Information center network oriented cache placement decision scoring system based on fluid dynamic theory

Abstract

The invention discloses an information center network oriented cache placement decision scoring system based on a fluid dynamic theory. A service request rate of a node passed by each request is dynamically calculated according to requests sent by a user until a node is hit. Finer-grained evaluation is carried out on the importance of a current node to request contents by employing the service request rates. Moreover, a cache decision process is mapped by employing the fluid dynamic theory. Whether to store cache in a container is decided according to the liquid temperature in the container. The method has the advantages that the hit rate of the information center network oriented cache is effectively improved; the good result also can be obtained when cache resources are limited; the redundancy problem of an information center network can be effectively solved; the backup number of the same contents of the network can be greatly reduced; and the network cache resources can be utilized fully.

Description

technical field [0001] The invention relates to the technical field of network cache, in particular to a cache placement decision scoring method based on fluid dynamics theory in an information center network. Background technique [0002] With the rapid popularization of information technology and Internet applications, the scope and scale of Internet applications have far exceeded the original design intention, gradually replacing some traditional communication media, and becoming an important infrastructure of the current information society. The main body of Internet applications has turned to the acquisition of content such as text information and multimedia audio, and information service content has become the subject of network services. With the rapid development of Internet content and demand, more and more problems are gradually exposed in the current Internet demand. The Internet with the TCP / IP protocol as its core technology is facing increasingly serious techn...
