Abstract

The invention discloses a data piece equipartition selecting system and method based on the number of client-sides and belongs to the information technology processing field. The system comprises a server-side, a Tracker server and the client-sides. The method comprises the following steps: the server-side encoding data to form a seed document, and analyzing the seed document to be connected to the Tracker server; the server-side sending parameters of selection orders of the seed document and data pieces to the client-sides; after receiving the parameters of the selection orders of the seed document and the data pieces, the client-ends analyzing the seed document and conducting data pieces selection and data loading according to the number of the data pieces of the seed document and the parameters of the selection orders of the data pieces. The data piece equipartition selecting system and method solves the problem that in a data piece random selection strategy, data pieces in a BitTorrrent system is not evenly distributed.

Description

[0001] technical field [0002] The invention relates to a data slice selection system and method based on the number of clients, and belongs to the field of information technology processing. Background technique [0003] In the BitTorrent (BT) system, one of the most important features of the BitTorrent protocol is to divide files into data fragments with smaller granularity. This mode releases the service capabilities of a large number of nodes in the download process. The fragment selection algorithm designed for data fragmentation It is the key to the success of the BitTorrent protocol. The segment selection algorithm is a scheduling strategy implemented locally by each node. Each node in the BitTorrent system saves the distribution of shared resource segments of their neighbor nodes through bitfield messages and have messages. Nodes use this information and the segment selection algorithm to decide which segment to download, trying to keep the system as stable as poss...
