Embodiment Construction

[0020] Those of ordinary skill in the art will appreciate that the following detailed description of the exemplary embodiments is illustrative only and is not intended to be limiting in any way.

[0021] image 3 It is an application scenario diagram of a distributed system for network byte cache according to an embodiment of the present invention. As shown in the figure, user A can access server A and server B at the same time, and user B can also access server A and server B at the same time. The client cache device C (device C), the server cache device A (device A), and the server cache device B (device B) respectively constitute peer devices. Similarly, the client cache device D (device D), the server cache device A, and the server cache device B also constitute peer devices. A stable information exchange channel is maintained between peer devices.

[0022] The server-side cache device A, server-side cache device B, client-side cache device C, and client-side cache devi...

Abstract

The present invention discloses a network agent cache method and its equipment. The method comprises the following steps: the server cache equipment receives the data block index information from the client cache equipment cache; the server cache equipment receives and saves the data block Index information: the server-side cache device searches the local data block index information according to the generated data block, and if the search is successful, sends the index information corresponding to the data block to the client cache device. The device includes a receiving module, a data generating module, a searching module, a data block recombining module and a sending module. The present invention can reduce the possibility of cache hit failure and error probability, and at the same time optimize the extra pressure on bandwidth resources caused by the index information interaction process.

Description

technical field [0001] The invention relates to network proxy cache technology, in particular to a method for realizing network byte cache and equipment thereof. Background technique [0002] The network byte cache technology is to cache the network resources that the user requests to access locally, and transmit the information to the end user continuously, completely and in real time in the shortest time, thereby reducing the bandwidth load of the network and increasing the data transmission speed. [0003] figure 1 It is the network topology structure of the prior art byte cache (Byte Cache) technology. Such as figure 1 As shown, the network includes a pair of network proxy cache devices, one of which is close to the user who initiates the connection, called the client network proxy cache device, which is used to receive / forward access requests from users and cache corresponding data ; Another network proxy cache device is close to the server, called the server-side ne...
