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.

Similarly, devices of the metropolitan network portion may also be classified into 3 types: a metropolitan area server, a node switch and a node server. The metro server is connected to a node switch, which may be connected to a plurality of node servers.

The node server is a node server of the access network part, namely the node server belongs to both the access network part and the metropolitan area network part.

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

Therefore, the whole video network is a network structure with layered centralized control, and the network controlled by the node server and the metropolitan area server can be in various structures such as tree, star and ring.

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.

Based on the above characteristics of the video network, one of the core concepts of the embodiments of the present invention is provided, and the embodiments of the present invention may be applied to the video network, where a data storage instruction in a network disk client is first received, where the data storage instruction is used to instruct to store internet data to be stored to a network disk server, then the internet data to be stored is converted into video network data to be stored according to the data storage instruction, and the video network data to be stored is transmitted to the network disk server in the video network, and the video network data to be stored is stored by the network disk server. Therefore, because the existing network disk is transmitted through the Internet, the real-time performance of data transmission is poor, the invention converts the Internet data to be stored into the data of the video network, thereby storing the data at the network disk server side in the video network, improving the real-time performance of data storage and improving the efficiency of data transmission.

Referring to fig. 5, a flowchart illustrating steps of an embodiment of a data storage method based on a video network according to the present invention is shown, where the method may be applied to a video network, and specifically may include the following steps:

step 501: and receiving a data storage instruction in the network disk client.

The data storage instruction is used for indicating that the internet data to be stored is stored to a network disk server in the video network.

In the embodiment of the present invention, a user may perform user registration in a network disk client, and after the registration is completed, the user may log in through a registration account and a registration password, so that the user may check file data of the user in the network disk client, and in addition, the user may perform data processing operations (such as data storage, data acquisition, data movement, renaming of a file where the data is located, creating a folder, collecting data, sharing data, deleting data, and the like) after logging in the network disk client, the network disk client may generate a corresponding data processing instruction according to the data processing operations, it needs to be noted that when the user performs user registration, login, or data processing operations in the network disk client, the network disk server generates a corresponding processing result, and displays the processing result to the user in the network disk client, for example, if the user deletes a certain file data in the network disk client, the network disk client no longer displays the certain file data after the network disk server deletes the certain file data.

In this step, the user may perform a data storage operation in the network disk client, for example, the data storage operation may include dragging file data into the network disk client, or clicking a data upload button in the network disk client, so that the network disk client may display a to-be-selected file data list to the user, so that the user may select the to-be-stored internet data from the to-be-selected file data list, and complete selection of the to-be-stored internet data after the user clicks a confirmation button. In addition, the present invention may perform data storage operation on a plurality of internet data to be stored, for example, by clicking a data upload button in the network disk client, and when the network disk client displays the file data list to be selected to the user, the user may select the plurality of internet data to be stored from the file data list to be selected, and click a confirmation button, which is only an example, and the present invention is not limited thereto.

Step 502: and carrying out protocol conversion on the internet data to be stored according to the data storage instruction to obtain the video networking data to be stored.

Because the internet data and the video data are different, in order to enable the internet data to be transmitted in the video network, a data protocol converter may be adopted in this step, and the internet data to be stored is converted into the video network data to be stored according to the data storage instruction, where the data protocol converter may be a storage gateway, and the above example is only an example, and the present invention is not limited thereto.

Step 503: and transmitting the video networking data to be stored to a network disk server, and storing the video networking data to be stored through the network disk server.

In the embodiment of the invention, the characteristic that the video network has high-speed transmission is considered, and the data transmission between the network disk client and the network disk server depends on the video network, so that the data processing efficiency is improved. For the large-capacity data, if the large-capacity data has data transmission errors, the large-capacity data needs to be retransmitted, in order to solve the problem, when the video network data to be stored is transmitted to the network disk server, the large-capacity data can be subjected to fragmentation processing to obtain a plurality of pieces of data so as to sequentially perform data processing on the plurality of pieces of data, so that if part of the data fails to be transmitted, the part of the data can be retransmitted. In addition, after receiving the multiple pieces of data, the network disk server may perform fragmented data storage, and of course, may also perform merging and storage on the multiple pieces of data, for example, the network disk server in the present invention supports large data storage with a capacity exceeding 4GB and high-rate data transmission, and the above example is only an example, and the present disclosure does not limit this.

As can be seen from the above, the network disk server in the present invention can receive data sent by a network disk client in the internet, where the data protocol converter preferentially communicates with the network disk client through an internet protocol to obtain the internet data to be stored, the internet protocol may include a tcp (transmission Control protocol) protocol or a udp (user data protocol) protocol, and the like, then the data protocol converter converts the internet data to be stored into the video networking data to be stored, and finally the data protocol converter transmits the video networking data to be stored to the network disk server by using the video networking protocol. In another embodiment of the present invention, the network disk server may further receive data sent by the network disk client in the video network, and at this time, the data sent by the network disk client in the video network is transmitted to the network disk server through the video network protocol without protocol conversion in step 502.

It should be noted that, in order to ensure the security of data transmission, the present invention may also perform encryption processing on the video networking data to be stored, so that other users cannot view the video networking data to be stored after acquiring the video networking data to be stored.

In summary, a data storage instruction in the network disk client is received, where the data storage instruction is used to instruct to store the internet data to be stored to the network disk server, and then the internet data to be stored is converted into the video networking data to be stored according to the data storage instruction, and the video networking data to be stored is transmitted to the network disk server in the video networking, and the video networking data to be stored is stored through the network disk server. Therefore, because the existing network disk is transmitted through the Internet, the real-time performance of data transmission is poor, the invention converts the Internet data to be stored into the data of the video network, thereby storing the data at the network disk server side in the video network, improving the real-time performance of data storage and improving the efficiency of data transmission.

Referring to fig. 6, a flowchart illustrating specific steps of an embodiment of a data storage method based on a video network according to the present invention is shown, where the method may be applied to a video network, and specifically may include the following steps:

step 601: and receiving a data storage instruction in the network disk client.

Step 602: and carrying out protocol conversion on the internet data to be stored according to the data storage instruction to obtain the video networking data to be stored.

In this step, a data protocol converter is adopted to perform protocol conversion on the internet data to be stored according to the data storage instruction to obtain the video networking data to be stored. The data protocol converter may obtain the to-be-stored internet data by using an internet protocol.

Step 603: and transmitting the video networking data to be stored to a network disk server, and storing the video networking data to be stored through the network disk server.

In the embodiment of the invention, the video networking data to be stored can be transmitted to the network disk server by adopting a video networking protocol.

It should be noted that, the network disk server stores the network disk data, at this time, the network disk client may send the corresponding network disk data to the network disk client according to a data acquisition instruction of the user in the network disk client, and the specific process refers to the following steps:

step 604: and receiving a data acquisition instruction in the network disk client.

The data acquisition instruction is used for indicating that the video network data to be acquired is acquired from the network disk server.

In this step, the user may perform a data obtaining operation on the to-be-obtained video networking data in the network disk client, for example, the data obtaining operation may be a double-click operation on a data identifier of the to-be-obtained video networking data, or select the to-be-obtained video networking data, and click an obtaining button, or the like.

Step 605: and acquiring the video networking data to be acquired from the network disk server according to the data acquisition instruction.

In the embodiment of the present invention, the data obtaining instruction may include a data identifier of the video network data to be obtained, so that the network disk server may obtain the video network data to be obtained from the network disk data according to the data identifier.

In addition, when the to-be-acquired video networking data is media data, considering that the network disk server can store media data of different formats, but the terminal where the network disk client is located does not support the playing of the media data of each format, or the playing effects of the media data of different formats are different, in order to improve the use experience of a user, in this step, if the to-be-acquired video networking data is media data, the data acquisition instruction may include the playing performance parameters of the terminal where the network disk client is located (such as the bandwidth of the network used by the terminal, the processing capability of the terminal, a player installed in the terminal, and the like), so that the data protocol converter may send the data acquisition instruction to the network disk server, and the network disk server may transcode the media data into the format of the optimal playing of the terminal where the network disk client is located according to the data acquisition instruction, so that the data protocol converter can acquire the transcoded media data from the network disk server. For example, the video data may be in a ts format, a flv format, an avi format, an mp4 format, and if the video network data to be acquired in the network disk server is ts video data, and the terminal where the network disk client is located supports flv video data, at this time, the ts video data may be converted into flv video data by the network disk server, and the converted flv video data is transmitted to the data protocol converter, so that the data protocol converter performs protocol conversion on the flv video data.

Step 606: and carrying out protocol conversion on the video networking data to be acquired to obtain the Internet data to be acquired.

Similarly, the data protocol converter is adopted to convert the to-be-acquired video network data into to-be-acquired internet data.

The network disk client in the invention can be a client in the internet, at this time, the network disk server can acquire the data of the video network to be acquired and transmit the data of the video network to be acquired to the data protocol converter through the video network protocol, the data protocol converter converts the video network to be acquired into the data of the internet to be acquired and transmits the data of the internet to be acquired to the network disk client through the internet protocol; of course, the network disk client in the invention can also be a client in the video network, so that the invention does not need a data protocol converter to carry out data protocol conversion, and the network disk server can directly send the video network data to be acquired to the network disk client.

Step 607: and sending the to-be-acquired internet data to the network disk client.

It should be noted that, for simplicity of description, the method embodiments are described as a series of acts or combination of acts, but those skilled in the art will recognize that the present invention is not limited by the illustrated order of acts, as some steps may occur in other orders or concurrently in accordance with the embodiments of the present invention. Further, those skilled in the art will appreciate that the embodiments described in the specification are presently preferred and that no particular act is required to implement the invention.
