RWA for Network Virtualization in Optical WDM Networks
Qiong Zhang, Weisheng Xie, Qingya She, Xi Wang, Paparao Palacharla, Motoyoshi Sekiya · 2013
We jointly consider problems of virtual network mapping and routing and wavelength assignment in WDM networks. Flexible virtual node mapping enabled by network virtualization achieves significant optical network resource savings compared to fixed node mapping.
