Failure protection and restoration is gaining significance as high capacity optical networks
become increasingly ubiquitous. An important design issue that faces the network operator …

In the protection scheme of fault management in a WDM optical network, corresponding to
every source‐destination path used for data transmission, a backup path is maintained in a …

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 the problem of establishing dependable connections in WDM networks with
dynamic traffic demands. We call a connection with fault-tolerant requirements a …

Resilient optical networks are predominately designed to protect against single failures of
fiber links. But in larger networks, operators also see dual failures. As the capacity was …

This paper considers the problem of dynamically establishing dependable connections (D-
connections) with specified failure restoration guarantees in wavelength-routed wavelength …

Link recovery in high-speed four-fiber networks can be achieved using dynamic searches,
covers of rings, or generalized loopback. We present a method to provide link recovery for …

This investigation considers optical networks which employ wavelength cross-connects that
enable the establishment of wavelength-division-multiplexed (WDM) channels, between …
