This paper studies reconfiguration design for cloud-based virtual network services mapped over optical substrates. A novel scheme is proposed to improve resource efficiency and its results are analyzed versus some existing strategies.
This paper develops a novel hierarchical optimization model for lightpath protection in multi-domain optical networks pursuant to several objectives. The proposed formulation is then solved and its results compared with some advanced distributed heuristic protection strategies.
Multi-domain optical network provisioning is a key focus area asusers continue todemand scalable bandwidth services across wider network regions. To date, a range of distributed schemes have been proposed to achieve lightpath routing across domain boundaries. In general, these solutions rely upon hierarchical routing and provisioning strategies and are mostly heuristics based. As such, it is difficult...
Multi-domain networking is an important focus area and crankback signaling strategies offer much potential for post-fault recovery. However, most studies in this space have not addressed multi-failure scenarios, e.g., correlated failures such as those resulting from weapons of mass destruction attacks. Hence this paper proposes a novel solution for intra/inter-domain post-fault crankback restoration...
