Method, system and device for coverage network interconnection implementation

Abstract

The invention provides a method for realizing interconnection of coverage networks; the method comprises the following steps: a first node in a first coverage network selects a second node which is the only one corresponding to the first node in a second coverage network as the brother node; the first node receives the route request and when the destination network of the route request is confirmed as the second coverage network, the information of the second node is searched according to the route request; and then the route request is sent to the second node according to the information of the second node; when the second node is judged not to be the destination request, the route request is sent to the destination node. The technical proposal of the invention can show that if the request distribution sent by the user terminal is even, every node can receive the route request and the routes for sending the route request to the destination node are different; therefore, the load of every node can be ensured to be balanced and the probability of single-point failure can be reduced and the stability of the coverage network can be improved.

Description

technical field [0001] The invention relates to network communication technology, in particular to a method, system and device for realizing overlay network interconnection. Background technique [0002] Peer-to-peer network (P2P) is a network that has attracted much attention from the IT industry in recent years. Compared with the network of client / server (C / S) and browser / server (B / S) structures, the most significant The characteristic is that there is no central node. [0003] Existing P2P network file sharing systems have uncontrollable shortcomings, that is, it is impossible to predict the resources occupied by the file sharing system, the time required for searching in the file system, and the bandwidth required by the file system cannot be predicted. . In order to solve the uncontrollable shortcomings of the file sharing system, the industry proposes a scalable overlay network, which is mainly configured based on a distributed hash table (DHT). Later, evolutionary ...

AI Technical Summary

Problems solved by technology

[0007] First, in terms of interconnected organization, P4 proposes to broadcast in a tree structure, and transfer information through the DHT proxy server, but this structure will increase the burden on the DHT proxy server

There will be a problem that the DHT proxy server in the DHT network is overloaded, while other servers are lightly burdened, and the load balance of the nodes in the network cannot be guaranteed, so there will be downtime due to the heavy burden of the DHT proxy server, resulting in Instability of DHT network

[0008] Second, each DSP must set up one or more DHT proxy servers, and use domain name server (DNS) to redirect the routing request of the user terminal to the server set up, so it is necessary to modify the information of the user terminal, which will cause system costs improvement

[0009] Third, when a new DHT network joins the Internet, it is necessary to update all DHT proxy servers and add new member information, so the workload required for maintaining the system is relatively large

For example, establish the corresponding relationship between the DHT proxy server and the user terminal, and the user terminal communicates with the user terminal or server in other DHT networks through the DHT proxy server serving it. These operations will undoubtedly increase the complexity of the system

[0011] It can be seen that in the prior art, the technical solution for realizing DHT network interconnection cannot guarantee the load balancing of nodes in the network
