چکیده

Traffic Grooming has become a very important issue on optical Network, as optical networks provide a very high speed data transmission for huge amount of data. A Sparse grooming Network with only a fractional of nodes having grooming functionalities may achieve the same performance as the one in which all the nodes are grooming, but with much lower cost. In literature different algorithms, models and techniques have been proposed to design the sparse grooming networks. With Proper assignment of routing and wavelengths in the network reduces the blocking probability ultimately increases the bandwidth of the network. In this paper, we studied and analyzed the different sparse traffic grooming and RWA assignment strategies with its performance metrics for optical mesh networks.

Traffic grooming, routing, and wavelength assignment in WDM transport networks with sparse grooming resources

While a single fiber strand in wavelength division multiplexing (WDM) has over a terabit-per-second bandwidth and a wavelength channel has over a gigabit-per-second transmission speed, the network may still be required to support traffic requests at rates that are lower than the full wavelength capacity. To avoid assigning an entire lightpath to a small request, many researchers have looked at ...

A Novel Protection Guaranteed, Quality of Transmission Aware Routing and Wavelength Assignment Algorithm for All-optical Networks

Transparent All Optical Networks carry huge traffic and any link failure can cause the loss of gigabits of data; hence protection and its guarantee becomes necessary at the time of failure. Many protection schemes were presented in the literature, but none of them speaks about protection guarantee. Also, in all optical networks, due to absence of  regeneration capabilities, the physical layer i...

Dynamic Traffic Grooming using Fixed-Alternate Routing in WDM Mesh Optical Networks

There is a mismatch between lightpath channel capacity and traffic request capacity in wavelength division multiplexed (WDM) optical mesh networks. Traffic grooming is needed to resolve this mismatch in an efficient way. We study the dynamic traffic grooming problem in WDM mesh networks using the fixed-alternate routing (FAR) approach. Based on the FAR approach, we propose the fixed-order groom...

Traffic Grooming in Optical Networks: Decomposition and Partial LP Relaxation

We consider the traffic grooming problem, a fundamental network design problem in optical networks. We first review a typical ILP formulation considered in the literature, and we identify two challenges related to this formulation in terms of scalability and wavelengths fragmentation. We then propose a new solution approach that decomposes the traffic grooming problem into two subproblems that ...

Traffic Grooming Optimization in Mesh Wdm Networks without Wavelength Converter

This is a tutorial paper on the traffic grooming optimization in mesh Wavelength Division Multiplexing (WDM) networks for static traffic patterns. The traffic grooming technique provides a two-layer traffic engineering capability by aggregating and routing low-bandwidth traffic flows from the upper layer over re-configurable highbandwidth connections in the lower layer. This paper demonstrates ...
