Automated and Scalable QoS Control for Network Convergence
摘要:
Network convergence is becoming increasingly im- portant for cost reduction and management simplifica- tion. However, this convergence requires strict perfor- mance isolation while keeping fine-grained control of each service (e.g. VoIP, video conference etc.). It is diffi- cult to guarantee the performance requirements for vari- ous services with manual configuration of the Quality-of- Service (QoS) knobs on a per-device basis as is prevalent today. We propose a network QoS control framework for converged fabrics that automatically and flexibly pro- grams a network of devices with the necessary QoS pa- rameters, derived from a high level set of application re- quirements. The controller leverages our QoS extensions of OpenFlow APIs, including per-flow rate-limiters and dynamic priority assignment. We also present some re- sults from a testbed implementation to validate the per- formance of our controller.
