The well-known Sliding Window protocol caters for the reliable and efficient transmission of data over unreliable channels that can lose, reorder and duplicate messages. Despite the practical importance of the protocol and its high potential for errors, it has never been formally verified for the general setting. We try to fill this gap by giving a fully formal specification and verification of an improved version of the protocol. The protocol is specified by a timed state machine in the language of the verification system PVS. This allows a mechanical check of the proof by the interactive proof checker of PVS. Our modelling is very general and includes such important features of the protocol as sending and receiving windows of arbitrary size, bounded sequence numbers and channels that may lose, reorder and duplicate messages.
