In this paper, the authors propose novel wavelength assignment algorithms along with the required extensions to the current GMPLS RSVP-TE Label Set to efficiently encompass the Wavelength Continuity Constraint (WCC) and the Backup Sharing in GMPLS-enabled Wavelength-Routed Networks (WRN) with Shared Path Protection (SPP) recovery schemes. The focus of this paper is to experimentally validate in ADRENALINE testbed the proposed signalling-based solution for WCC in SPP recovery when GMPLS OSPF-TE routing protocol disseminates only aggregated link information at bandwidth level based on two approaches: Unreserved Bandwidth (UBw), as proposed in standard GMPLS, and ShaRable Bandwidth (SRBw) through an extended GMPLS OSPF-TE protocol proposed by the authors.
