Fault recovery techniques must be reexamined in the light of the new guaranteed
performance services that high-speed packet/cell switched networks will support. We …

For several real-time applications it is critical that the failure of a network component does
not lead to unexpected termination or long disruption of service. In this paper, we propose a …

This article addresses key issues related to the administration of ATM backbones based on
virtual paths with embedded restoration capabilities. The concept of logical subnetworking …

The state-independent (SI) and state-dependent (SD) path restoration schemes for self-
healing networks are studied in this paper. The integer programming (IP) formulations for the …

We first present a heuristic algorithm which is based on the minimum cost route concept for
capacity allocation and flow assignment in self-healing networks, and show via numerical …

This paper presents two distinct methods of enhancing the restorability of ATM virtual path
(VP) networks whereby working paths have statically assigned protection or “backup” paths …

The accelerating deployment of high bandwidth fiber optic transmission facilities in
telecommunication and local area networks has increased the potential impact of network …
