Detailed explanation-1: -Typically, BitTorrent uses TCP as its transport protocol for exchanging pieces, and it uses HTTP for tracker comms. The well known TCP port for BitTorrent traffic is 6881-6889 (and 6969 for the tracker port).
Detailed explanation-2: -The choke algorithm is the peer selection policy used in BitTorrent. The active peer set is determined by this algorithm, which is also denoted as tit-for-tat algorithm.
Detailed explanation-3: -Without an initial seed, or at least leechers which collectively have all pieces, a swarm cannot be successful in that no peer will ever have the full content. In order to get fair reciprocation between participating peers a peer selection algorithm, known as the choking algorithm, is used.
