Modeling the performance of low latency queueing for emergency telecommunications
Event simulation and analytic modeling are used to evaluate the performance of Low Latency Queueing (LLQ), a queueing discipline available in some Internet packet switching routers for integrated services performance assurance. LLQ combines priority queueing with ClassBased Weighted Fair Queueing (CBWFQ). Priority queueing is used to ensure satisfying tight delay constraints for real-time traffic, whereas CBWFQ is used to ensure acceptable throughput for traffic classes that are less sensitive to delay. Simulations are developed both using a commercial product, OPNET Modeler, and also custom simulators that we developed. Our custom simulators model two different approaches to CBWFQ; and comparisons between the approaches and that of the commercial simulator are conducted. Our computational experiences (central processing unit [CPU] times for model execution and postprocessing) in using the simulators are described. This work is an important first step in the ability to model a propose...
