GMPLS extends MPLS to provide the control for devices in any of following domains: packet, time, wavelength, and fiber. In this way, data from multiple layers are switched over Label Switched Paths (LSPs). The router is equipped with optical-to electrical and electrical-to-optical converters used respectively to terminate and generate optical signals. These interfaces are directly connected to the input and output ports of the optical switch, while the remaining ports accommodate the fibers linking to neighboring nodes. Generalized Multi-Protocol Label Switching (GMPLS) is being developed by the IETF as the industry standard for transport network control planes. In this paper, we tried to analyze the future research in GMPLS networks.

Abstract


GMPLS extends MPLS to provide the control for devices in any of following domains: packet, time, wavelength, and fiber. In this way, data from multiple layers are switched over Label Switched Paths (LSPs). The router is equipped with optical-to electrical and electrical-to-optical converters used respectively to terminate and generate optical signals. These interfaces are directly connected to the input and output ports of the optical switch, while the remaining ports accommodate the fibers linking to neighboring nodes. Generalized Multi-Protocol Label Switching (GMPLS) is being developed by the IETF as the industry standard for transport network control planes. In this paper, we tried to analyze the future research in GMPLS networks.
