A framework for model checking UDP network programs with Java pathfinder

Abstract

Complex asynchronous, distributed systems could benefit significantly from model checking, but model checking programs do not natively support verification of distributed software. Several frameworks have been developed recently that apply model checking to networked software, but none of these frameworks support complete modeling of programs that use the User Datagram Protocol (UDP). This paper presents the first framework to model realistic rather than ideal UDP network operations using Java Pathfinder, and describes its use in verifying a distributed UDP-based application.
