Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. In the description of the present application, the terms "first," "second," and the like are used solely to distinguish one from another and are not intended to indicate or imply relative importance or precedence.
As described above, how to connect different network nodes becomes a key issue to be solved in network connectivity. For example, a client and a server are used as network nodes in a network, and generally need to be connected to each other to implement communication, and how to implement connection between the client and the server is crucial to network connectivity.
Based on this, the embodiments of the present application provide a network node connection method, which can be used for connection between different network nodes. For the convenience of understanding, the inventive concepts of the embodiments of the present application can be briefly described herein.
A Peer-to-Peer network (P2P) is generally an decentralized network, and there is no centralized network device such as a server in the P2P network, but a server, a client, etc. are all used as network nodes in the P2P network, that is, a network node in the P2P network may be a server or a client. In the embodiment of the present application, the P2P network includes a plurality of network nodes, and the network nodes further include a seed node, which is used for publishing configuration information of other network nodes of the P2P network in the P2P network.
Therefore, in the embodiment of the present application, network nodes that need to be connected to each other, for example, a client may be used as a network node (referred to as a client network node) in a P2P network, and a connection server may be used as a network node (referred to as a server network node) in a P2P network, and the client network node and the server network node may be first connected to a P2P network, so as to achieve connection with each other. It should be noted that, here, the client network node and the server network node, which need to be connected, may be the client network node connected to the server network node, or the server network node connected to the client network node, and the following description will take the client network node connected to the server network node as an example.
In the embodiment of the present application, in which the client network node is connected to the server network node, the client network node and the server network node may be connected to the seed node respectively, and the seed node can release the configuration information of other network nodes in the P2P network, so that the client network node can obtain the configuration information of the server network node from the configuration information, and the configuration information of the server network node is used to connect the server network node, thereby implementing connection between the client network node and the server network node. The configuration information of the server network node includes an ip address of the server network node, a network port of the server network node, and a node identifier of the server network node, where the ip address may generally be an ip address of a public network, and the node identifier of the server network node can be used to uniquely identify the server network node, for example, may be a device identifier of a hardware device of the server network node.
Fig. 1 is a schematic specific flowchart of a network node connection method according to an embodiment of the present application, where the method includes the following steps:
step S11: the client network node connects to a seed node in the P2P network.
The specific manner for the client network node to connect the seed node may be that the client network node connects the seed node by using configuration information of the seed node, where the configuration information of the seed node includes an ip address of the seed node, a network port of the seed node, and a node identifier of the seed node. For example, the client network node may first obtain the configuration information of the seed node, and then connect to the seed node by loading the configuration information of the seed node.
Generally, in order to make the P2P network widely used, it is necessary to publish configuration information of the seed node in the P2P network, for example, in a related website. In this way, the client network node can obtain the published configuration information of the seed node, and then connect the seed node by loading the configuration information.
Step S12: the client network node registers with the seed node.
The client network node adds the client network node to the P2P network by registering with the seed node. The specific way for the client network node to register with the seed node may be to send a registration request to the seed node, where the registration request includes configuration information of the client network node, including an ip address of the client network node, a network port of the client network node, and a node identifier of the client network node. In this way, after the seed node receives the registration request sent by the client network node, the client network node may be added to the P2P network, and the configuration information of the client network node is published in the P2P network, so that other network nodes in the P2P network can obtain the configuration information of the client network node.
Step S13: the server network node connects to the seed node in the P2P network.
The server network node may also connect to the seed node using configuration information for the seed node. For example, the server network node may first obtain the configuration information of the seed node, and then connect the seed node by loading the configuration information of the seed node.
Step S14: the server network node registers with the seed node.
The server network node adds the server network node to the P2P network by registering with the seed node. As to the specific manner in which the server network node registers with the seed node, it may also be that a registration request is sent to the seed node, where the registration request includes configuration information of the server network node, including an ip address of the server network node, a network port of the server network node, and a node identifier of the server network node.
In this way, after the seed node receives the registration request sent by the server network node, the server network node may be added to the P2P network, and the configuration information of the server network node may also be published in the P2P network, so that other network nodes in the P2P network can obtain the configuration information of the server network node.
Step S15: the client network node acquires the configuration information of the server network node through the seed node.
Since the seed node publishes the configuration information of the server network node inside the P2P network, the first node can obtain the configuration information of the server network node.
In practical applications, the seed node can distribute the configuration information of the network nodes registered in the seed node in the P2P network by means of distributing the network node list. As shown in table 1, the network node list generally includes a node identifier field, a network port field, and an ip address field, and after the seed node receives a registration request sent by a server network node, the node identifier, the network port, and the ip address of the server network node in the configuration information of the server network node may be respectively added to the node identifier field, the network port field, and the ip address field, and then the network node list is published in the P2P network, so that other network nodes (including client network nodes) in the P2P network can obtain the network node list and extract the configuration information of the server network node from the network node list.
Table 1: network node list
Numbering Node identification Network port ip address
1 ID1 aaa xxx
2 ID2 bbb yyy
n IDn ccc zzz
Of course, after the seed node receives the registration request sent by the client network node, it is obvious that the node identifier, the network port, and the ip address of the client network node in the configuration information of the client network node may also be added to the node identifier field, the network port field, and the ip address field, respectively, and then the network node list is published in the P2P network.
Step S16: the client network node connects to the server network node using the configuration information of the server network node.
After the client network node acquires the configuration information of the server network node, the configuration information of the server network node includes an ip address of the server network node, a network port of the server network node, and a node identifier of the server network node, so that the server network node can be connected by using the configuration information of the server network node.
By adopting the network node connection method provided by the embodiment of the application, in a P2P network, the client network node acquires the configuration information of the server network node through the seed node, and the configuration information of the server network node comprises an ip address of the server network node, a network port of the server network node and a node identifier of the server network node, so that the client network node can be connected with the server network node by using the configuration information of the server network node to realize the connection between the client network node and the server network node.
For example, in practical applications, in order to implement connection between a client and a server, the client and the server may be both used as network nodes in the P2P network, for example, the client is used as the client network node, and the server is used as the server network node, so that the client network node and the server network node are connected to a seed node and are registered separately, so that the seed node publishes configuration information of the client network node and the server network node in the P2P network, and then the client network node can obtain the configuration information of the server network node and connect the server network node by using the configuration information of the server network node. Of course, the server network node can also obtain the configuration information of the client network node, and connect the client network node by using the configuration information of the client network node.
In addition, for the network node connection method shown in fig. 1 in the embodiment of the present application, the order of the steps of the method is not particularly limited, and for example, the method may be executed according to the order of step S11 to step S16; it is also possible to perform step S13 and step S14 first, then perform step S11 and step S12, then perform step S15 and step S16; steps S11 and S12 may be executed in parallel with steps S13 and S14, and then steps S15 and S16 may be executed, or other execution sequences may be possible.
In practical applications, in order to improve the security of the network, a network firewall is usually disposed in a network node, such as the server network node described above. At this time, before the step S16, the method may further include: the random port is generated in a network firewall of a server network node, such as the client network node or the server network node, using a firewall communication protocol, which is used to generate the random port in the network firewall of the server network node. In this case, step S16 may specifically be that the client network node connects with the server network node by using the random port and the configuration information of the server network node, so as to implement the connection between the client network node and the server network node.
It should be further noted that, since the configuration information of other network nodes needs to be published by using the seed node in the P2P network, the single point failure problem is easy to occur. For example, when the seed node fails, it is difficult for the client network node to directly obtain configuration information of the server network node through the seed node, in order to solve the single point failure problem, a standby seed node may be further set in the P2P network, and the seed node may synchronize the network node list to the standby seed node, for example, when the network node list is updated, the network node list includes a network node that is added and a network node that is deleted, and the updated network node list may be synchronized to the standby seed node, and the standby seed node may store the network node list. Thus, in the case of a seed node failure, the list of network nodes can be published using the backup seed node.
For example, after a network node is registered in a seed node, the seed node adds configuration information of the network node to a network node list, so as to update the network node list, and then the seed node may synchronize the updated network node list to a backup seed node, and the backup seed node may store the network node list; thus, in the event of a failure of the seed node, the standby seed node may be used in place of the seed node to publish a list of network nodes on the P2P network.
For example, in the step S15, in the case that the seed node fails, since the backup seed node publishes the network node list in the P2P network instead of the seed node, the client network node may acquire the network node list published by the backup seed node and then extract the configuration information of the server network node from the network node list.
As mentioned above in step S12 and step S14, respectively, the client network node and the server network node send registration requests to the seed node, thereby causing the seed node to add the client network node and the server network node to the P2P network, the registration requests including configuration information of the client network node and configuration information of the server network node, respectively.
For example, the registration request sent by the server network node to the seed node includes configuration information of the server network node, where the configuration information of the server network node includes a node identifier of the server network node, a network port of the server network node, and an ip address of the server network node.
In practical applications, in order to prevent an illegal network node from accessing the P2P network, when a network node registers with a seed node, the seed node usually needs to check the network node. For example, the configuration information included in the registration request sent by the server network node to the seed node may further include a network identifier, so that the seed node can check the network identifier, for example, the network identifier may be compared with the network identifier of the P2P network, if the network identifier is the same as the network identifier of the P2P network, the check is passed, if the network identifier is different from the network identifier of the P2P network, the check is not passed, and only if the check is passed, the seed node adds the server network node to the P2P network. For example, a Universal Unique Identifier (UUID) of the P2P network may be used as the network Identifier of the P2P network.
