Maximizing Profits of Routing in WDM Networks

Let G = (V, E) be a ring (or chain) network representing an optical wavelength division multiplexing (WDM) network with k channels, where each edge e j has an integer capacity c j . A request {si , ti} is a pair of two nodes in G. Given m requests {si , ti}, i = 1, 2, . . . , m, each with a profit value pi , we would like to design/route a k-colorable set of paths for some (may not be all) of t...

Dynamic routing at different layers in IP-over-WDM networks - Maximizing energy savings

We estimate potential energy savings in IP-over-WDM networks achieved by switching off router line cards in low-demand hours. We compare three approaches to react on dynamics in the IP traffic over time, FUFL, DUFL and DUDL. They provide different levels of freedom in adjusting the routing of lightpaths in the WDM layer and the routing of demands in the IP layer. Using MILP models based on thre...

Dynamic Routing in Survivable WDM Networks

Changing trends in backbone transport networks towards dynamic path provisioning and evolving optical technologies have motivated the study of dynamic routing algorithms in the context of Multi Protocol Label Switching (MPLS) based networks. As the network size increases, it is impractical to maintain detailed information regarding every connection that is established in the network. Hence, rou...

Multimedia Traffic Routing in Multilayer WDM Networks

The advent of real-time multimedia services over the Internet has stimulated new technologies for expanding the information carrying capacity of optical network backbones. Multilayer wavelength division multiplexing (WDM) packet switching is an emerging technology for increasing the bandwidth of optical networks. Two algorithms for the routing of the multimedia traffic flows were applied: (i) C...

Dynamic routing in translucent WDM optical networks

Translucent WDM optical networks use sparse placement of regenerators to overcome the impairments and wavelength contention introduced by fully transparent networks, and achieve a performance close to fully opaque networks with much less cost. Our previous study proved the feasibility of translucent networks using sparse regeneration technique. We addressed the placement of regenerators based o...
