Protocol Discovery in Multiprotocol Networks

1994 , Ammar, Mostafa H. , Calvert, Kenneth L. , Clark, R. J. (Russell J.)

Multiprotocol systems can be an important tool for achieving interoperability. As the number of protocols available on such systems grows, there is an increasing need for support mechanisms that enable users to effectively access these protocols. Of particular importance is the need to determine which of several protocols to use for a given communication task. In this work, we propose architectures for a protocol discovery system that uses protocol feedback mechanisms to determine which protocols are supported. We describe the issues related to protocol discovery and present feedback mechanisms necessary to support discovery. We present a prototype implementation of a discovery system that supports next generation IP protocols.

On the Use of Directory Services to Support Multi-Protocal Inter-operability

1993 , Calvert, Kenneth L. , Ammar, Mostafa H. , Clark, R. J. (Russell J.)

Multi-protocol systems are a vital tool for achieving inter-operability in today's heterogeneous communication networks. An important aspect of these systems is the need to determine which of the multiple available protocols will be used to carry out a given communication task; an uninformed choice can result in failure to communicate when communication should be possible. In this paper we consider ways to make information about hosts' supported protocol configurations available through directory services. We discuss various representation approaches, and describe a working implementation of a multi-protocol application exemplifying our approach.
