Client networking access method and device in P2P system

Abstract

The invention discloses a client networking access method and device in a P2P system, relates to the technical field of Internet, and can meet the service performance requirements of high availability, high performance and low delay of the P2P system. The method comprises the following steps that a message queue service and a discovery service are deployed in each node in a P2P system, and each client completes registration in a message queue server and a discovery server of a nearby node; a subscription theme of each client is received through the message queue server of the nearby node, the subscription theme is reported to the discovery service through the discovery server, and the subscription theme comprises information of a message queue node to which each client belongs and identity information of the client; an opposite-end client obtains the subscription theme through the discovery service, and sends the subscription theme of the opposite-end client to the client through a corresponding message queue; and the client and the opposite-end client respectively establish a networking channel based on the subscription theme of the opposite side. The method provided by the scheme is applied to the device.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method and device for network access of a client in a P2P system. Background technique [0002] On the Internet, most of the clients of the P2P system are located behind NAT devices, and the mutual communication between clients needs to perform NAT traversal first. Before NAT traversal, the clients need to exchange information, because the exchange information is dynamic Therefore, it has high requirements for timeliness, which requires a third-party service deployed on the public network to support the business, and the message queue can better realize this business model. [0003] In the P2P system, since a large number of clients need to try to connect with each other, initiate message interaction, and subscribe topics and subscribers (clients) frequently change, there are high requirements for the number of channels for subscribing topics in the message queue. There a...

Problems solved by technology

[0004] Among them, the defect of method 1 is obvious. The amount of message forwarding between nodes is large. Due to the repeated sending of messages, the efficiency is low. The more nodes in the cluster, the greater the overhead, wasting resources, especially bandwidth resources, which is not conducive to the horizontal expansion of services; method Second, the information of subscribers needs to be synchronized between nodes. The synchronization time interval will affect the forwarding efficiency. Data synchronization also increases the process complexity of coupling between nodes and message queues. In a P2P system, due to the large number of subscription topics, subscribers change quickly , frequent synchronization will lead to high synchronization overhead in cross-regional computer rooms, and if the synchronization gap is large, it will cause the clients to fail to communicate with each other in time, increase the access delay of the P2P system and reduce the connectivity rate of the P2P system, thereby reducing the P2P System Savings Ratio

It can be seen that the message queues currently on the market are difficult to meet the high-availability, high-performance, and low-latency requirements of P2P system business requirements.

At present, all kinds of message queue software have the above two problems, and the construction scale is large and the complexity is high.
