An analysis of the applicability of the TFD IP option for QoS assurance of multiple video streams in a congested network

Abstract

The Trafïîc Flow Description (TFD) option is an experimental option of the IP protocol, designed by the Authors, able to assure signaling for QoS purposes. The option is used as a carrier of knowledge about forthcoming traffic. If planning horizons are short enough, this knowledge can be used for dynamic bandwidth allocation. In the paper an analysis of QoS assurance using the TFD option is presented The analysis was made for a case of QoS protection of multiple video streams. Results show that dynamic bandwidth allocation using the TFD option gives better QoS-related parameters than the typical approach to QoS assurance, based on the RSVP protocol.
