Abstract:
1. A method for measurement-based connection admission control in a packet data network, wherein, in said network, a traffic flow is constituted by the traffic flow of arriving data packets is forwarded via said switch with a delay, the delay depending on the priority of a queue associated to the data packets of a respective connection and the amount of prevailing traffic; the method comprising the steps of: providing an estimated maximal rate envelope (R approximating said envelope to a piecewise linear traffic constraint curve (A(I modifying said piecewise linear traffic constraint curve such that said curve assumes a concave shape; and checking whether a predetermined delay bound for the priority queue of a new connection requesting to be admitted, and the delay bounds for all queues having a lower priority than the requesting new one, are not violated, and granting the requested new connection, if said predetermined delay bounds are not violated.
