Method and device for content distribution

Abstract

The invention discloses a content distribution method and device, which relate to the technical field of communication networks, and can reduce the access delay of users on the premise of ensuring cost. In this embodiment of the present invention, the first content server group periodically counts access delays, and when the access delay is greater than or equal to the congestion threshold, a borrow operation or split operation is performed; when the access delay is greater than the congestion warning threshold and less than the congestion threshold, recycling The borrowed content server may be restored to the state before the merge operation; when the access delay is greater than the idle threshold and less than or equal to the congestion warning threshold, it will be restored to the state before the split operation, return the borrowed content server, and issue a recovery Early warning; when the access delay is less than or equal to the idle threshold, the first content server group is restored to the state before the split operation is performed, the borrowed content server is returned, and the merge operation is performed. The solutions provided by the embodiments of the present invention are suitable for the content distribution process.

Description

technical field [0001] The present invention relates to the technical field of communication networks, in particular to a content distribution method and device. Background technique [0002] The content delivery network is a layer of intelligent virtual network based on the existing Internet, which is composed of content servers. The content server of the traditional content distribution network is located between the core network and the Internet. When receiving a user's access request, it will real-time based on the network traffic, the load status of each content server, the distance from each content server to the user, and the corresponding time. The information assigns the nearest content server to the user, which can reduce the user access delay. [0003] At present, in order to further reduce user access delay, the content distribution network can be lowered to the base station side, and a content server is configured for each base station. When the base station ne...

Problems solved by technology

[0004] However, the number of users carried by a single base station is limited, so the hit rate of data in the content server is low. When the number of users carried by a base station is small, the storage capacity of the content server needs to be extremely large to ensure that enough base stations are configured for each base station through access. The content server can obtain the requested data, but the cost of configuring a large amount of storage for the content server is high, and if the content server is not configured with a large amount of storage, the hit rate of accessing data will be low, resulting in extended user access time, so The existing technology cannot reduce the user's access delay under the premise of guaranteeing the cost
