Integrated methodology for supporting packet network performance management and planning

Abstract

This paper describes an integrated approach for supporting packet network performance management and planning. As more and more packet networks — such as the public packet switched networks, common channel signalling networks and metropolitan area networks — are being deployed in the Regional Bell Operating Companies, new network operations systems are required for planning the evolution and engineering the service performance of these traffic-sensitive packet networks. This paper describes some of the synthesis and analysis algorithms that we have designed for supporting the traffic engineering of a public packet switched network. The synthesis algorithms include network element sizing, processor load balancing, network layer window size adjustment and traffic rerouting. The analysis algorithms include network element utilization and delay estimation as well as network end-to-end delay estimation.
