Abstract: A method and apparatus for providing call admission control in a packet network such as an internet protocol (IP) network are provided. More particularly, a terminating endpoint of a logical connection on a packet network, e.g. an IP network, is provided with the ability to make a decision on whether to accept or reject an incoming call based on quality of service (QoS) indicator based on QoS metrics. These metrics indicate quality of service levels for specific logical connections and are accumulated over specified time periods.

Abstract: A telecommunication system includes edge switches and a transmission system that interconnects the edge switches. The transmission system includes a plurality of layered transmission networks. Communication channels connect each edge switch to at least a first of the layered transmission networks. Further, a method provides traffic routing in a telecommunication system having ordered, layered transmission networks, the originating and terminating edge switches to carry a new requested traffic are identified. The highest order layered transmission network connecting the originating and terminating edge switches that is available to carry the traffic is determined. The determined highest order layered transmission network to carry the traffic is assigned to carry the traffic.
