Fair resource distribution strategy based on light-weight content central network framework

Abstract

The invention discloses a fair resource distribution strategy based on a light-weight content central network framework. The strategy comprises the steps of providing a binary tree node distribution model in scenes (such as airports and schoolyards) with relatively simple communication geographical environments; aiming at the binary tree node model, providing a fair resource distribution model fordistributing cache content; in order to solve the resource distribution model, providing a 0-1 integrated planning algorithm with a weight; and providing three indexes such as a hit rate, a network delay and a hit rate variance to assess reasonability and fairness of resource distribution.

Description

technical field [0001] The present invention relates to the technical field of content-centric network, in particular to a fair resource allocation strategy based on a lightweight content-centric network architecture, and an evaluation of the allocation strategy. Background technique [0002] Content Centric Networking (CCN) is one of the important achievements of the current future Internet architecture research. Its core idea is to change the current end-to-end communication mechanism between Internet terminals, separate the content from the terminal location, and publish / subscribe Paradigm (Publish / Subscribe Paradigm) to provide services such as storage and multi-party communication. Specifically, all content transmitted in the network can be regarded as an information object, which can be said to be an information interconnection network rather than a host interconnection. Its core object is information, and each information is identified by the name of the information. ...
