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.
