In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic diagram of a DHT network architecture according to the disclosure. As shown in fig. 1, the DHT (Distributed Hash Table) network architecture includes a server, a plurality of external network nodes, a router, and a plurality of internal network nodes. It should be noted that the number of the extranet nodes and the intranet nodes shown in fig. 1 is only an example, and the DHT network architecture may include more or less extranet nodes and intranet nodes than those shown in fig. 1, and the present invention is not limited thereto. Wherein, the extranet node and the intranet node both belong to network nodes in a DHT network architecture.
The server is a computer system capable of providing services to other devices (such as an extranet node and an intranet node) in a network. The server stores some information of the external network nodes, such as node identification ID, IP address and port, whether the external network nodes are external network nodes, etc. When a new node needs to join the DHT network, the new node can access the server to acquire some information of the external network nodes, then communicates with the external network nodes according to the information, and then does not need to communicate with the server any more.
The outer network node is not provided with a router, has an outer network IP and can also be an inner network node which is successfully punched.
The intranet nodes are network nodes which are not successful in punching and provided with routers, and are usually mounted in an intranet environment of a user, such as a guest playing cloud, a P2P Content Delivery Network (CDN) client, and the like. Due to the limitation of the local area network, the intranet nodes can directly access the extranet nodes, but the extranet nodes cannot directly access the intranet nodes anytime and anywhere.
In the DHT network, an intranet node can establish a TCP long connection and is connected to an extranet node, and after the intranet node is successfully mounted to the extranet node, the extranet node can communicate with the intranet node at any time and any place.
Referring to fig. 2, fig. 2 is a flowchart illustrating a node mounting method according to a preferred embodiment of the present invention. The order of the steps in the flowchart may be changed, and some steps may be omitted.
And S11, when the network node is started, the network node judges whether the network node is an intranet node, if so, the step S12 is executed, and if not, the process is ended.
In the invention, whether the network node is an intranet node can be judged in various ways.
Specifically, the determining whether the network node is an intranet node includes:
acquiring an Internet Protocol (IP) address of the network node;
judging whether the address type of the IP address is the IP address of a local area network or not;
if the address type of the IP address is the IP address of a local area network, determining that the network node is an intranet node; or the like, or, alternatively,
and if the address type of the IP address is the IP address of the public network, determining that the network node is an external network node.
In this embodiment, typically, the network nodes of the IP address of the local network belong to intranet nodes, while the network nodes of the IP address of the public network belong to extranet nodes.
Specifically, the determining whether the network node is an intranet node includes:
sending a second connection request to the server;
if the connection between the network node and the server fails, determining that the network node is an intranet node; or
And if the network node is successfully connected with the server, determining that the network node is an external network node.
In this embodiment, a server (such as a reverse probe server) is deployed on the extranet. When the network node is started, a second connection request can be sent to the server to request for communication with the server, the server tries to establish a new connection with the network node after receiving the second connection request, and if the connection between the network node and the server fails, the network node is determined to be an intranet node; or, if the network node is successfully connected with the server, determining that the network node is an external network node.
After the network node judges the internal and external network attributes of the network node, the network node carries the internal and external network attribute information when communicating with other network nodes subsequently.
In the invention, because the external network node does not need to be mounted, when the network node judges that the network node is the external network node, the external network node can be directly skipped over.
And S12, the network node judges whether the external network node configuration list of the network node has the alternative external network node, if so, the step S13 is executed, and if not, the process is ended.
In the invention, an extranet node configuration list can be created for each intranet node in advance. If a certain intranet node is started for the first time, the configuration list of the extranet nodes of the intranet node is null, that is, there is no any alternative extranet node, and if a certain intranet node is not started for the first time, at least one alternative extranet node is stored in the configuration list of the extranet nodes of the intranet node. Usually, the alternative extranet nodes in the extranet node configuration list are extranet nodes on which the intranet node is successfully mounted in history.
As an optional implementation, the method further comprises:
if the alternative external network nodes do not exist in the external network node configuration list of the network node, detecting the external network nodes in the DHT network;
when a target external network node is detected, establishing short connection with the target external network node;
if the short connection is successfully established, inquiring whether the number of the intranet nodes currently mounted by the target extranet node reaches a second preset number threshold;
and if the number of the currently mounted intranet nodes of the target extranet node does not reach a preset number threshold value, mounting the network nodes on the target extranet node.
In this embodiment, if there is no alternative external network node in the external network node configuration list of the network node, indicating that the network node is first started, it is necessary to detect the external network node in a distributed Hash table (dht) (distributed Hash table) network. When a target extranet node is detected, the network node tries to establish short connection with the target extranet node, if the short connection is established successfully, whether the number of the intranet nodes currently mounted by the target extranet node reaches a second preset number threshold value or not is inquired, and if the number of the intranet nodes currently mounted by the target extranet node does not reach the preset number threshold value, the number of the intranet nodes currently mounted by the target extranet node is not saturated, and the network node can be mounted on the target extranet node.
As an optional implementation, the method further comprises:
and storing the node information of the target external network node into the external network node configuration list.
In this embodiment, since the network node is first started, and there is no candidate extranet node in the extranet node configuration list, the node information of the target extranet node needs to be stored in the extranet node configuration list, so that the node can be subsequently and quickly mounted.
S13, the network node selects a first external network node from the alternative external network nodes in the external network node configuration list.
In the invention, because the alternative external network nodes in the external network node configuration list are external network nodes which are successfully mounted in history, the network node can directly select the first external network node from the alternative external network nodes in the external network node configuration list.
Optionally, the first external network node may be selected according to the priority from the candidate external network nodes in the external network node configuration list according to the priority order of the node update time. Generally, the closer the node update time is to the current time, the higher the priority of the network node, whereas the farther the node update time is from the current time, the lower the priority of the network node.
S14, the network node mounts the network node on the first external network node.
Specifically, a network node may attempt to establish a TCP long connection with the first external network node to mount the network node on the first external network node. Wherein the network node may be successfully mounted or may be unsuccessfully mounted.
As an optional implementation, the method further comprises:
if the network node fails to mount on the first external network node, selecting a second external network node from the external network node configuration list;
mounting the network node on the second external network node;
and deleting the node information of the first external network node from the external network node configuration list.
In this embodiment, a network node may attempt to establish a TCP long connection with the first external network node multiple times (for example, 3 times), each time at an interval of 3N seconds, and if all the multiple attempts fail to mount, it is determined that the network node fails to mount on the first external network node, the first external network node is discarded, and node information of the first external network node may be deleted from the external network node configuration list.
Meanwhile, a second extranet node may be selected from the extranet node configuration list according to priority, and attempt to establish a connection with the second extranet node, and mount the network node on the second extranet node.
As an optional implementation, the method further comprises:
sending a first connection request to each alternative external network node in the external network node configuration list every other preset period;
for each alternative external network node, judging whether the network node and the alternative external network node successfully establish connection;
and if the connection between the network node and the alternative external network node fails, deleting the node information of the alternative external network node in the external network node configuration list.
In this embodiment, due to a change in a network environment or a network node, a situation that some candidate extranet nodes in the extranet node configuration list may be normally connected in a history, but cannot be normally connected currently may be caused, so that validity of the candidate extranet nodes in the extranet node configuration list needs to be detected and updated every preset period (for example, every hour), and once a candidate extranet node that does not satisfy a condition is found, node information of the candidate extranet node needs to be deleted.
Specifically, a first connection request may be sent to each of the candidate extranet nodes in the extranet node configuration list, after each of the candidate extranet nodes receives the first connection request, if the candidate extranet node belongs to a valid node that can be normally connected, the candidate extranet node may attempt to establish a long connection with the network node, and mount the connection, otherwise, if the candidate extranet node belongs to an invalid node that cannot be normally connected, the candidate extranet node may not communicate with the network node, and the network node may not be mounted on the candidate extranet node. Therefore, for each alternative extranet node, it may be determined whether the network node and the alternative extranet node are successfully connected, and if the connection between the network node and the alternative extranet node fails, indicating that the alternative extranet node belongs to an invalid node, the node information of the alternative extranet node may be deleted from the extranet node configuration list, thereby implementing update and maintenance of the extranet node configuration list, and ensuring that the alternative extranet node in the extranet node configuration list is a valid node that can be normally connected.
As an optional implementation, the method further comprises:
if the network node is successfully mounted on the first external network node, judging whether the number of the alternative external network nodes in the current external network node configuration list reaches a first preset number threshold value;
if the number of the alternative external network nodes in the current external network node configuration list does not reach a first preset number threshold value, detecting the external network nodes in the DHT network;
and if the external network nodes meeting the preset requirements are detected, storing the node information of the external network nodes meeting the preset requirements into the external network node configuration list.
In this embodiment, the maximum storage number of the alternative extranet nodes in the extranet node configuration list may be set to a first preset number threshold, such as 20. When the network node is successfully mounted on the first extranet node, the network node may further determine whether the number of the candidate extranet nodes in the current extranet node configuration list reaches a first preset number threshold, if the number of the candidate extranet nodes in the current extranet node configuration list does not reach the first preset number threshold, the network node needs to continue to detect the extranet node in the DHT network, and if an extranet node meeting preset requirements is detected, it indicates that the detected extranet node belongs to an available node, the node information of the extranet node meeting the preset requirements needs to be stored in the extranet node configuration list. On the contrary, if the number of the alternative external network nodes in the external network node configuration list reaches the first preset number threshold, then continuous detection is not needed, and subsequently, the validity of the alternative external network nodes in the external network node configuration list only needs to be detected every preset period so as to update and maintain the external network node configuration list.
Specifically, when a certain outer network node is detected, a short connection can be established with the certain outer network node, if the short connection is successfully established, whether the number of inner network nodes currently mounted by the certain outer network node reaches a second preset number threshold is inquired, and if the number of inner network nodes currently mounted by the certain outer network node does not reach the preset number threshold, it is determined that the certain outer network node meets the preset requirement.
In the method flow described in fig. 2, when any network node in the DHT network is started, if the network node is an intranet node, the network node may directly select any extranet node (i.e., the first extranet node) from an extranet node configuration list in which candidate extranet nodes are stored, and since the candidate extranet nodes in the extranet node configuration list are all the extranet nodes on which the network node has been successfully mounted in the history, the network node can be quickly and efficiently mounted on any candidate extranet node in the extranet node configuration list, so that the mounting efficiency of the network node can be improved.
The above description is only a specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and it will be apparent to those skilled in the art that modifications may be made without departing from the inventive concept of the present invention, and these modifications are within the scope of the present invention.
Referring to fig. 3, fig. 3 is a functional block diagram of a node mounting apparatus according to a preferred embodiment of the present invention.
In some embodiments, the node mounting means operates in a network node. The node mounting means may comprise a plurality of functional modules consisting of program code segments. Program code of various program segments in the node mounting device may be stored in the memory and executed by the at least one processor to perform some or all of the steps of the node mounting method described in fig. 2.

The functional module may include: a first judging module 301, a second judging module 302, a selecting module 303 and a mounting module 304. The module referred to herein is a series of computer program segments capable of being executed by at least one processor and capable of performing a fixed function and is stored in memory. In some embodiments, the functions of the modules will be described in detail in this embodiment.
The first determining module 301 is configured to determine whether a network node is an intranet node when the network node is started.

A second determining module 302, configured to determine whether an alternative extranet node exists in an extranet node configuration list of the network node if the network node is an intranet node.
In the invention, an extranet node configuration list can be created for each intranet node in advance. If a certain intranet node is started for the first time, the configuration list of the extranet nodes of the intranet node is null, that is, there is no any alternative extranet node, and if a certain intranet node is not started for the first time, at least one alternative extranet node is stored in the configuration list of the extranet nodes of the intranet node. Usually, the alternative extranet nodes in the extranet node configuration list are extranet nodes on which the intranet node is successfully mounted in history.
A selecting module 303, configured to select a first extranet node from the candidate extranet nodes in the extranet node configuration list if the candidate extranet nodes exist in the extranet node configuration list of the network node.
In the invention, because the alternative external network nodes in the external network node configuration list are external network nodes which are successfully mounted in history, the network node can directly select the first external network node from the alternative external network nodes in the external network node configuration list.
Optionally, the first external network node may be selected according to the priority from the candidate external network nodes in the external network node configuration list according to the priority order of the node update time. Generally, the closer the node update time is to the current time, the higher the priority of the network node, whereas the farther the node update time is from the current time, the lower the priority of the network node.
A mounting module 304, configured to mount the network node on the first external network node.
Specifically, a network node may attempt to establish a TCP long connection with the first external network node to mount the network node on the first external network node. Wherein the network node may be successfully mounted or may be unsuccessfully mounted.
Optionally, the selecting module 303 is further configured to select a second extranet node from the extranet node configuration list if the network node fails to mount on the first extranet node;
the mounting module 304 is further configured to mount the network node on the second external network node;
the node mounting apparatus further includes:
and the deleting module is used for deleting the node information of the first external network node from the external network node configuration list.
In this embodiment, a network node may attempt to establish a TCP long connection with the first external network node multiple times (for example, 3 times), each time at an interval of 3N seconds, and if all the multiple attempts fail to mount, it is determined that the network node fails to mount on the first external network node, the first external network node is discarded, and node information of the first external network node may be deleted from the external network node configuration list.
Meanwhile, a second extranet node may be selected from the extranet node configuration list according to priority, and attempt to establish a connection with the second extranet node, and mount the network node on the second extranet node.
Optionally, the node mounting apparatus further includes:
a sending module, configured to send a first connection request to each alternative external network node in the external network node configuration list every preset period;
the second determining module 302 is further configured to determine, for each alternative external network node, whether the network node and the alternative external network node successfully establish a connection;
the deleting module is further configured to delete the node information of the alternative external network node from the external network node configuration list if the connection between the network node and the alternative external network node fails.
In this embodiment, due to a change in a network environment or a network node, a situation that some candidate extranet nodes in the extranet node configuration list may be normally connected in a history, but cannot be normally connected currently may be caused, so that validity of the candidate extranet nodes in the extranet node configuration list needs to be detected and updated every preset period (for example, every hour), and once a candidate extranet node that does not satisfy a condition is found, node information of the candidate extranet node needs to be deleted.
Specifically, a first connection request may be sent to each of the candidate extranet nodes in the extranet node configuration list, after each of the candidate extranet nodes receives the first connection request, if the candidate extranet node belongs to a valid node that can be normally connected, the candidate extranet node may attempt to establish a long connection with the network node, and mount the connection, otherwise, if the candidate extranet node belongs to an invalid node that cannot be normally connected, the candidate extranet node may not communicate with the network node, and the network node may not be mounted on the candidate extranet node. Therefore, for each alternative extranet node, it may be determined whether the network node and the alternative extranet node are successfully connected, and if the connection between the network node and the alternative extranet node fails, indicating that the alternative extranet node belongs to an invalid node, the node information of the alternative extranet node may be deleted from the extranet node configuration list, thereby implementing update and maintenance of the extranet node configuration list, and ensuring that the alternative extranet node in the extranet node configuration list is a valid node that can be normally connected.
Optionally, the second determining module 302 is further configured to determine, if the network node is successfully mounted on the first extranet node, whether the number of the candidate extranet nodes in the current extranet node configuration list reaches a first preset number threshold;
the node mounting apparatus further includes:
the detection module is used for detecting the external network nodes in the DHT if the number of the alternative external network nodes in the current external network node configuration list does not reach a first preset number threshold;
and the storage module is used for storing the node information of the external network nodes meeting the preset requirements into the external network node configuration list if the external network nodes meeting the preset requirements are detected.
In this embodiment, the maximum storage number of the alternative extranet nodes in the extranet node configuration list may be set to a first preset number threshold, such as 20. When the network node is successfully mounted on the first extranet node, the network node may further determine whether the number of the candidate extranet nodes in the current extranet node configuration list reaches a first preset number threshold, if the number of the candidate extranet nodes in the current extranet node configuration list does not reach the first preset number threshold, the network node needs to continue to detect the extranet node in a distributed hash table dht (distributed hash table) network, and if an extranet node meeting preset requirements is detected, it is indicated that the detected extranet node belongs to an available node, and the node information of the extranet node meeting the preset requirements needs to be stored in the extranet node configuration list. On the contrary, if the number of the alternative external network nodes in the external network node configuration list reaches the first preset number threshold, then continuous detection is not needed, and subsequently, the validity of the alternative external network nodes in the external network node configuration list only needs to be detected every preset period so as to update and maintain the external network node configuration list.
Specifically, when a certain outer network node is detected, a short connection can be established with the certain outer network node, if the short connection is successfully established, whether the number of inner network nodes currently mounted by the certain outer network node reaches a second preset number threshold is inquired, and if the number of inner network nodes currently mounted by the certain outer network node does not reach the preset number threshold, it is determined that the certain outer network node meets the preset requirement.
Optionally, the detecting module is further configured to detect an external network node in the DHT network if there is no alternative external network node in the external network node configuration list of the network node;
the node mounting apparatus further includes:
the establishing module is used for establishing short connection with the target external network node when the target external network node is detected;
the query module is used for querying whether the number of the intranet nodes currently mounted by the target extranet node reaches a second preset number threshold value or not if the short connection is successfully established;
the mounting module 304 is further configured to mount the network node on the target extranet node if the number of currently mounted intranet nodes of the target extranet node does not reach a preset number threshold.
In this embodiment, if there is no alternative extranet node in the extranet node configuration list of the network node, indicating that the network node is first started, it is necessary to detect the extranet node in the DHT network. When a target extranet node is detected, the network node tries to establish short connection with the target extranet node, if the short connection is established successfully, whether the number of the intranet nodes currently mounted by the target extranet node reaches a second preset number threshold value or not is inquired, and if the number of the intranet nodes currently mounted by the target extranet node does not reach the preset number threshold value, the number of the intranet nodes currently mounted by the target extranet node is not saturated, and the network node can be mounted on the target extranet node.
Optionally, the storage module is further configured to store the node information of the target extranet node into the extranet node configuration list.
In this embodiment, since the network node is first started, and there is no candidate extranet node in the extranet node configuration list, the node information of the target extranet node needs to be stored in the extranet node configuration list, so that the node can be subsequently and quickly mounted.
The first determining module 301 determining whether the network node is an intranet node includes:
acquiring an Internet Protocol (IP) address of the network node; judging whether the address type of the IP address is the IP address of a local area network or not, and if the address type of the IP address is the IP address of the local area network, determining that the network node is an intranet node; or
Sending a second connection request to the server; and if the connection between the network node and the server fails, determining that the network node is an intranet node.
In this embodiment, typically, the network nodes of the IP address of the local network belong to intranet nodes, while the network nodes of the IP address of the public network belong to extranet nodes.
A server (such as a reverse probe server) is deployed on the extranet. When the network node is started, a second connection request can be sent to the server to request for communication with the server, the server tries to establish a new connection with the network node after receiving the second connection request, and if the connection between the network node and the server fails, the network node is determined to be an intranet node; or, if the network node is successfully connected with the server, determining that the network node is an external network node.
After the network node judges the internal and external network attributes of the network node, the network node carries the internal and external network attribute information when communicating with other network nodes subsequently.
In the node mounting apparatus described in fig. 3, when any network node in the DHT network is started, if the network node is an intranet node, the network node may directly select any extranet node (i.e., the first extranet node) from an extranet node configuration list in which candidate extranet nodes are stored, and since the candidate extranet nodes in the extranet node configuration list are all the extranet nodes on which the network node has been successfully mounted in the history, the network node can be quickly and efficiently mounted on any candidate extranet node in the extranet node configuration list, and thus the mounting efficiency of the network node can be improved.
