A QoS Aware Multicore Hash Scheduler for Network Applications

As the line speed of the network evolves at an unprecedented rate, a wide spectrum of network applications call for increasing processing density on network devices. The prevalence of multicore chips ameliorates the stress on processing power, but the QoS guarantee is often ignored. In addition, results of legacy QoS studies are difficult to apply to multicore web servers. Therefore, a multicore scheduler that incorporates QoS concerns is missing. As the network development moves towards cloud computing, the authors see an increasing importance of QoS guarantees on high performance multicore network appliances.
