IEEE Std 1394.3™-2003 IEEE Standard for a High Performance
Serial Bus Peer-to-Peer Data Transport Protocol (PPDT) -Description
Abstract: This standard defines a peer-to-peer data transport (PPDT) protocol between Serial Bus devices that implement Serial Bus Protocol 2 (SBP-2). The facilities specified include device and service discovery, self-configurable (plug and play) binding, and connection management.
Keywords: computers, CSR architecture, connect, peer-to-peer, SBP-2, transport protocol
