Quality of service support over switched Ethernet
Anil Kumar Pandey, Hussein Alnuweiri · 2003
This paper investigates the performance of switched-Ethernet LANs when transporting real-time video streams. Our study covers several switched-LAN topologies that employ switches with different capabilities. Such capabilities include the use of shared versus dedicated ports and single versus multi-priority access buffers in the switch ports. As an example, we consider the transport of several medium and low packet video streams that correspond to video conferencing activities over a switched LAN. Our results show the impact of LAN switch parameters on the delay and loss performance of real-time video streams.
