Mallory Tracy D: Limited automatic repeat request protocol for frame-based communication channels. Broadcom Homenetworking, Mallory Tracy D, PACIULAN Richard J, November 30, 2000: WO/2000/072498

In a frame-switched network, a sender sends frames to a receiver over a possibly unreliable channel. Sent frames include frame identifiers that can be used for a limited automatic repeat request. Upon receipt of a frame, the receiver determines, from the frame identifier, if frames prior to the rece ...
