Abstract: This paper reports a practical experience of implementing a group communication service using a protocol composition framework. Specifically, the paper describes the implementation of a Light-Weight Groups (LWG) service on the Ensemble system. This is an interesting case-study because the LWG service is very demanding in terms of protocol composition since its implementation requires the use of forked shaped protocol stacks that are reconfigured at run-time. The insights that we have gained with the exercise are being used in the development of a new composition framework called Appia.
