A New Adaptive Fair Queueing (AFQ) Scheduler for Support SLA

Abstract

Providing Quality of Service in the Internet is a complex and multilevel problem involving heterogeneous media, protocols and technologies. The ability to differentiate traffic will allow introducing QoS oriented business relationships and pricing models, supported by the establishment of Service Level Agreements (SLAs.) Recent developments within the research community and within commercial products provide numerous technologies that may be applied as solutions. In this paper we are proposing the new adaptive (AFQ) scheduling for SLA QoS management model for differentiated services , reasoned by the virtual queue and dynamic weighted queues service coefficient φ, changing according to the evaluation of the packet state in the node, reasoned by delay target time and present network load.

Performance evaluation of opportunistic schedulers based on fairness and throughput in new-generation mobile networks

“…With Fair Queuing (FQ) [1], [6], [7], [8] for a possible link of rate D, each active user K will be served at the height of D/K. Fair Queuing is fairer than the Round Robin since it ensures the same throughput for each user.…”
