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.

In recent years, most of attention has been given on the
Traffic Grooming, Routing and wavelength assignment
schemes, as it is very crucial factor of the Optical
Network. Many researchers have worked on Sparse
Traffic Grooming in order to minimize the Blocking
probability of the network ultimately it improves the
performance as well. In this paper I have tried to
summarize various techniques used for sparse traffic
grooming and RWA schemes in optical network.
