| Abstract: | The BitTorrent peer-to-peer content distribution system adopts the Rate-based Tit-For-Tat(Rate-based TFT) choke algorithm and Optimistic Unchoke(OU) algorithm as a peer selection strategy:Each upload peer employs the Rate-based TFT algorithm to preferentially choose four requesting peers with the highest blocks uploading rates for itself and employs the OU algorithm to randomly choose another requesting peer as its download peers.However,the upload peer which uses the rate-based Tit-For-Tat choke algorithm ... |
| Keywords: | peer-to-peer network choke/unchoke direct contribution indirect contribution global contribution-based peer selection |
