example application. Finally, section 6 provides conclusions Future network environments are likely to be used and future work. by cooperative applications. Indeed, the recent advent of peer- to-peer systems where participants collaborate together in an ordered fashion motivates this assumption. In this paper, we present a method that relies on graphs as well as graph gram- mar productions in order to automatically refine a high level Service interactions representation of a given activity into a de- ployment topology at the Middleware and the Transport level. At the middleware level, a formal algorithm is presented in or- der to further optimize the solution. Similarly, at the Transport level, an analytical model to optimize the provisioning in the context of a modular transport protocol implementing collab- orative congestion control is presented. The different models and algorithms are implemented in a case study of CMS-like operations for crisis management.
