Multi-protocol architectures as a paradigm for achieving inter-operability

Abstract: An inclusive approach to achieving heterogeneous system interoperability based on the use of multiprotocol architectures is considered. A detailed description of a framework and model for describing and constructing multiprotocol architectures is given. A case study based on architectures that mix protocols from the OSI and Internet suites is then described. Solutions to the problem of determining which set of protocols to use for a particular communication task are proposed. >

Beyond layering: modularity considerations for protocol architectures

Abstract: This paper considers ways to achieve modularity in protocol architectures without layering. Modularity promotes interoperability by making it easier to port protocol implementations; layering, on the other hand, has been identified as a performance impediment because it enforces sequential processing of messages. Focusing on end-to-end protocols, the authors propose mechanisms (metaheaders and generic interfaces) that support modular parallel or integrated protocol implementations and encourage architecture-independent specifications. An example illustrates interoperability between two systems that support the same protocols, one using traditional layering and the other supporting parallel protocol composition. >
