Multi-region networks (MRN) is the generalized multi-protocol label switching (GMPLS)-based solution for vertical integration. Considering limitations of current interworking models and requirements for integration, MRN gives the possibility to operate domains hosting several technologies as a single network. While using a single instance of the control plane, multi-layer operations are profiled and optimized thanks to a limited number of protocol extensions. Routing and signaling are extended in order to support internal node adaptation capability and deterministic switching capability indication along the explicit route, respectively.
