Because of their high flexibility, ATM networks have the potential to achieve two objectives:
switch cost reduction and multi-level network availability. For that purpose, this article …

Future networks must offer extremely high levels of reliability because information has
become critical to the continued well-being of society. This article shows the approaches to …

Fast restoration from a network failure has been recognized as a key ingredient in realizing
survivable networks in emerging high-speed ATM environments. Self-healing techniques …

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 …

In this paper, we propose a fast restoration mechanism for virtual path-based ATM networks.
Given an ATM network topology, the capacity of each physical link, and the primary virtual …

In this paper, we propose a new design method to construct the highly reliable ATM network
based on the virtual path (VP) concept. Through our method, we can guarantee a network …

In self-healing networks, end-to-end restoration schemes have been considered more
advantageous than line restoration schemes because of a possible cost reduction of the …

Dynamic restoration for ATM virtual path is an important network management function for
survivable ATM networks. In the multiple-layer survivability architecture, the dynamic …

This paper presents a reconfiguration scheme resulting in capacity efficiency and fast
restoration by utilizing the inherent benefits of Virtual Paths in ATM networks. The unified …

The advent of high-capacity optical fiber has increased the impact of a network failure in
high-speed networks since a large volume of data can be lost even in a short outage. Self …
