A request/response protocol for ISO remote operations
Gerald Neufeld, Murray W. Goldberg · 2002
The authors describe the request/response protocol (RRP) which provides protocol support for ISO remote operations. RRP requires no separate protocol data unit (PDU) transfer to establish or release an association. Data transfer is efficient in terms of network utilization, unnecessary retransmissions and acknowledgements. RRP assumes an unsequenced, unreliable, and error prone datagram service. RRP segments and concatenates data too large to be transmitted by the underlying network. It uses selective retransmission to help deal with receiver overrun. RRP optionally monitors client reachability, and monitors server reachability while the client has an outstanding request. RRP is especially efficient for server applications requiring a large number of short-lived connections which transfer small amounts of data.>
