PARS: A Predictive Access-Control and Routing Strategy for Real-Time Control of Telecommunication Networks

Traffic control policies devised for the Public Switched Telephone Network (PSTN) of today are based on assumptions of stability, predictability, and homogeneity of the offered traffic. However, the traffic demands on today’s networks are becoming more dynamic and less predictable due to the introduction of a plethora of network services and capabilities. As this trend is expected to continue, we submit that the Integrated Services Networks (ISNs) of the future will have to be controlled in real-time using a closed-loop configuration — much like controlling a dynamical system by state feedback.
