Problems solved by technology

[0007] However, in this processing method, when the IP address of the client is recognized as an asymmetric routing IP address by the Web Cache system, the Web Cache system will interrupt the current connection of the client, resulting in failure of this access

Embodiment Construction

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly described below in conjunction with the drawings in the embodiments of the present invention.

[0031] First, briefly describe the terms involved in the embodiments of the present invention.

[0032] TCP is a connection-oriented, reliable, IP-based transport layer protocol in the Open System Interconnection (OSI) reference model, which is defined by RFC 793 of the Internet Engineering Task Force (IETF) illustrate. The protocol number of TCP in IP packets is 6.

[0033] HTTP is the most widely used network protocol on the Internet. HTTP provides a way to publish and receive HyperText Markup Language (HTML) pages. RFC2616 describes HTTP 1.1.

[0034] Web Cache is a device deployed between the client and the business server. The business server can also be called a We...

Abstract

The embodiment of the present invention relates to a traffic processing method and a transparent caching system, the method comprising: when the transparent caching system receives from the client a synchronization protocol for establishing the first transmission control protocol TCP connection between the client and the service server When serial numbering a SYN message, the network protocol IP layer forwarding process is performed on the SYN message; if the transparent cache system does not receive the SYN+confirmation ACK response message for the SYN message, then when the transparent cache When the system receives the data message of the TCP stream transmitted through the first TCP connection, it performs IP layer forwarding processing on the data message. It can be seen from the above that in the embodiment of the present invention, the normal access of the client to the Web server during asymmetric routing can be realized.

Description

technical field [0001] The invention relates to the field of computers, in particular to a flow processing method and a transparent cache system. Background technique [0002] With the vigorous development of the Internet, network traffic increases rapidly, which brings great challenges to network operators. The investment in network infrastructure expansion is huge, and it is difficult to match the growth rate of user traffic. About 80% of the current network traffic comes from the Hyper Text Transfer Protocol (HTTP). For example, videos, file downloads, web browsing, etc. all use HTTP. Since HTTP is based on the client / server model, when users access resources It is necessary to obtain the same data from the source site. The more people accessing the unified resource, the greater the duplicate data traffic will be. Providing a cache service through an Internet cache (Web Cache) system is an effective way to solve this problem. [0003] Based on the idea of ​​exchanging ...
