Route forwarding method for content internet

Abstract

The invention provides a route forwarding method for the content internet. Before the method is implemented, a content routing table recording a content name prefix and a next-hop router is constructed and stored in advance according to the content name prefix of data stored in other routers in the current network. The method comprises the following steps of when any router receives a content request, inquiring whether data matched with a content name prefix requested by the current content request exists in a local cache or not; if so, enabling the router to send the data matched with the content name prefix requested by the current content request in the local cache to a requesting party of the current content request along the original route; otherwise, looking up a record matched with the content name prefix requested by the current content request in the content routing table locally stored in advance; and forwarding the current content request to the next-hop router recorded in the record matched with the content name prefix requested by the current content request. After the method is applied, the hit rate and the network forwarding efficiency of the data can be improved.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a routing and forwarding method of the content Internet, which is used to realize the interconnection of content information. Background technique [0002] Now the main usage requirement of the Internet is the acquisition and distribution of content. Although the application has undergone such great changes, the architecture of the Internet is still the Host-to-Host (host-to-host) communication mode, which mainly publishes and obtains information. The current Internet, the Host-to-Host communication mode has obvious deficiencies, and cannot meet the network service needs of existing users. According to the needs of existing users, the Internet will shift from connection-oriented to content-oriented, and realize the interconnection of content. [0003] The content-centric network replaces the traditional IP with the content name, changing the Host-to-Host communication mode. ...

Problems solved by technology

[0010] In order to solve the problems that the existing content Internet lacks the accuracy of the search target content, the network overhead is large, and the redundancy between the networks is too large, the present invention provides a routing and forwarding method for the content Internet. This method ensures that the network is content-centric Under the circumstances, it can make up for the current deficiencies in content Internet forwarding, improve content hit rate, improve network user experience, reduce inter-network redundancy overhead, and reduce data return delay
