A cache acceleration method and system for network data transmission

Abstract

The invention discloses a caching acceleration method and a caching acceleration system for network data transmission. The method comprises steps that an access request sent by user side equipment CPE is received by a virtual access gateway VAR; that the network resource data corresponding to the access request is stored in a content cashing area of the network side is determined by the VAR, a control command is sent to the CPE; the network resource data is extracted by the CPE from a transmission caching area of a user side according to the control command, and the network resource data is further sent to a client. Through the method and the system, two-stage cooperation caches are employed, data packet identification and processing are not required by the CPE, only replacing and storing data blocks according to the control command is needed, so the network acceleration function after network edge virtualization is realized, a caching control command is transmitted between two-level caches by utilizing front 16 bytes of a data packet of an Ethernet frame, and cooperation can be carried out through any two-level network, and changing the transmission equipment of the access network is not required.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a cache acceleration method and system for network data transmission. Background technique [0002] Cache acceleration is to store the accessed data in the cache, and extract this data from the cache when it is accessed again. By reducing repeated visits and low-value traffic, it can achieve the dual value of reducing Internet traffic and improving users' online experience, and can realize Internet Convergence and accumulation of content, in-depth mining of user needs, and provide a foundation for future value-added operations. With the further development of virtualization technology and the requirement of simplifying the configuration and use of user equipment and reducing costs, network edge virtualization technology, that is, virtual access gateway VAR, appears, moving the functions of layer 3 and above to the network side for implementation, and the user side equip...

AI Technical Summary

Problems solved by technology

In the network edge virtualization environment, since the new CPE device only has simple layer 3 functions or even only layer 2 functions, the cache acceleration function based on data above layer 3 such as remote access paths cannot be realized on the new CPE device. And if the cache is also moved up to the network side, the reading of the local cache becomes real-time reading from the network side, and the acceleration effect is almost ineffective.
