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] Below, the present invention will be further described in conjunction with the accompanying drawings and examples.

[0031] A 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 in , it includes multiple autonomous domains, and each autonomous domain includes multiple access routers, multiple intra-domain mapping servers, and an intra-domain global mapping server;

[0032] The backbone network uses the Chord ring structure to look up global mapping information, and the autonomous domain uses a multi-server backup mechanism to look up intra-domain mapping information. The global mapping server in the domain not only assumes the role of the mapping server in the domain, but also assumes the role of a Chord node. The role of the node is to maintain the Chord ring information for the backbone network, and the role of the intra-domain mapping server is to maintain the intra-domain ...

Abstract

The invention discloses a distributed name-address mapping system and method based on a local cache and a structural P2P, and particularly discloses a distributed name-address mapping implementation method based on the local cache and the structural P2P. The distributed name-address mapping system and method are used for solving the problem of overhead due to a high query time delay and a large-scale query of a GNRS (Global Name Resolution Service) deployment in a traditional name-address mapping service, the consistency of mapping information caching and the stability problem of the system; and the query scale can be effectively reduced, the query path is shortened and the stability of the system is improved.

Description

technical field [0001] The invention relates to a distributed name-address mapping system and method based on local cache and structured P2P, which is applicable to the field of name-address separation mapping systems. Background technique [0002] With the rapid development of the Internet, there are more and more contents on the Internet, and people are gradually not satisfied with point-to-point communication, but are more inclined to obtain content. Therefore, in the design requirements of the future network, it is more necessary to point out the routing of the content rather than the address, and at the same time require better support for mobility. Therefore, separating management of content names and addresses is an important mechanism in the future network, that is, name-address separation mechanism. [0003] The key to realizing the name-address separation mechanism is the name-address mapping service, which is provided by the name-address mapping server GNRS in Mo...
