Optical networks are moving from opaque and translucent architectures towards all-optical
(transparent) architectures. In translucent architectures a small amount of regeneration (eg …

Since light-paths are the basic connections in wavelength routed networks, their effective
establishment is very important. Routing and Wavelength Assignment (RWA) techniques …

With the ever-increasing traffic demands, the infrastructure of current 10 Gbit/s optical
network needs to be enhanced. The legacy infrastructure can be enhanced not only by …

In WDM all-optical networks where electrical regeneration is not available, physical
impairments due to propagation in the fibers, amplifier noise, and leaks between channels …

In transparent DWDM (Dense Wavelength Division Multiplexing) networks, high blocking
rate of lightpaths due to unsatisfactory BERs (Bit Error Rates) can become a major traffic …

In all-optical networks with no wavelength conversion, signals must travel on the same
wavelength over possibly very long distances. During transmission, the QoS of signals as …

In all-optical WDM networks, feasibility of a lightpath are determined by physical layer
impairment accumulation. Physical layer impairment-aware routing and wavelength …

This paper proposes and evaluates a four-wave mixing (FWM) aware evolutionary
programming algorithm for dynamically setting up lightpaths in an optical wavelength …

Soft failure with lower optical signal-to-noise ratio (OSNR) might reduce the quality of the
supported services. When the soft failure is detected, the affected existing lightpaths are …

A quality-of-transmission-(QoT-) aware routing and wavelength assignment (RWA)
technique suitable for multifiber wavelength-routed all-optical networks supporting class …
