A high-quality qos guarantee method for content-centric networks

Abstract

The present invention relates to the field of computer networks, in particular to a high-quality QoS guarantee method for a content-centric network, which can add a content identification table to a routing node of the content-centric network to realize content awareness, and realize the priority of different content characteristic data packets through active values Differentiate the transmission, improve the throughput of the network, so as to provide high-quality QoS guarantee for the content required by the user, including the following content: according to the content data information of the content-centric network, the traffic classification identification table in the network is obtained; according to the node in the content-centric network According to the popularity information of content characteristics, the activity classification of different content characteristics is obtained; according to the activity information of different content characteristics, different priority transmission queues are established; according to the activity information of different content characteristics and the priority judgment threshold, different content characteristics are obtained The probability that data packets get high priority; according to the probability that different content data packets get high priority, the scheduling operation of different priority transmission queues is completed.

Description

technical field [0001] The invention relates to the field of computer networks, in particular to a high-quality QoS guarantee method for a content-centric network. Background technique [0002] With the continuous development and changes of applications on the Internet, the existing Internet based on TCP / IP has gradually exposed many problems, such as poor security, no mobile support, unreliability, lack of flexibility, limited effectiveness, and rigidity to new applications. In response to these problems, many research institutions at home and abroad are currently conducting research on the design of the future network architecture. [0003] 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...

AI Technical Summary

Problems solved by technology

Although the current content-centric network realizes the transmission and control of content as the core of the network, it lacks the identification of content characteristics and differentiated services for different content characteristics.
