En Route to Grouping-Constraint Free,Colorless Directionless ROADMs
Networks Optical Communications All-Optical Networks
2015/6/5
WSS-based ROADM architecture limits local transponder wavelengths to a grouping constraint.3D-switch-based architecture offers powerful solution without grouping constraint. This paper presents an upd...
A Scalable Constraint-based Path Computation Approach in Multi-domain Optical Networks
Networks Optical communications
2015/6/4
Inter-domain network information distribution becomes the bottleneck of constraint-based path computation in multi-domain optical networks. This article proposes scalable DHT-based path computation ap...
Optical Multicast Tree Construction Algorithm Considering SNR Constraint and 3R Regeneration
Optical Multicast Construction Algorithm SNR Constraint Regeneration
2015/8/3
We propose a novel multicast tree construction algorithm for video distribution/multicasting. The algorithm successfully handles the optical signal impairments caused by transmission and branching, an...
