Problems solved by technology

However, the traditional global mapping server GNRS deployment scheme has problems such as extended query time, heavy network load, and high overhead of the mapping server.
At the same time, the actual network is divided into multiple autonomous domains (AS), and each domain may generate a large number of mapping information search requests, and the deployment of the global mapping server does not conform to the actual situation.

Embodiment Construction

[0030] Hereinafter, the present invention will be further described with reference to the drawings and examples.

[0031] The distributed name address mapping system based on local cache and structured P2P of the present invention has a structure such as figure 1 As shown, multiple autonomous domains are included, and each autonomous domain includes multiple access routers, multiple intra-domain mapping servers, and one intra-domain global mapping server;

[0032] The backbone network adopts the Chord ring structure to be responsible for the global mapping information search, and the autonomous domain adopts the multi-server backup mechanism to be responsible for the intra-domain mapping information search. The intra-domain global mapping server not only assumes the role of the intra-domain mapping server, but also assumes the role of the Chord node, among which is Chord The role of the node is to maintain the Chord ring information for the backbone network, and the role of the intr...

Abstract

The present invention proposes a distributed name-address mapping system and method based on local cache and structured P2P, specifically a distributed name-address mapping implementation method based on local cache and structured P2P. The present invention is used to solve the problems of high query delay and overhead caused by large-scale query in the deployment of the global mapping server GNRS (Global Name Resolution Service) in the traditional name address mapping service, the consistency of the mapping information cache and the stability of the system, It can effectively reduce the query scale, shorten the query path and improve the stability of the system.

Description

Technical field [0001] The invention relates to a distributed name and address mapping system and method based on local cache and structured P2P, and is suitable for the field of name and address separation mapping systems. Background technique [0002] With the rapid development of the Internet, there is more and more content on the Internet, and people are gradually not satisfied with peer-to-peer communication, but are more inclined to obtain content. Therefore, in the design requirements of future networks, what is needed more is to point out the routing of content rather than addresses, and at the same time require better support for mobility. Therefore, separating the management of content name and address is an important mechanism in the future network, namely the name and address separation mechanism. [0003] The key to the realization of the name-address separation mechanism is the name-address mapping service. In MobilityFirst, this service is provided by the name-addre...
