Network agent realizing method and device

Abstract

The embodiment of the invention relates to a network agent realizing method and a device, wherein the method comprises the following steps: establishing a first connection used for directly transmitting a data message between a client side and a service side, and detecting whether the received data message needs cache processing or not; if the received data message does not need cache processing,transmitting the data message through the first connection. Due to the fact that the network agent realizing method and the device detect whether the received data message needs cache processing or not, if when the received data message does not need cache processing, the data message is directly transmitted by the first connection, and data messages which do not require cache processing does notneed to be cached and transmitted, the transmitting speed and the processing efficiency of the data message are increased.

Description

technical field [0001] The embodiment of the present invention relates to the field of computer network technology, in particular to a method and device for implementing a network agent. Background technique [0002] With the popularization and application of the network, network security problems such as network attacks, virus file transmission, and spam flooding are becoming more and more serious. Gateway devices such as firewalls, virus gateways, and mail gateways have emerged in response to the urgent needs of operators and enterprise users. In order to restore the application data in the data stream, the gateway device first needs to cache the application data in the data stream. During the process of caching the application data, the gateway device acts as both the client and the server, respectively, and the real service The client communicates with the client, intercepts the application data and caches the application data. During this process, the real client and th...

Problems solved by technology

[0003] In the process of implementing the present invention, the inventor found that the existing technology has at least the following defects: once the proxy connection is established, the gateway device needs to proxy all the connections between the client and the server, and all subsequent data will be forwarded through the gateway device. Because the gateway device first needs to copy the intercepted data in the process of implementing the proxy, then cache the data, and finally forward the data to the destination, which greatly reduces the data forwarding rate and data processing efficiency
