A cache acceleration method in LAN environment

Abstract

The invention discloses a cache acceleration method under local area network environment, comprising the following steps: carrying out format matching judgment on paths by obtaining the resource paths of all links in the page; for matched paths, sending the paths to a server through http proxy protocol by a client computer, and judging whether files corresponding to the paths are stored locally by the server, if so, extracting the files and transmitting to the client computer from the local, if not, synchronously transmitting to the client computer by connecting the files corresponding to the download of the paths. Some network large-capacity files are cached to the service locally, much bandwidth can be saved for the local area network, and the requirement of the local area network to the bandwidth is reduced, so that the fund is saved; and simultaneously the user experience of net citizen in the local area network can be promoted, and the service quality of some network application programs with relatively high real-time requirement is ensured, so that the local area network is simple to maintain and the complexity of flow control software is decreased.

Description

technical field [0001] The invention belongs to the technical field of network communication, and in particular relates to a cache acceleration method in a local area network environment. Background technique [0002] The rapid development of the Internet has brought great convenience to people's work and life, and the requirements for Internet service quality and access speed are getting higher and higher. Although the bandwidth continues to increase, the number of users and the corresponding bandwidth requirements are also increasing , affected by factors such as bandwidth and transmission distance, the problem of slow response is often complained and troubled. [0003] The method for improving the quality of service of the local area network in the prior art mainly proceeds through the following three aspects: [0004] (1) Increase the bandwidth; generally, you only need to pay money to increase the bandwidth. But no matter how much bandwidth is added, some customer nee...

Problems solved by technology

But no matter how much bandwidth is added, some customer needs can be easily occupied. For example, a high-definition movie may occupy dozens of GB, no matter how much bandwidth is occupied, it will be full.

[0005] (2) Limit user bandwidth; it is necessary for the network administrator to have some understanding of the router before it can be configured, and the upper and lower limit bandwidth that the client can occupy is set on the router

In short, the delay is very unpredictable

[0011] The order of transmission is wrong; when a group of related data packets are routed through the Internet, different data packets may choose different routers, which will cause each data packet to have a different delay time; the order in which the final data packets arrive at the destination will be different from the data The order of packets sent from the sender is inconsistent. This problem requires a special additional protocol to reorganize out-of-order packets.
