Resum
Sliceable bandwidth-variable transponders (SBVTs) enable the adaptation of transmission parameters according to traffic requirements and network constraints. In this study, SBVTs capabilities are evaluated in the context of restoration. In particular, multipath recovery and bitrate squeezing are applied to maximize the amount of restored bitrate, also exploiting limited portions of spectrum resources along multiple routes. An integer linear programming model and heuristic strategy are proposed. ...
