Performance parameters evaluation in broadband access network

This paper presents an analytical model for studying the average packet delay in optical access network based on GEPON (Gigabit Ethernet Passive Optical Network) technology. Packet delay is calculated by the use of queuing theory. At the stage of network planning, mathematical modeling techniques based on analytical models and methods of queuing theory may be used to predict the quality of service of the designed network. The indicators of quality of service are the average network packet delay and its variation (jitter). This paper proposes bounded Pareto distribution for traffic flow modeling, and a method for delay analysis based on the Kramer and Langenbach-Belz approximation. The results show that the propagation delay exceeds the queuing delay and it is the main component of the delay.
