Cache sharing method, device and system in content distribution network

Abstract

Embodiments of the present invention provide a cache sharing method, device, and system in a content distribution network. The method includes: the first cache server receives a service request, and obtains the first URL of the content requested by the service request; The rule calculates and processes the first URL to obtain a first calculation and processing result; the first cache server determines the cache server identifier corresponding to the first calculation and processing result according to the corresponding rule, and determines whether the cache server identifier is consistent with the first cache server identifier; if , the first cache server determines that the service request is processed by the first cache server; if not, the first cache server determines that the service request is processed by the second cache server identified by the cache server. This embodiment can improve the communication efficiency of the content distribution network.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a cache sharing method, device and system in a content distribution network. Background technique [0002] The content delivery network (Content Delivery Network, referred to as CDN), by adding a new layer of network architecture to the existing Internet Protocol (Internet Protocol, referred to as IP) transmission network, the content of the website is published to the closest to the user terminal The "edge" of the network enables user terminals to obtain the required content nearby, and improves the response speed of user terminals accessing the network. [0003] In the existing CDN server cluster system, multiple cache servers and origin server servers are included. The multiple cache servers implement sharing among the multiple cache servers based on the Internet Cache Protocol (ICP for short). When any cache server receives the service request, if it f...

Problems solved by technology

[0004] However, when the CDN computer room cluster system includes more cache servers, when any cache server misses a service request, the any cache server sends a query message to all other cache servers and waits for the response message from all other cache servers , not only the signaling interaction is complicated, but also leads to access delay and low communication efficiency
