Analytical Modeling for Virtual Topology Reconfiguration for Ip-over-wdm Networks with Qos Parameters Using Gaussian Distribution

Experimental study of dynamic IP topology reconfiguration in IP/WDM networks

With the widespread deployment of IP over WDM networks, it becomes necessary to develop dynamic lightpath and topology reconfiguration mechanisms and reconfiguration triggers that can effectively exploit WDM reconfigurability. A reconfiguration model for overlay IP/WDM networks is introduced. An IP over WDM network testbed has been set up using Telcordia MONET WADMs and IP routers. The testbed ...

Literature Review of Virtual Topology Reconfiguration Problem with Traffic Grooming for IP - over - WDM Networks

Virtual topology reconfiguration in IP/WDM optical ring networks

Wavelength division multiplexing (WDM) has emerged as a promising technology for use in backbone transport networks. In an IP/WDM network, the optical layer provides circuit-switched lightpath services to the client Internet protocol (IP) layer. The set of all the lightpaths in the optical layer defines the virtual topology. Since the optical switches (cross-connects) are reconfigurable, the vi...

MASTER THESIS Energy Efficiency in IP over WDM Networks

In the last decade, energy efficiency in backbone networks has become an important problem due to the significant growth in the Internet traffic. A very promising solution to solve this problem in Internet Protocol (IP) over Wavelength Division Multiplexing (WDM) networks is the Virtual Topology Adaptation approach, which permits adapting network resources by following a dynamic daily traffic p...

Virtual Topology Generation to Minimize the Total Combined Cost in IP over WDM Networks

As the Internet traffic volume increases, the IP over WDM network is expected to be the dominant architecture in future Internet backbone networks. For IP routers to transfer their traffic, the virtual topology should be constructed from lightpaths supplied by WDM networks. To reflect the demand-supply relation of IP and WDM layers, we present the total combined cost as the network design goal ...
