Abstract:
For network service providers, assessing and monitoring network parameters according to a Service Level Agreement (SLA) as well as optimal usage of resources are important. Packet loss is one of the main factors to be monitored especially when IP networks carry multimedia applications. Measuring network parameters will be more valuable when it is accurate and online. In this paper, we investigate a method to estimate packet loss probability (plp) under several conditions and improve the quality of the estimation over established techniques by introducing a new formula. In this method, the estimation of the plp in the intermediate nodes is based on the input stochastic traffic process. Different traffic situations and node buffer sizes are simulated by NS-2 and the accuracy of the method is investigated. The simulation results show that our new formula significantly improves the quality of the plp estimate.
