Abstract
Signaling messages are exchanged for a call between a calling party to a called party. A setup message for the call is exchanged through at least one gate controller. Network resources are reserved for the call based on the exchanged setup messages. An end-to-end message for the call is exchanged without the end-to-end message being routed through the at least one gate controller.
Claims2
A method for allocating network resources for a plurality of calls between calling parties and called parties comprising:
- aggregating call flows into a single queue and
- partitioning network bandwidth between the call flows and other classes of traffic;
- wherein the call flows are aggregated into a pipe across a backbone of the network;
- and
- wherein the pipe is resized on a periodic basis.
A method for allocating network resources for a call between a calling party and a called party comprising:
- receiving a reservation request for the call flow at an ingress aggregation router connected to an egress router by a pipe across a plurality of core routers in a core network;
- and
- requesting bandwidth for the call flow to an egress aggregation router;
- wherein the requesting bandwidth step further comprises the steps of:
- modifying the reservation request to hide it from core routers;
- forwarding the reservation request across the core network to the aggregation network;
- receiving the reservation request at an egress aggregation router;
- checking to see if the flow can be accommodated on the pipe between the ingress aggregation router and the egress aggregation router.
