Abstract

We have developed a closed equation that allows calculation of the optimal bandwidth based on estimates of volume and quality of service criteria of user traffic. The basic assumption underlying the equation is that traffic to be dropped at a bottleneck link should not be sent to that link in the first place. Instead, such traffic should be dropped as early as possible. The equation was validated with simulations using a topology and a traffic mix typical for 3G radio access networks. The quality of service of user traffic to the routers on either side of the backup link was considerably better compared to standard methods. The equation uses only a few parameters based on the traffic demand matrix and is easily incorporated in a network-planning tool to calculate backup links or bandwidth requirements for logical pipes. It can also be used as basis for complete network planning.
