Program processing method, system and device

Abstract

The invention provides a program processing method, a program processing system and a program processing device. The method comprises the following steps of: acquiring the theoretical number of copies cached in a distributed Hash table (DHT) network corresponding to the name of a program according to a visitor volume corresponding to the name of the program in a pre-stored program directory at certain time intervals; judging whether the theoretical number of the copies is greater or less than the actual number of the copies, and if the theoretical number of the copies is judged to be greater than the actual number of the copies, performing Hash calculation on the name of the program and numbers of newly added copies according to a Hash algorithm to obtain Hash values corresponding to the numbers of each newly added copy respectively; and carrying the name of the program, the Hash values corresponding to the numbers of each newly added copy corresponding to the name of the program, and an address of a source server in a copy adding message, and transmitting the copy adding message to a cache server corresponding to the Hash values in the DHT network for the cache server to acquire program data corresponding to the name of the program from the source server corresponding to the address of the source server according to the copy adding message and save the program data as the copies.

Description

technical field [0001] The embodiment of the present invention relates to computer network technology, and in particular to a program processing method, system and device. Background technique [0002] At present, the total amount of video programs is relatively large. Although a small number of popular video programs have attracted a considerable number of hits, there are still a large number of visits from a large number of unpopular video programs (the unpopular video programs can be called It is a heavy-end program), although this part of the demand is not large on average for each unpopular video program, but the overall demand formed is still not negligible, so that the distribution of video popularity can meet the heavy-tail characteristics. [0003] For a small number of popular video programs, because there will be a large number of copies of data for each popular video program in the entire network, the optimization method is relatively straightforward. However, fo...

Problems solved by technology

[0003] For a small number of popular video programs, because there will be a large number of copies of data for each popular video program in the entire network, the optimization method is relatively straightforward. However, for a large number of heavy-end programs with less demand, due to the difficulty A large number of copies are formed in the network, and the total amount of data involved is huge. The general optimization method has little effect on it, and even the loss outweighs the gain. heavy end show

[0004] However, in the prior art, since the user directly obtains the required heavy-end programs from the video source server, it increases the huge pressure on the video source server caused by the large amount of traffic brought by the heavy-end program collection as a whole.
