Embodiment Construction

[0032] The present invention will be further described now in conjunction with accompanying drawing.

[0033] Before describing the method of the present invention in detail, the concepts involved in the present invention will be briefly described first.

[0034] System: The system involved in the present invention refers to a system composed of intelligent routers.

[0035] Coverage refers to the ratio of the number of neighbors (including yourself) that store the required data in the neighbors to the total number of neighbors, and it is recorded as CR, 0≤CR≤1.

[0036]The service hit rate refers to the probability that the service requested by the user is finally provided by the system, denoted as N ser / N req . Among them, N ser Indicates the number of times the system successfully provides services in the user's request; N req Indicates the number of service requests for all users.

[0037] The content hit rate refers to the probability that the system will successfu...

Abstract

The invention relates to a pre-disposition method for router expansion content distributing network with storage. The pre-disposition method includes the steps of obtaining the parameters of a smart router, acquiring files, of which the content access amount ranking top N, to obtain a set {Ti}, acquiring access amount, normalizing the access amount into hot degree, obtaining a plurality of data sets about hot degrees, determining the optimal parameters of time sequence models by using obtained time sequence models for hot degree data set training, predicting the hot degree of each Ti at the next moment to obtain a hot degree distribution curve, using a step function to simulate the coverage rate distribution of {Ti}, determining the segment number and segment position of the step function, fitting the coverage rate and hot degree curve of each segment, calculating the value of the coverage rate of the {Ti} under the prerequisite of satisfying the storage capacity restriction, and calculating the hit rate of a system formed by the smart router. When the storage capacity is limited, the coverage rate is adjusted to optimize the hit rate, and the content pre-disposition is carried out according to the coverage rate.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a pre-deployment method for extending a content distribution network by a router with storage. Background technique [0002] With the continuous development of network technology and communication technology, the scale of various business servers and intelligent routers is increasing, and the types of services that can be provided to users are also continuously enriched. come higher. In order to reduce the consumption of network resources and reduce the burden on users to find information, the content distribution network (CDN) can pre-distribute various content in the form of files to the content server as a distributed cache. The edge of the user's network, so that users can get the content they need close to them. Specifically, by applying technologies such as distributed caching, load balancing, and traffic engineering, it provides various content distribution and servi...
