Megaconference: QoS-enabling Megaconference III

Time 10/03/01 04:45PM-06:00PM

Session Abstract

Recent attempts at providing Quality of Service within the Internet2 community have focused primarily on Expedited Forwarding and also make certain assumptions about an application's network requirements. It is important to define Quality of Service (QoS) in terms of hard performance bounds, particularly for visibly sensitive applications such as video conferencing. In addition, H.323 video conferencing, the technology used for this and previous Megaconferences, was developed for a Best Effort network and exhibits certain properties in response to difficult network conditions. In order to "QoS-enable" Megaconference III, ITEC-Ohio and ITEC-NC collaborated to perform H.323 traffic characterization tests and develop an appropriate QoS strategy. This presentation will discuss the results and implications of this approach and show its application to Megaconference III through "QoS-on-now-QoS-off" demonstrations.
