Approximation Ratios of Multicast Light-Trees in WDM Networks
Abstract--All-optical multicast routing (AOMR) is implemented by the concept of light-tree in WDM networks. The costoptimal multicast light-tree is NP-hard to compute, especially w...

Efficient Distributed Algorithm for RWA Using Path Protection
A number of Integer Linear Program (ILP) formulations for both static and dynamic lightpath allocation have been proposed, for the design of survivable WDM networks. However, such ...

Dynamic routing and resource allocation in WDM transport networks
This contribution concentrates on dynamic routing in WDM (Wavelength Division Multiplexing) networks. It is shown that a strategy based on precalculated alternatives and an adapti...

Dynamic Wavelength Routing in WDM Networks under Multiple Signal Quality Constraints
—Most research works in routing and design of optical networks assume that the optical medium can carry signals without any bit error. However, the physical impairments on the op...
