Abstract
There have been various technical innovations to realize high capacity and reliable communications networks with economical cost. GMPLS (Generalized Multi-Protocol Label Switching) is expected to be one of those technologies and there are various researches, standardization, and inter-operability tests. The Internet Engineering Task Force (IETF) has been developing extension of GMPLS protocols for fault recovery to realize highly reliable networks. Based on the IETF works, Photonic Internet Lab (PIL) has developed a specification enabling implementation and inter-operability for fault recovery of photonic networks, and also studied effective fault recovery mechanism. This paper reports the study, proposes an Extra LSP service utilizing protecting bandwidth of recovery, and proposes how to realize the service.
