Method for bandwidth management by resizing pipes
First Claim
Patent Images
1. 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;
partitioning network bandwidth between the call flows and other classes of traffic; and
scheduling the call flows with priority over the other classes of trafficwherein the call flows are aggregated into a pipe across a backbone of the network; and
wherein the pipe is resized on a periodic basis.

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.

2. 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 egress router. - View Dependent Claims (3)

4. 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 the request being transmitted on a same path as the call flow; 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. - View Dependent Claims (5)

6. 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, the request being transmitted on a same path as the call flow; wherein the requesting bandwidth step further comprises forwarding a message through the core routers without the message being interpreted by the core routers.
