A GMPLS (Generalized Multi-Protocol Label Switching)-based link restoration scheme with IP-routing stability for data link failure between routers through a PXC (Photonic Cross-Connect) network was proposed and successfully demonstrated in a US nationwide photonic network for the first time.
[Show abstract][Hide abstract] ABSTRACT: The objective of this paper is to survey the Generalized Multi-Protocol Label Switching (GMPLS) based recovery technology for optical transport networks. This paper introduces standardization activities of the GMPLS based recovery technology in the Internet Engineering Task Force (IETF), and recent progress of related experiments. In addition, this paper extracts requirements for the GMPLS based recovery technology through the evaluation of existing network elements, which can be client nodes of the optical transport networks. The results of field evaluations on the GMPLS based recovery technology are also introduced in this paper. Then, this paper addresses the issues for future deployment of the GMPLS based recovery technology for the optical transport networks.
[Show abstract][Hide abstract] ABSTRACT: This paper presents a service and operational based study of a GMPLS-controlled photonic Internet exchange aiming at deployment in the Tokyo metropolitan area. This paper focuses on conceptual studies, namely the service and operation of a photonic Internet exchange, based on a series of experiments conducted over the last few years.
