. We consider the problem of establishing consistency of code implementing a network protocol with respect to the documentation as a standard RFC. The problem is formulated as a refinement checking between two models, the implementation extracted from code and the specification extracted from

Today’s software systems communicate over the Internet using standard protocols that have been heavily scrutinized, providing some assurance of resistance to malicious attacks and general robustness. However, the software that implements those protocols may still contain mistakes, and an incorrect

Complex systems have complex errors. Real systems have a variety of mishandled corner cases triggered by intricate sequences of events. In practice, this leaves a residue of errors that cause system crashes but only after days or weeks of continuous execution. When detected, such problems are often very difficult to diagnose because the errors are not reproducible and the sequence of events leading to them cannot be reconstructed. Formal verification methods are a possible way to find and diagnose such deep errors...

approaches dealing with protocol implementation testing which include a binary level verifications and code level analysis of a protocol implementations. In this article we present a formal review on verifications of protocol implementations done through static and dynamic techniques. Recent developments

Abstract—Implementations of network protocols, such as DNS, DHCP and Zeroconf, are prone to flaws, security vulnerabilities and interoperability issues caused by developer mistakes and ambiguous requirements in protocol specifications. Detecting such problems is not easy because (i) many bugs
