DDP: Datagram Delivery Protocol
Datagram Delivery Protocol (DDP), a protocol in the AppleTalk suite, is for socket-to-socket delivery of datagrams over an AppleTalk network. DDP was the lowest-level data-link-independent transport protocol. It provided a datagram service with no guarantees of delivery. All application-level protocols in the AppleTalk suite, including the infrastructure protocols NBP, RTMP and ZIP, were built on top of DDP.
