By moving the admission control process to core nodes, which have the most updated information about their own traffic conditions, these schemes can provide reliable and robust per-link loss guarantees. However, the issue of how to provide edge-to-edge guarantees for burst flows over the entire edge-to-edge paths have not been investigated in any of the proposals. In this paper, we propose a signalling and reservation scheme to coordinate the reservation and teardown process over the edge-to-edge path in the absolute QoS model. The key idea is to judiciously divide the edge-to-edge loss requirement into a series of small loss probabilities that are allocated to the intermediate links. The performance of the scheme is evaluated through simulation. © 2004 IEEE.||Source Title:||GLOBECOM - IEEE Global Telecommunications Conference||URI:||http://scholarbank.nus.edu.sg/handle/10635/69136|
