Method for saving export bandwidth of backbone network by cache acceleration system

Abstract

The invention discloses a method for saving the export bandwidth of a backbone network by a cache acceleration system, which comprises the following steps of: accelerating a hyper text transport protocol (http) request of a user by using the cache acceleration system, dynamically allocating the http request of the user according to the load condition of the cache acceleration system, realizing the process of making user Internet protocol (IP) addresses corresponding to public network export IP addresses one to one by using real-time authentication data and firewall network address translation (NAT), performing storage and reutilization on duplicate resources according to a target http request format, providing a user authentication management system of Web by using the cache acceleration system, and performing authentication according to the user request by using a proxy server. By the method, the massive needs of providers and enterprise users in the bandwidth are satisfied, monitoring management requirements, which cannot be met by the industry, corresponding to private network and public network IP addresses of a metropolitan area network are preferably met, public network export bandwidth resources can be saved by about 28 percent, and resources and public network export investment are reduced.

Description

technical field [0001] The invention relates to resource allocation technology, in particular to a method for saving backbone network egress bandwidth through a cache acceleration system. Background technique [0002] The slow speed of obtaining information online has become an important factor restricting the development of the Internet. How to increase the speed for users to obtain information under the existing network resources has become a major problem that plagues many enterprises and service providers. [0003] Web caching devices can be installed in different locations on the network, and the ways to implement web caching include proxy caching, transparent caching, and reverse caching. [0004] Transparent access is a capability of Web cache, that is, the ability to accept and respond to user access to any Web server on the Internet. It responds to the user's visit with the IP address of the source server, and the user does not feel that they are accessing the loc...

AI Technical Summary

Problems solved by technology

[0007] 1. The processing capacity of a single device is limited, and there is no ready-made device that can directly meet business needs. The host will become the bottleneck of business development, and expansion

[0008] 2. Traditional Cache devices are generally not dedicated traffic processing devices, and a lot of capacity will be consumed in data analysis and forwarding. The most important purpose of Cache cannot be used, which is to accelerate local access to static resources through Cache.

[0009] 3. In terms of Cache device deployment, whether it is a policy path or a bypass, a large amount of traffic will lead to insufficient processing capabilities of the device. It is necessary to provide cooperation with the stability of the collaborative device so that the failure of the Cache system does not affect the use of users. Insufficient scalability for different businesses

[0010] While the traditional Cache device accelerates, it cannot be exported by the policy route or the source of the request in the metropolitan area network. It cannot be supervised, and there is a legal risk
