Virtual path self-healing scheme based on multi-reliability ATM network concept

This paper proposes a new self-healing concept for ATM networks: multi-reliability self-healing. First, we show the necessity of multi-reliability self-healing in the future B-ISDN era, and propose a multi-reliability virtual path (VP) network concept achieved through multi-reliability self-healing. Next, we propose a new self-healing scheme based on the multi-reliability VP network by extending the existing self-healing scheme. Finally, evaluations confirm the effectiveness of the proposed scheme and the feasibility of multi-reliability VP networks.
