Minimum cost traffic shaping: a user's perspective on connection admission control

We propose a minimum cost method for traffic shaping in the context of QoS-based networks. Given the user's desired QoS and the network's resource availability, our procedure determines the least-cost parameters for a traffic shaper which still guarantees access to the network whilst satisfying the QoS constraints. We illustrate our scheme using on-off sources and formulate the QoS constraints by effective bandwidths.
