Network Control Plane and the MUPPET project Mauro Campanella INFN-GARR [email protected] Network Control plane Lots of interest because: • request for dynamic network topologies (Bandwidth on Demand, Grids, virtual communities) • e2e performance guarantees • fiber abundance and DWDM • mixed packet and circuit switched network • specific application (HEP, RadioTelescopes, HDTV,…) Which protocols and architectures are around ?

The test bed will represent a multi-layer network based on IP/MPLS and ASON/GMPLS technologies, equipped with a unified control plane and designed to support the highly demanding applications of the European research community M.
