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

Abstract

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 linklayer data from a gigabit Ethernet gateway and discuss the performance of packet queueing delay and queue length based on the data.

QoS management for performance analysis of switched Ethernet networks

“…To address the need for real-time networked embedded systems to be adaptable, dynamic, and have efficient resource allocation, two methods have been proposed. The first, known as Flexible Time-Triggered Switched Ethernet (FTT-SE) [11], was designed to work with commercial off-the-shelf (COTS) Ethernet switches, while the second, known as Hard Real-Time Ethernet Switching architecture (HaRTES) [12] [13], makes use of specially equipped Ethernet hubs. The master-slave approach lies at the foundation of both suggested systems, which were first developed for a network with a single switch.…”
