Dynamic End-to-End QoS Management for Advanced RF Telemetry Networks

Abstract

We present iMANPOL - a dynamic end-to-end QoS management system for advanced RF telemetry networks with the red-black separation constraints. iMANPOL system encompasses network resource monitoring, allocation, and enforcement techniques to increase throughput and reduce end-to-end delay of telemetry traffic while protecting priority mission-critical flows. These goals are achieved through adaptive techniques for providing Differentiated Services, Admission Control Function, and Flow Preemption. The iMANPOL system has been implemented and tested in an emulated environment. The test results confirm that the admission control, particularly when coupled with preemption, can significantly increase the performance of priority flows in congested networks. An iMANPOL deployment in the integrated enhanced network telemetry would make more network resources available for high-priority tests and enable more dynamic test scheduling.
