[TuG3-2] Numerical Analysis of Adaptive Restoration in Optical Transport Networks

〇Masahiro Nakagawa, Hiroki Kawahara, Kana Masumoto, Hidetoshi Onda, Kazuyuki Matsumura (NTT Corporation, Japan)

Keywords:Rapidly reconfigurable switching networks including Wavelength (spectrum) routing and assignment for wavelength-switched optical networks

We clarify the benefits of an adaptive restoration scheme for the highly-available optical layer. Simulations verify that 80%+ of double-link failures can be recovered and 80%+ of traffic can be restored on several realistic topologies.
