Abstract

This paper presents our service specification for the Internet Open Trading Protocol (IOTP) developed using Coloured Petri Nets. To handle IOTP's complexity, we apply a protocol engineering methodology based on Open Systems Interconnection (OSI) principles consisting of five iterative steps: the definition of service primitives and parameters; the creation of an automaton specifying the local service language for each of the four trading roles of IOTP; the development of a CPN model synthesizing the local automata into a specification of the global service capturing the correlations between the service primitives at the distributed trading roles; the generation of the occurrence graph representing the global service language; and lastly a new step, language comparison to ensure the consistency between the specifications of the local service language and the global service language. The outcome is a proposed formal service specification for IOTP.
