Scalable Communication for High Performance and Inexpensive Reliable Strict QoS

Abstract

Traffic that requires high service quality often uses a single path with reserved resources for data transmission. The use of a single dedicated path suffers from single link failures. This paper provides a solution (TPmax-S) that uses scalable routing information to find alternate paths in the event of a single link failure in the network. When such a failure occurs, a flow that requires a path with reserved resources has a high rate of successfully finding enough resources on the backup path computed by TPmax-S, and thereby maintains continuous, high quality service to the user. This reliable high quality service can be provided without reserving more resources prior to the failure, and hence is an inexpensive solution to offer a better service. In this paper, initial tests are performed on TPmax-S and other similar backup path computation methods. These initial results show that TPmax-S provides very good backup paths while using scalable communication overhead
