Detailed Description
For the purposes of making the objects, technical solutions and advantages of the present application more apparent, the technical solutions in the present application will be clearly and completely described below with reference to the drawings in the present application, and it is apparent that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
The relay connection method, apparatus, device and storage medium based on the P2P network of the present application are described below with reference to fig. 1 to 3.
Specifically, the present application provides a relay connection method based on a P2P network, and referring to fig. 1, fig. 1 is a schematic flow chart of the relay connection method based on the P2P network provided in the present application.
The relay connection method based on the P2P network provided by the embodiment of the application comprises the following steps:
step 100, receiving a relay service request sent by a peer, wherein the relay service request carries relay service quality information and identification information of the peer;
it should be noted that, according to the present application, based on the technical idea of SDN (Software-defined network), a controller entity is introduced into the P2P network to manage the real-time state of the relay server, and at the same time, maintain the topological relationship between the relay server and each peer. When a direct link cannot be established between the peers, the peers will request a relay service from the controller, which is responsible for calculating and screening the relay servers and instructing the peers to connect with the optimal relay server designated by the controller.
The present application includes three functional logic entities: a peer, a relay server and a controller, wherein a peer (peer) refers to an entity or individual acting as a node in a P2P network; the relay server is a server which plays a role in forwarding data traffic in network communication; the controller can directly communicate with each peer and the relay server through the P2P network, and is responsible for controlling and managing the relay service and the relay link, and the relay server is responsible for executing communication relay among the peers.
When a P2P initiator peer cannot be connected to a target peer through a direct link, the initiator peer sends a relay service request to a controller, wherein the relay service request carries relay service quality information and identification information of the peer, and the identification information of the peer comprises identification information of the peer of both communication parties; the relay quality of service information may be relay QoS (Quality of Service ) information, including the following information:
bandwidth requirements: indicating the bandwidth requirements of the trunking. For example, the bandwidth requirement may be a fixed value or may be a range or priority level to better match the available relay servers.
Delay requirement: requirements for relay service delay are described. For example, depending on the needs of the application scenario, lower latency is required to implement real-time or interactive applications.
Reliability requirements: indicating the need for reliability of the data transmission. For example, certain applications may have higher requirements for data integrity and reliability, and thus it is desirable to ensure that relay services can provide services with low packet loss rates without losing data.
Other requirements are: other quality of service related requirements such as jitter, throughput, priority, etc. are included.
By providing relay service QoS information, the requesting peer can inform the controller of its desire for relay service, while the controller can select an optimal relay server to meet the demand of the requesting peer according to the QoS information and ensure that an appropriate quality of service is provided.
Step 200, identifying the network location of the peer based on the identification information of the peer;
after the controller obtains the identification information of the peers of both communication parties, the network location of the peer is identified based on the identification information. Specifically, a topology structure of a point-to-point P2P network is obtained; based on the identification information of the peer and the topology, the network location of the peer is identified. For example, the controller may determine that there is a direct connection between the nodes based on the topology, and after it obtains the identification information of the peer, it may identify on which node the peer is located, i.e. the network location of the peer may be obtained.
Or, obtaining a topology table of the peer; based on the identification information of the peer and the topology table, the network location of the peer is identified. For example, the controller may maintain a registry or topology table of peers to record identification information and network location of each peer. When the controller receives the identification information of the peer, the network location of the peer may be queried in a registry or topology table.
Alternatively, if the identification information of the peer is an IP address, the controller may identify the network location of the peer through the IP address based on the fact that the peer typically interacts with the network through the IP address.
Step 300, determining a first target relay server based on the network position and the relay service quality information;
the controller determines a first target relay server based on the network location of the peer and the relay quality of service information. Specifically, determining a distance between the peer and each relay server based on the network location; based on the distance and the relay service quality information, evaluating each relay server to obtain an evaluation result; based on the evaluation result, a first target relay server is determined.
For example, based on the network location of the peer, a correlation index of the distance or network path between the peer and each relay server is calculated, and the relay servers that are closer in distance or reachable through a shorter path may reduce the effects of delay and network congestion, so the scoring of such relay servers is high. Meanwhile, relay service quality information such as bandwidth, throughput, delay, reliability, packet loss rate, resource load, service availability and the like is combined, each relay server is evaluated to determine a comprehensive score of each relay server, and then the relay server with the highest comprehensive score is used as a first target relay server, namely the optimal relay server.
And step 400, sending the connection information of the first target relay server to the peer, wherein the peer establishes a relay link with the first target relay server based on the connection information.
After determining the first target relay server, the controller sends the connection information of the first target relay server to the peer, and then the peer establishes a relay link with the first target relay server based on the connection information. For example, after the controller screens out the optimal relay server, the controller sends connection information such as identification information (e.g. server ID, name, hash value, etc.), address information (e.g. IP address or other network identifier), port information (e.g. communication port monitored by the relay server) and the like of the optimal relay server to the peer of the two communicating parties, so as to instruct the peer of the two communicating parties to establish a relay link with the optimal relay server. After the relay link is established, the communicating peers communicate through the relay server and the relay link.
According to the relay connection method based on the P2P network, a relay service request sent by a peer is received, wherein the relay service request carries relay service quality information and identification information of the peer; identifying a network location of the peer based on the identification information of the peer; determining a first target relay server based on the network location and relay quality of service information; and sending the connection information of the first target relay server to the peer, wherein the peer establishes a relay link with the first target relay server based on the connection information. The method and the device realize control and optimization of relay connection by establishing the controller in the P2P network, thereby improving the resource utilization rate of the relay server, fully utilizing the bandwidth of the physical link, reducing the flow detour and improving the connection performance between peers using the relay link for communication.
Based on the above embodiment, before the receiving the relay service request sent by the peer, the method further includes:
step 110, receiving a registration request sent by a second target relay server;
step 120, based on the registration request, sending a first connection request to a plurality of the peers, wherein the plurality of the peers are connected with the second target relay server based on the first connection request;
step 130, obtaining a first number of the peers successfully connected with the second target relay server;
and 140, if the first number is greater than or equal to a first threshold, adding the second target relay server into a relay server list.
The relay server needs to pass a certain authentication procedure to become an effective node in the network. For example, a relay server may initiate a registration request to a controller, which may communicate the registration request to a plurality of peers to test connectivity of the relay server. The specific flow is as follows:
(1) The second target relay server sends a registration request to the controller, wherein the registration request comprises identity information, basic characteristic parameters and the like of the second target relay server; the second target relay server refers to a relay server that currently needs to be authenticated as a valid node of the network.
(2) After receiving the registration request, the controller communicates the registration request to the plurality of peers, i.e., sends a first connection request to the plurality of peers.
(3) After receiving the first connection request, the peer point tests the second target relay server, namely connects with the second target relay server to judge whether the second target relay server can normally communicate with other peer points.
(4) According to the test result, a first number of peers successfully connected with the second target relay server is obtained, if the first number is larger than or equal to a first threshold value, the second target relay server can be communicated with most of the peers, the stability and the usability of the network can be ensured, and the second target relay server can be added into a relay server list. It will be appreciated that the role of the relay server is to assist in data transfer, to provide connectivity services and to increase the capacity and coverage of the network, if the relay server can be identified as being connectable by a plurality of peers, it is illustrated that it has the basic requirements required by the network nodes, and the task of data transfer between the nodes can be efficiently completed.
(5) If the first number is less than the first threshold, a determination is made that the second target relay server failed registration. That is, if most peers report that the second target relay server is not communicable, it is indicated that the second target relay server may have various problems, such as unstable connection, easy interruption, low data transmission efficiency, etc., which may cause instability and failure of the network, and even affect the normal operation of the entire network, and thus, it is necessary to reject the registration request of the second target relay server.
In the embodiment of the application, the registration mechanism of the relay server can improve the reliability and the security of the distributed network, and ensure that the relay server added into the network can work normally and cannot cause negative influence on the network. Meanwhile, the registration mechanism can also effectively reduce network congestion and improve data transmission efficiency, and provides more stable and efficient network service for users.
Based on the above embodiment, before the receiving the relay service request sent by the peer, the method further includes:
step 150, sending a second connection request to a plurality of the peers, wherein the plurality of the peers are connected with each relay server in the relay server list based on the second connection request;
step 160, obtaining a second number of the peers successfully connected to each relay server;
step 170, sending a first failure notification to the second number of third target relay servers smaller than a second threshold, and removing the third target relay servers from the relay server list.
It should be noted that the dial testing mechanism of the relay server is an important means for ensuring the stability and reliability of the network. The controller periodically instructs a plurality of peers to dial and test the relay server, and through the dial and test feedback result of the relay server, whether the relay server has a fault or is unavailable can be timely found, so that a relay server list can be timely updated, and the normal operation of the network is ensured. The specific flow is as follows:
(1) The controller periodically sends a second connection request to the plurality of peers to dial and test the relay server;
(2) The plurality of peers connect with each relay server in the relay server list based on the second connection request;
(3) The controller obtains the second number of successfully connected peers of each relay server based on the connection condition of each relay server, such as a pulling feedback result;
(4) And sending the first failure notification to a second number of third target relay servers smaller than the second threshold, and removing the third target relay servers from the relay server list. That is, if most peers report that the third target relay server is not communicable, it is indicated that various problems may exist in the third target relay server, and at this time, the third target relay server needs to be removed from the relay server list, and by removing the failed relay server, invalid network resources can be avoided, allocation of the network resources is optimized, and operation efficiency of the network is improved.
According to the embodiment of the application, whether the relay server has a fault or is unavailable can be found in time through the dial testing mechanism and the dial testing feedback result of the peer, and the influence on the network caused by the failure of the relay server is reduced. Meanwhile, by detecting and processing the failure relay server, the connectivity and stability of the network can be ensured, and the reliability and performance of the network can be improved.
Based on the above embodiment, after the sending the connection information of the first target relay server to the peer, the method further includes:
step 310, receiving a second failure notification of the relay link sent by the peer;
step 320, based on the second failure notification, sending the removal information of the relay link to the peer and the first target relay server, and determining a fourth target relay server;
and step 330, transmitting the connection information of the fourth target relay server to the peer, wherein the peer establishes a relay link with the fourth target relay server based on the connection information of the fourth target relay server.
It should be noted that, the failure detection mechanism of the relay server is a mechanism for monitoring the status of the relay link and handling the failure situation in time. When at least one of the two communication peer-to-peer parties detects a relay link failure, a relay server failure notification is sent to the controller to instruct the controller to reselect an appropriate relay server for communication.
Specifically, in the failure detection mechanism, when one of the two communication peer-bodies detects that the relay link fails, a second failure notification of the relay link is immediately sent to the controller, and the notification includes relevant information of the failed link, such as a failed relay server identifier, and the like. After receiving the second failure notification, the controller sends the removal information of the relay link to the peer and the first target relay server, and then reselects the appropriate relay server based on a reselection mechanism of the relay server, so as to ensure the continuity and stability of communication.
The reselection mechanism of the relay server refers to that after the controller receives the relay service failure notification (such as the second failure notification of the relay link), the state information of the peer of the two communication parties and the original relay server is updated, and the appropriate relay server is reselected to establish a new relay connection. The specific process is as follows:
(1) Receiving a relay service failure notification: the controller receives the relay service failure notification sent by the peers of the two communication parties.
(2) Removing the failed relay link state information: according to the failure information in the failure notification, the controller removes the state information of the peer of the two communication parties and the original relay server related to the failure relay link from the record, and ensures that the failure information is not used for subsequent relay service selection any more.
(3) Reselecting the appropriate relay server: the controller reselects the appropriate relay server based on the currently available relay server list and the needs of both the communication, wherein the selection process may be based on various policies such as load balancing, geographic location, etc.
(4) Establishing a new relay connection: after selecting a proper relay server, the controller sends new relay server information to the peers of the two communication parties and assists the two parties to establish new relay connection so that the two communication parties can communicate through the new relay connection.
According to the embodiment of the application, the failure notification is timely sent through the failure detection mechanism of the relay server, so that the relay server can be switched to an available relay server quickly when the relay link fails, and the reliability and the stability of communication are improved. On the other hand, the state information is updated through a reselection mechanism of the relay server, a proper relay server is reselected, a new relay connection is established, and the like, so that communication can be recovered in time after a relay link fails, and the selection of the relay service is optimized according to the current network condition and requirements.
