High-quality QoS guarantee method for content centric networking

Abstract

The invention relates to the field of a computer network, and particularly relates to a high-quality QoS guarantee method for content centric networking. Content identification tables can be added on routing nodes of the content centric networking to implement content awareness, priority differential transmission of different content feature data packets is implemented by active values, and throughput of the networking is improved, so that high-quality QoS guarantee is provided for contents required by users. The high-quality QoS guarantee method comprises the following contents of: according to content data information of the content centric networking, obtaining traffic classification identification tables in the networking; according to popularity information of content features in the nodes of the content centric networking, obtaining active value categories of different content features; according to active value information of different content features, establishing different priority transmission queues; according to the active value information of different content features and a priority judgment threshold, obtaining probabilities for different content data packets to obtain high priorities; and according to the probabilities for different content data packets to obtain the high priorities, completing the scheduling operation on different priority transmission queues.

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.
