The Local Peer Discovery protocol, specified as BEP-14,
is an extension to the
BitTorrent file-distribution system. It is designed to support the discovery of local
BitTorrent peers, aiming to minimize the traffic through the

bandwidth local area network (LAN).
Local Peer Discovery is implemented with
