A Novel Framework For Model Checking Udp Network Interactions, Billy Rathje Jan 2013

A Novel Framework For Model Checking Udp Network Interactions, Billy Rathje

Summer Research

This poster presents the first Java Pathfinder extension to model realistic User Datagram Protocol (UDP) networking communications, which is used to verify a UDP network software simulator, RF. Java Pathfinder is a model checking software system developed by NASA and used frequently for verifying that concurrent software systems avoid deadlock states and other errors. It does not natively support network modeling. NetIOCache is a Java Pathfinder extension for verifying TCP/IP networks, but no similar UDP extensions currently exist. NetStub, a Java Pathfinder extension, can simulate UDP behavior as a collection of threads, but it does not simulate important and common …
