- Abstract
Distributed real-time applications such as medical imaging, traffic control, and video conferencing demand hard guarantees on the message delivery latency and the recovery delay from component failures. In order to meet these requirements there exist number of schemes by reserving additional resources a priori along a backup channel which is disjoint with the primary path. A new method has been proposed for computing segmented backup for recovering from node and link failures in real-time IP communications. This paper compares the performance of proposed scheme with the schemes available in the literature for mesh and other topologies. It has been demonstrated that the proposed scheme gives better results on parameters like number of backup segments, percentage reuse of primary path and average hop count for failure notification.
