Comparison of optical inter-domain routing protocols in the presence of wavelength converters

The success of optical technology has introduced a new future for the Internet. With the many advantages of optical technology, multimedia applications which require strict quality of service(QoS) are able to be guaranteed in an optical network. Unfortunately, the optical technology still have some limits in setting up a connection. One of these...

Impairment-Aware QoS Routing in Translucent Optical Networks

Wavelength-division-multiplexed (WDM) optical networks are commonly used to trans- port huge amount of tra±c in long-haul and metro/regional networks. In these networks, the optical signals deteriorate due to the physical impairments they encounter as they traverse multiple links. This necessitates regeneration of the signals at the intermediate...

Diverse routing in SRLG networks

As our dependency on communication increases so is the demand for protecting these communication lines. To provide failure-safe connections in optical networks, lightpaths can be protected. Protected lightpaths consist of a primary path and a backup path which are disjoint and ensure connection continuity in case of a single link failure....
