RAP: a high speed protocol for random access devices

The protocol proposed, the random access protocol (RAP), is designed to offer a high throughput for bulk data transfers between random access devices like disks. The protocol is meant to be used in the data transfer phase of any bulk transfer protocol, and is designed to avoid the drawbacks of the sliding window protocol. The protocol exploits the property of random access to offer a higher throughput than general purpose window protocols, while providing reliable data transfer with error recovery. The author gives a theoretical performance evaluation, comparing RAP to the sliding window protocol, and discusses the prototype implementation and measured throughput
