Traffic Grooming of Different Architectures in Optical Networks

Optical networks have increased the transmission capacity of networks tremendously due to different reasons. Wavelength division multiplexing (WDM) is one of the major reasons for the increased capacity. Optical networks are capable of providing a very high speed for huge amount of data transmission. Their transmission capacity is limited due to certain network elements. These elements are electronics in nature and have limited processing capabilities. These electronic devices may be efficiently groomed to enhance the performance of a network. Traffic grooming has become an important issue for research purpose. Due to various advantages offered by traffic grooming, it has gained commercial attention as well. Traffic grooming of a network depends on various parameters. One important parameter is network topology. Ring and mesh network topologies are commonly used in networks as these are suitable for long haul and wide area networks (WAN). So the traffic grooming of ring and mesh network topologies are significant. Various network architectures based traffic grooming is discussed and analyzed in this paper.
