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.
