Network virtualization is critical for distributing cloud services over expanded distances and improving scalability and responsiveness. However many providers are very concerned about maintaining high availability, particularly under large catastrophic/disaster type conditions causing multiple failures. Now recent studies have looked at network virtualization for disaster recovery. However these...
The primary objective of designing the hand exoskeleton is to include a controllable degree of freedom (D.O.F) of the finger joints with minimum number of actuation modes. This paper describes the design and development of a multi D.O.F. hand-exoskeleton based on the rehabilitation criteria of an amputee to achieve different hand gestures on the passive amputee hand. The design contains 3 D.O.F finger...
A novel multi-domain path routing solution is proposed for improving connection reliability under multiple correlated failure events. The formulation assumes probabilistic failures and jointly incorporates traffic engineering objectives.
This paper addresses multi-domain lightpath provisioning within the context of correlated multi-failure events. The work jointly incorporates both risk minimization and traffic engineering objectives, and develops a novel graph theoretic scheme for distributed operation in realistic optical network settings. Detailed performance evaluation results are then presented to gauge the effectiveness of the...
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...
