DTP : An E cient Transport Protocol

We recently introduced a new ow control scheme, called send-time control, which is based on a deterministic model of virtual circuits in a computer network. In this scheme, the time at which a packet is sent by a source is computed from estimates of round-trip time, traac in the network and bottleneck service time. In this paper, we describe a new transport protocol, called DTP, which uses send-time control as its ow control scheme. Preliminary measurements of coast-to-coast connections over the Internet show signiicant performance improvement over TCP, which is the most commonly used transport protocol in the Internet today.
