Service specification and protocol construction for the transport layer
Sandra Murphy, A. Udaya Shankar · 1988
In a computer network, the transport layer uses the service offered by the network layer and in turn offers its users the transport service of reliable connection management and data transfer. We provide a formal specification of the transport service in terms of an event-driven system and safety and progress properties. We construct three verified transport protocols that offer the transport service. The first transport protocol assumes a perfect network service, the second assumes loss-only network service, and the third assumes loss, reordering and duplication network service.
