Dynamic Routing and Spectrum Assignment in Flexible Optical Path Networks
Dynamic Routing Flexible Optical Path Network Spectrum Assignment
2015/5/15
We propose dynamic routing and spectrum assignment algorithms for bitrate-flexible lightpaths in OFDM-based optical networks. The novel algorithms enable dynamic spectrum assignment with more efficien...
On the Spectrum-Efficiency of Bandwidth-Variable Optical OFDM Transport Networks
Spectrum-Efficiency Bandwidth-Variable Optical OFDM Transport Networks
2015/6/10
We investigated the high spectrum efficiency property of the bandwidth-variable optical OFDM (BV-OOFDM) transport networks. In contrast to mixed-line-rate (MLR) networks, BV-OOFDM enables flexible all...
