Enhancing the self-healing capability of statically protected ATM networks
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. Since preplanned restorati...

Design and Performance Issues of Protection Virtual Path Networks
This paper addresses the problem of allocating protection Virtual Path (VP) routes in an ATM network to enable rapid restoration from span or node failures. It is shown how the minimisation of one resource, sp...
