Caching information pushing device, member, method and system and local area network

Abstract

The invention relates to caching information pushing device, member, method and system and a local area network. The device is arranged in a local area network with a wide-area-network caching acceleration device; and according to data caching information stored in the wide-area-network caching acceleration device, network information of all the local area networks, which is provided with the certain data caching information, is acquired, so that network information of other local area networks is pushed to all the local area networks, and for the certain data caching information, caching acceleration of data stream is performed between any two local area networks in all the local area networks through the wide-area-network caching acceleration devices of the two local area networks. Therefore, the local area network of each client side can know the network information of the local area networks of other client sides with the same caching data, the learning mechanisms of the local area networks of the client sides are enhanced, the trouble that the caching acceleration effect can only be taken when the same data is re-transmitted between two wide-area-network caching acceleration devices through which the data stream pass is avoided.

Description

technical field [0001] The present invention relates to an information push device and method, more specifically, to a buffered information push device, component, method, system and local area network. Background technique [0002] For applications based on web services, the performance will be reduced due to the limitation of bandwidth in the wide area network. Aiming at the shortage of bandwidth, the WAN acceleration cache device generally uses compression and cache technology to ensure full utilization of bandwidth. In specific work, when the client LAN and the server LAN transmit new data for the first time, the respective WAN acceleration cache devices in the client LAN and the server LAN will cache the new data, and the transmission between the client LAN and the server LAN will be the same For the data, it can be encoded in the WAN acceleration cache device of the sender, only the index value is transmitted on the WAN, and then the index value is decoded in the WAN ...

AI Technical Summary

Problems solved by technology

At present, the server-side LAN is transmitting a certain data with a client-side LAN, and at the same time, the server-side LAN is transmitting the data with another client-side LAN. However, there is no caching effect when the data is transmitted between the two for the first time, because the two client LANs do not know that the other party has cached data
