Abstract:
Standard distributed algorithmic solutions to recurring distributed problems are commonly speci ed and described informally. A proper understanding of these distributed algorithms that clari es ambiguities requires formal descriptions. However, formalisation tends to yield complex descriptions. We formally study two broadcast algorithms and present an encoding framework using a process descriptive language and formalise these algorithms and their speci cations using this framework. Following these new formal encodings we discuss correctness proofs for the same algorithms.
