LOAD BALANCING METHOD AND APPARATUS, PROXY DEVICE, CACHE DEVICE AND SERVING NODE

摘要

The present disclosure relates to a load balancing method and apparatus, a proxy device, a cache device and a serving node. The method comprises: storing a file in blocks, and specifically scattering the file content to different cache parties relatively evenly in a block form; and when a request party requests the file, mapping a content request of the file into at least one block request; and obtaining, on the basis of the at least one block request, from at least one cache party, at least one block content available for constituting a complete target file, so as to realize a response to the request party. As the size of the block content corresponding to each block request is relatively uniform, and accordingly, the traffic of the requested file is evenly distributed to different cache parties, the internal network traffic of different cache parties is relatively balanced, which causes no bottleneck to the use of the bandwidth of an external network, improving the external network service capability of a network such as a CDN.
