On Communicating Finite-State Machines
@article{Brand1983OnCF, title={On Communicating Finite-State Machines}, author={Daniel Brand and Pitro Zafiropulo}, journal={J. ACM}, year={1983}, volume={30}, pages={323-342} }
A model of commumcations protocols based on finite-state machines is investigated. The problem addressed is how to ensure certain generally desirable properties, which make protocols "wellformed," that is, specify a response to those and only those events that can actually occur. It is determined to what extent the problem is solvable, and one approach to solving it ts described.

Verifying Programs with Unreliable Channels
- Computer Science, MathematicsInf. Comput.

The verification of a particular class of infinite-state systems, namely, systems consisting of finite-state processes that communicate via unbounded lossy FIFO channels, is considered and it is shown that several interesting verification problems are decidable by giving algorithms for verifying.
Analysis of a class of communicating finite state machines
- Computer ScienceActa Informatica
- 2005
These algorithms have polynomial complexity in terms of size of a global structure of a network, called the shuffle-product, and the relationships between general Petri nets and the class of communicating finite state machines considered here are explored.
A technique for proving liveness of communicating finite state machines with examples

This work discusses a technique to verify that a given node is live in a network of communicating finite state machines, and uses this technique to establish the liveness of three distributed solutions to the mutual exclusion problem.
Decidability of the termination problem for completely specified protocols
- Computer Science, MathematicsDistributed Computing
- 2005
A new class of protocols called completely specified protocols is presented, which are important because they allow for modelling unbounded fifo channels and make it possible to decide the Termination Problem, that is whether the reachability tree is finite or not.
Analysis of Communicating Infinite State Machines using Lattice Automata
- Computer Science
- 2007
This work tackles the problem of the determinization as well as the definition of a widening operator for these automata, and shows that lattice automata are useful for the interprocedural analysis.
A Relational Algebraic Approach to Protocol Verification
- Computer ScienceIEEE Trans. Software Eng.
- 1988
A relational approach is proposed to represent a finite-state machine as a transition table so that logical errors of a protocol such as deadlocks, incomplete specifications and nonexecutable interactions can be formulated in terms of relational algebra.
Probabilistic Lossy Channel Systems
- Computer ScienceTAPSOFT
- 1997
This paper proposes to make the model of finite state machines communicating with each other over unbounded FIFO buffers more realistic by modeling the probability of loss in the buffers and provides algorithms for the probabilistic reachability problem and the Probabilistic model-checking (in linear-time PTL) problem.
Data flow analysis of communicating finite state machines

The central technical contribution of this paper is an algorithm to compute approximations to solutions for the ensuing equations that can be used to check that interactions between the processes are free of nonprogress errors.

- Computer ScienceCSC '89
- 1989
A new correcting method is proposed for a pair of communicating finite state machines and it is ensured that the communication is perfect and progresses indefinitely i.e deadlock-free, liveness, bounded, and without noexecutable transitions, unspecified receptions.
Safety Verification of Communicating One-Counter Machines

A Unified Method for the Specification and Verification of Protocols
