A New Multicast Wavelength Assignment Algorithm in Wavelength-Converted Optical Networks

A New Multicast Wavelength Assignment Algorithm in Wavelength-Converted Optical Networks

In this paper, we propose a new multicast wavelength assignment algorithm called NGWA with complexity of O(N), where N is the number of nodes on a multicast tree. The whole procedure of NGWA algorithm is separated into two phases: the partial wavelength assignment phase and the complete wavelength assignment phase. It tries to minimize the total number of wavelength conversions of the multicast...

A Novel Protection Guaranteed, Quality of Transmission Aware Routing and Wavelength Assignment Algorithm for All-optical Networks

Transparent All Optical Networks carry huge traffic and any link failure can cause the loss of gigabits of data; hence protection and its guarantee becomes necessary at the time of failure. Many protection schemes were presented in the literature, but none of them speaks about protection guarantee. Also, in all optical networks, due to absence of  regeneration capabilities, the physical layer i...

CoS-oriented Wavelength Assignment Algorithm in Burst Switching Optical Networks

We present a CoS-oriented wavelength assignment algorithm for burst switching optical networks with multiple service classes. Simulation results show that CoS is realized in terms of burst blocking probability and throughput.

Distributed Wavelength Assignment Algorithm for Optical Bursts in WDM Networks

We present a distributed wavelength assignment algorithm named Priority-based Wavelength Assignment (PWA) for the contention resolution problem in buffer-less burst optical networks without wavelength conversion capability. Simulation results show that the PWA can effectively reduce the blocking probability and increase the performance of burst optical networks compared to previous algorithms s...
