Recently, the notion of Multicast Service Overlay Network (MSON) has been introduced to address some of the deployment and maintenance problems of IP multicast and application-level multicast. Basically, an MSON is a backbone service overlay provisioned by an MSON provider and designed to “multiplex” several user overlays. The MSON provider designs the backbone overlay for a large user populati...

Topological design of service networks is studied in the paper. A quantitative model and algorithm minimizing cost of processing and delivery are described. An algorithm solving combinatorial problem of optimal design based on binary partitioning, a parametric search and dynamic programming optimization of a binary tree are described and demonstrated in numeric examples.

We propose Architectural Design Rewriting (ADR), an approach to formalise the development and reconfiguration of software architectures based on term-rewriting. An architectural style consists of a set of architectural elements and operations called productions which define the well-formed compositions of architectures. Roughly, a term built out of such ingredients constitutes the proof that a ...
