Experimental Link Resource Manager Implementation for the ASON/GMPLS CARISMA Network

The control plane has emerged as the key entity of the International Telecommunications Union (ITU-T) Automatic Switched Optical Network (ASON) architecture, enabling both soft-permanent and switched connection establishment. The fundamental control plane functional module is the Optical Connection Controller (OCC) which in turn, is divided in four sub-modules. The Link Resource Manager (LRM) is the sub-module responsible for maintaining both control and transport plane resources. This paper presents the one implemented in the ASON/GMPLS CARISMA network. The included experimental results reflect its applicability in metropolitan environments.
