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.

Abstract

Optical burst switching (OBS) technology is a promising solution for reducing the gap between transmission and switching speeds in future networks. This paper addresses the burst contention resolving mechanism and problem of routing optimization in optical burst switching (OBS) networks. Here, we will discuss the various contentions resolving techniques and focus on one main technique, known as wavelength conversion. For this, theoretical analysis of the performance of switches for wavelength converter in optical burst network is done.

Keywords

Optical Burst Switching, Contention Resolution, Wavelength Conversion.
