Although Software-Defined Networking and its implementation OpenFlow facilitate managing networks and enable dynamic network configuration, recovering from network failures in a timely manner remains non-trivial. The process of (a) detecting the failure, (b) communicating it to the controller and (c) recomputing the new shortest paths may result in an unacceptably long recovery time. In this paper,...
While optimization models for traffic engineering in multi-service networks are known, survivability is a key issue not introduced so far in consideration in such models. In this paper, the novelty and contribution is that new optimization models that address the off-line survivability-supported Traffic Engineering (TE) problem in multi-service networks are presented. In such networks traffic demands...
