An Initial Occupancy Based Router Policy Ensuring Better QOS for Real Time Data Transfers

Authors : Jyothish K. John and R. V. Siva Balan

Abstract: Forwarding and delivery in internet is not guaranteed and it is a best-effort service. Real-time data transfers which have deadlines on various Quality of Service (QOS) parameters may suffer from severe problems of throughput and delay while getting transferred through internet. This can be overcome either by a scheduling mechanism or by a dropping policy which help the real-time data transfers achieve their QOS requirements without keeping a bias against non-real-time data flows. There are many active queue management policies and dedicated queuing mechanisms trying to bring fairness for flows which may also promote real-time data transfers indirectly but may not be sufficient to satisfy their deadlines of throughput and delay. Active queue management policies like RED based schemes try to bring general fairness by allocating bandwidth fairly to all the flows but even such schemes cannot provide a fair treatment to real-time flows which send small sized packets at regular intervals. The study proposes adropping policy which differentiate real-time data transfers and promote them to correct extend without denyingdeserving quality for non-real-time traffic. The experimental results prove that the new dropping policy, fair RED can promote real-time data transfers approximately to a correct extend without causing a bias against non-real-time transfers.
