ABSTRACT
The demand for bandwidth is growing at a rapid pace, and the Internet data traffic is
expected to dominate voice traffic in the near future. With the Internet Protocol (IP)
playing a dominant role in wide area networking technology and advancements in
wavelength division multiplexing (WDM) technology to provide enormous bandwidth over
and above the range of Tera bits per second, the IP-over-WDM networks become the right
choice for the next generation Internet networks. Recently Virtual Topology
Reconfiguration of IP over WDM networks has received greater attention among
researchers. This paper researches the various approaches available in the literature for
Virtual Topology Reconfiguration problem with Traffic Grooming for IP-over-WDM
networks.
