1. A method of admitting calls over a network, comprising:

  • receiving a call request to establish a call, the call request defining a throughput requirement and comprising an origination address for identifying an origination terminal and an identifier for identifying a destination terminal;

    transmitting a throughput measurement request in response to the received call request, the throughput measurement request causing a trace to propagate via a path between the origination terminal and the destination terminal;

    in response to the trace, receiving information identifying one or more network resources on the path between the origination terminal and the destination terminal;

    monitoring one or more performance characteristics of the one or more network resources identified to generate a throughput measurement of the path; and

    transmitting a call admission response to the origination terminal when the throughput measurement at least substantially matches the throughput requirement of the call request.
