A design of self-healing ATM networks based on backup virtual paths

Chae Y. Lee, Seok J. Koh
1998 Computers & Operations Research  
A backup VP can be assigned between any pair of nodes on a VP route. The backup route is link disjoint from the original path to avoid the simultaneous failure of both the original and the backup VP.  ...  Abstracts We propose a design of self-healing ATM virtual path (VP) networks based on backup VP. The backup VP is a preassigned virtual path to restore the traffic after a network failure.  ...  If those target VPs are link disjoint in the network, the network cost is reduced by routing those corresponding two backup VPs through a common path.

A New Approach to Survivability of Connection Oriented Networks [chapter]

Krzysztof Walkowiak
2003 Lecture Notes in Computer Science  
In this paper we concentrate on survivability of connection oriented networks (ATM, MPLS, Frame Relay). We introduce a new approach to network survivability.  ...  Issues of network reliability are very important in modern computer networks. Even a short failure of a network link can cause substantial consequences.  ...  Each connection, i.e. virtual path in ATM or label switched path in MPLS, has a primary route and a backup route.  ...
