Association method of BitTorrent and eMule download files

Abstract

The invention provides an association method of BitTorrent and eMule download files. The association method comprises the following steps of: 1) building an eMule information database, wherein the information recorded by the eMule information database comprises collected ED2K link, data size of a resource file corresponding to the ED2K link, and SHA1 value sequences of different sizes of initial file fragments; the sizes of the different sizes of initial file fragments are 2nKB; and the value of n is an integer ranging from 4 to 13; and 2) searching the ED2K link in the eMule network at present according to the file size of the file corresponding to the ED2K link and SHA1 hash values of initial fragments in a BitTorrent information database; and associating a target seed file with current ED2K link. By adopting the association method, repeated downloading of resources files of two P2P spaces of BitTorrent and eMule can be avoided; and the downloading speed can be effectively fastened by utilizing the resources of the P2P spaces of BitTorrent and eMule.

Description

technical field [0001] The invention relates to the technical field of P2P network, in particular, the invention relates to a method for associating files downloaded by BitTorrent and eMule. Background technique [0002] At present, the application of P2P network is developing very rapidly. Because each client can share their own file resources, the cost of publishing files in P2P network is reduced, which greatly facilitates people to share and obtain resources. [0003] BitTorrent (ie BT) and eMule are the two main representatives of the current P2P network, they spread hundreds of millions of resources, many of which are spread in the BT and eMule network at the same time. However, due to the different protocols of the BT and eMule networks, the BT space and the eMule space are independent, and users often can only choose one of the spaces to download when downloading resources. On the other hand, for some unpopular resources, there are relatively few active sharing clie...

AI Technical Summary

Problems solved by technology

However, due to the different protocols of the BT and eMule networks, the BT space and the eMule space are independent, and users often can only choose one of the spaces to download when downloading resources.

On the other hand, for some unpopular resources, there are relatively few active sharing clients in a single P2P space (such as BT space), resulting in extremely slow download speed, and sometimes it will fall into a long-term stagnation state after downloading a part

At this time, even if you find that there are required resources in another P2P space (such as eMule space), you cannot directly use the resources in eMule space to continue downloading, you can only give up the downloaded part in the original P2P space (such as BT space), and re Download in another P2P space (such as eMule space), which leads to a waste of download resources
