A Programmable Switch Architecture For Achieving Flexible Quality Of Service
نویسندگان
چکیده
This paper describes a programmable switch architecture that can be dynamically tuned to support flexible quality of service metrics for flows in the Internet. The switch architecture consists of six key components: scheduling, flow aggregation, queueing, packet-level admission control, packet dropping, and feedback. We show that it is possible to achieve a wide range of QoS behavior ranging from strict per-flow rate and delay guarantees to coarse per-class rate assurances by programming the components appropriately.

Interfaces for Open Programmable Routers
The ability to rapidly create and deploy new network services and architectures in response to new user demands is a driving force behind the emergence of programmable networks. The goal of open network control is being addressed in the IEEE P1520 Working Group (http://www.ieee-pin.org/) through the definition of a set of open network programming interfaces for networks. In this paper, we discu...
متن کاملA software radio architecture for linear multiuser detection
The integration of multimedia services over wireless channels calls for provision of variable quality of service (QoS) requirements. While radio resource management algorithms (such as power control and call admission control) can provide certain levels of variability in QoS, an alternate approach is to use reconngurable radio architectures to provide diverse QoS guarantees. In this paper, we o...
