  • responsive to receipt of an admission request, identifying a source gateway and a destination gateway;

    updating cost data associated with the network links by performing traffic measurements by traffic class at the IP routers, and reporting the traffic measurements with traffic measurement reports;

    from the updated link cost data, determining costs associated with various paths through the network;

    selecting a most favored pair of forward and reverse paths between the source gateway and the destination gateway having the minimum cost;

    comparing cost data associated with the selected paths and a threshold value; and

    , based on the comparison, selectively blocking the packet stream.
