Survivable Traffic Grooming in WDM Optical Networks
Traffic grooming, in which low-rate circuits are multiplexed onto wavelengths, with the goal of minimizing the number of add-drop multiplexers (ADMs) and wavelengths has received much research attention from the optical networking community in recent years. While previous work has considered various traffic models and network architectures, protection requirements of the circuits have not been ...
متن کاملTraffic Grooming and Blocking Optimization in all-optical Networks
The paper proposed an efficient traffic grooming model for all optical networks. The model has low complexity and it can be easily implemented for traffic grooming problems. It is used to calculate the blocking probability of computer networks and then grooming problems are addressed based on the calculated blocking probability. Blocking probability is considered to be a major parameter during ...
متن کاملMetaheuristic Approaches to Traffic Grooming in Wdm Optical Networks
The widespread deployment of WDM optical networks posts lots of new challenges for network designers. Traffic grooming is one of the most common problems. Efficient grooming of traffic can effectively reduce the overall cost of the network. But unfortunately, traffic grooming problems have been shown to be NP-hard. Therefore, new heuristics must be devised to tackle them. Among these approaches...
متن کاملResearch Problems in Dynamic Traffic Grooming in Optical Networks
Traffic grooming has recently emerged as an important area in wide area wavelength-routed optical networks research. This research area addresses the problem of multiplexing lower rate traffic demands into wavelength channels of high bandwidth, so as to reduce network equipment cost by maximizing the optical (wavelength) routing and minimizing electronic routing. Recently, there have been effor...
متن کاملClustering techniques for traffic grooming in optical WDM mesh networks
In WDM msmission, each data channel is carried on a unique wavelength (or optical fnquency) and a single optical fiber has many different wavelengths. A lightpath (wavelength continuous path without processing in intermediate nodes) is needed to set up for an end-bend transmission Because of the lightpath continuity constraint, we need to consider the routing as well as pick up appropriate wave...
