Single-link and time communicating finite state machines

We propose two variants of the classical communicating finite state machines (CFSMs) model, single-link communicating finite state machines (SLCFSMs) and time communicating finite state machines (TCFSMs). For SLCFSMs the notion of well-formedness, which provides a necessary condition for SLCFSMs to be free of some logical errors, is proposed. For TCFSMs, it is argued that they are more suitable for modeling delay-sensitive distributed algorithms/communication protocols. Two practical communication protocols, a token ring and a sliding window protocol, are modeled using TCFSMs.<
