Flow based networking can assist in addressing current performance issues in convergent IP networks and enable dynamic, real-time routing. The Scheme for Advanced Overflow Routing (SAPOR) is a method that enables flow based routing in IP networks. This paper presents an analytical model that allows the calculation of overflow probabilities for flows, transmitted via a bottleneck connection. The proposed model is verified by simulation and results are presented. Similar to the Erlang B formula, the proposed model can be used as a generic multi-rate blocking model, i.e. when call rates (required resources) are drawn from probability distributions. Examples include ATM and GSM networks.
