We present a review of the integer linear programming (ILP) formulations that have been
proposed for the routing and wavelength assignment problem in WDM optical networks …

Survivability, the ability of a network to withstand and recover from failures, is one of the most
important requirements of networks. Its importance is magnified in fiber optic networks with …

Network restoration is often done at the electronic layer by rerouting traffic along a
redundant path. With wavelength-division multiplexing (WDM) as the underlying physical …

We consider an IP-over-WDM network in which network nodes employ optical
crossconnects and IP routers. Nodes are connected by fibers to form a mesh topology. Any …

The exponentially growing number of Internet users armed with emerging multimedia
Internet applications is continuously thirsty for more network capacity. Wavelength-division …

This study investigates the problem of fault management in a wavelength-division
multiplexing (WDM)-based optical mesh network in which failures occur due to fiber cuts. In …

This paper investigates survivable lightpath provisioning and fast protection switching for
generic mesh-based optical networks employing wavelength-division multiplexing (WDM) …

Network restoration is often done at the electronic layer by rerouting traffic along a
redundant path. With wavelength division multiplexing (WDM) as the underlying physical …

The advent of fiber optic transmission systems and wavelength division multiplexing (WDM)
have led to a dramatic increase in the usable bandwidth of single fiber systems. This book …

Transport networks evolved from DCS (Digital Cross-connect Systems)-based mesh
architectures, to SONET/SDH (Synchronous Optical Networking/Synchronous Digital …
