Embodiment Construction

[0041] The main purpose of the present invention is to solve the problems of low cache hit rate and large delay, so as to improve the utilization rate of limited cache resources, and then effectively solve the problem of redundant cache in the information center network. At the same time, the flow process of the fluid is calculated in combination with the principles of fluid dynamics, which in turn leads to changes in the volume and temperature of the liquid in the container, and nodes with high temperatures are selected to cache the content, clearly explaining the physical meaning of the cache placement decision process.

[0042] In order to solve the above problems, firstly, the correspondence relation of cache placement decision-making process in fluid dynamics modeling is given. For any network topology G and corresponding node set V, each network node with cache corresponds to a container of the same size, and the volume of the container is large enough. The containers ar...

Abstract

The invention discloses a cache placement decision-making scoring method based on fluid dynamics theory in an information center network. According to a request sent by a user, the service request rate of a node passed by each request is dynamically calculated until the node is hit. Use the request service rate to evaluate the importance of the current node to the request content in a finer-grained manner. At the same time, the fluid dynamics theory is used to map the cache decision-making process, and whether the cache is stored in the container is decided according to the temperature of the liquid in the container. The technical effect of the present invention is that it effectively improves the hit rate of the information center network cache, especially in limited At the same time, it effectively solves the problem of network redundancy in the information center, greatly reduces the number of backups of the same content in the network, and makes full use of network cache resources.

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...
