Testbed implementation of control plane extensions for inter-carrier GMPLS LSP provisioning

Abstract

This paper presents a testbed implementation of an inter-carrier GMPLS (Generalized Multi Protocol Label Switching) service architecture recently proposed. This architecture couples the Path Computation Element (PCE)-based control plane with a service plane managing discovery, composition and activation functions of inter-carrier service elements. The testbed implements the required PCE Communication Protocol (PCEP) and Resource Reservation Protocol with Traffic Engineering (RSVP-TE) extensions, together with service request filtering operations performed with a policy based architecture1.
