A new service differentiation scheme: Size based treatment
Stylianos Dimitriou, Vassilis Tsaoussidis · 2008
The increase of real-time applications as well as the vast usage of portable wireless devices has led to a corresponding increase of real-time traffic with strict bandwidth and delay requirements. In order to satisfy the requirements of various applications we typically use service differentiation. However, as new real-time applications are created, their portion of the total traffic increases, thus making more and more difficult to satisfy completely their requirements. In this paper we propose a new scheme, which is based on the axiom that dasiadifferent types of applications typically utilize different packet sizespsila. With size based treatment (SBT) different packet sizes are dropped with different probability by the queue. Small sized packets can benefit and transmit on higher rates, increasing the total system fairness.
