Quality of service (QoS) analysis of an Internet traffic trace over gigabit Ethernet

An Internet traffic trace over gigabit Ethernet contains information on arrival time and size of every packet over the collection period. An important problem is to model the latency and packet losses within the trace. The Lindley equation is a general form of describing the evolution of queueing delay processes and queue length processes, both of which are tightly associated with the latency and packet losses. We report on our use of the Lindley equation to analyse publicly-available link-layer data from a gigabit Ethernet gateway and discuss the performance of packet queueing delay and queue length based on the data.
