Adaptive dual threshold multi-class scheduling for packet switch.

Multimedia applications such as video conferencing, VoIP and data streaming require specified QoS to guarantee their performance. Multi-class switch has been introduced to handle different QoS requirement. In this research, a new way of handling multi-class traffic is presented. The analysis is done...
