replacement in real time; if the access token is longer than the preset time, the access token may not be used any more, or the internet terminal may not have a requirement for accessing the internet video server any more in a short time, so that the corresponding table entry including the access token may be deleted from the first corresponding relationship, thereby saving the storage space of the internet video server.

In one embodiment, the video network main server and the video network protocol conversion server can also be connected based on the video network 8f85 protocol communication.

Before the internet terminal acquires the monitoring video stream from the internet video server, directory information of the monitoring video stored in the internet video server may be acquired first, and then the monitoring video stream to be acquired may be determined according to the directory information.

For example, referring to fig. 7, a flowchart illustrating steps of a method for acquiring video directory information based on a video network according to an embodiment of the present invention is shown, where the method may specifically include the following steps:

In step S201, the internet terminal sends a first obtaining request based on the GB28181 protocol to the video network main server, where the first obtaining request is used to obtain directory information of a monitoring video stored in the internet video server;

In the embodiment of the invention, the internet video server is in communication connection with the plurality of cameras, each camera is used for collecting monitoring videos and uploading the collected monitoring videos to the internet video server, and the internet video server can store the monitoring videos uploaded by each monitoring camera.

Then, when the user needs to check the monitoring video, the directory information of the monitoring video stored in the internet video server can be obtained first, then the monitoring video needing to be checked is determined according to the directory information, and then the monitoring video needing to be checked is obtained from the internet video server.

The directory information includes an identifier of a camera communicatively connected to the internet video server, a location of each camera, an administrative organization to which each camera belongs, and a working time of each camera, which is not limited in this embodiment of the present invention.

The internet terminal may obtain the directory information of the monitoring videos stored in the internet video server through the video network, for example, the directory information of the monitoring videos stored in the internet video server is obtained through a video network main server and a video network coordination server located in the video network.

Specifically, the internet terminal may generate a first acquisition request for acquiring directory information of a surveillance video stored in the internet video server, and may then transmit the first acquisition request based on the GB28181 protocol to the video network main server.

In step S202, the video network master server receives the first obtaining request, converts the first obtaining request into a second obtaining request for obtaining the directory information based on the video network 8f85 protocol, and sends the second obtaining request to the video network coordination server;

In the embodiment of the present invention, since the main video network server is not in direct communication connection with the internet video server, but the main video network server is in indirect communication connection with the internet video server via the video network protocol conversion server, the main video network server needs to send data to the internet video server via the video network protocol conversion server, however, since the main video network server is in communication connection with the video network protocol conversion server based on the video network 8f85 protocol, after receiving the first obtaining request, the main video network server needs to convert the first obtaining request into a second obtaining request for obtaining the directory information based on the video network 8f85 protocol, and then send the second obtaining request to the video network protocol conversion server.

in step S203, the video-on-internet protocol conversion server receives the second acquisition request, converts the second acquisition request into a first acquisition request based on the GB28181 protocol, and sends the first acquisition request to the internet video recording server;

In the embodiment of the present invention, since the video network protocol conversion server is directly connected to the internet video recording server through communication, the video network protocol conversion server may directly send data to the internet video recording server, however, since the video network protocol conversion server is connected to the internet video recording server through communication based on the GB28181 protocol, after receiving the second acquisition request, the video network protocol conversion server needs to convert the second acquisition request into the first acquisition request based on the GB28181 protocol, and then send the first acquisition request to the internet video recording server. For example, the first acquisition request is sent to an internet video recording server according to a destination address carried by the first acquisition request.

In step S204, the internet video server receives the first obtaining request, obtains first video directory information based on the GB28181 protocol, where the first video directory information includes directory information of the monitoring video stored in the internet video server, and sends the first video directory information to the video networking coordination server;

the internet video server may send the first video directory information to the internet terminal through the video network, for example, send the first video directory information to the internet terminal through a video network coordination server and a video network main server located in the video network.

The first video directory information includes directory information of the monitoring video stored in the internet video server, and of course, the first video directory information may also include a source address and a destination address, the source address includes a server identifier of the internet video server, and the server identifier may be an IP address of the internet video server, and the like. The destination address comprises a terminal identifier of the internet terminal, and the terminal identifier can be an IP address of the internet terminal and the like.

In step S205, the video network protocol conversion server receives the first video directory information, converts the first video directory information into second video directory information based on the video network 8f85 protocol, and sends the second video directory information to the video network main server;

In the embodiment of the present invention, since the video network protocol conversion server is not in direct communication connection with the internet terminal, but the video network protocol conversion server is in indirect communication connection with the internet terminal via the video network main server, the video network protocol conversion server needs to send data to the internet terminal via the video network main server, however, since the video network protocol conversion server is in communication connection with the video network main server based on the video network 8f85 protocol, the video network protocol conversion server needs to convert the first video directory information into the second video directory information based on the video network 8f85 protocol after receiving the first video directory information, and then send the second video directory information to the video network main server.

in the embodiment of the invention, the protocol supported by the first video directory information is different from the protocol supported by the second video directory information, but the information content in the first video directory information is the same as the content in the second video directory information.

In step S206, the video networking host server receives the second video directory information, converts the second video directory information into the first video directory information based on the GB28181 protocol, and sends the first video directory information to the internet terminal;

In the embodiment of the invention, because the video network main server is in direct communication connection with the internet terminal, the video network main server can directly send data to the internet terminal, however, because the video network main server is in communication connection with the internet terminal based on the GB28181 protocol, after receiving the second video directory information, the video network main server needs to convert the second video directory information into the first video directory information based on the GB28181 protocol, and then sends the first video directory information to the internet terminal; for example, the first video directory information is sent to the internet terminal according to the destination address carried by the first video directory information.

further, the internet terminal receives the first video directory information.

further, in order to enable the user to view the first video directory information, the internet terminal may also display the first video directory information, for example, on a screen.

Further, in order to facilitate the user to view the first video directory information in the internet later, the internet terminal may further store the first video directory information, for example, locally at the internet terminal. And then, when the user needs to check the directory information of the monitoring videos stored in the internet video server again, the internet terminal can directly acquire the first video directory information stored locally without repeatedly executing the process to acquire the first video directory information, so that the efficiency of acquiring the first video directory information can be improved.

compared with the method that the directory information of the monitoring videos stored in the internet video server can be obtained from the internet video server only through the internet, in the embodiment of the invention, the internet terminal obtains the directory information of the monitoring videos stored in the internet video server from the internet video server through the video network main server and the video network cooperative server, so that the directory information of the monitoring videos stored in the internet video server in the video network can be obtained, and the obtaining way of obtaining the directory information of the monitoring videos stored in the internet video server is expanded. And because the video network is a private network, compared with the method for obtaining the monitoring video through the Internet, the embodiment of the invention can improve the information security through the directory information of the monitoring video stored in the video network Internet video server.
