System and method for provisioning flows in a mobile network environment
First Claim
1. A method for provisioning communication flows in a network environment, comprising:
- maintaining, at a access gateway, an array of guaranteed-bandwidth traffic-engineered (GBTE) tunnels;
deducing quality of service parameters for a communication flow associated with a mobile device;
applying, using a call admission control (CAC) mechanism, the quality of service parameters deduced for the communication flow against the array of GBTE tunnels to gain admittance into a particular GBTE tunnel in the array of GBTE tunnels; and
provisioning a sub-tunnel to transport the communication flow within the particular GBTE tunnel, wherein the particular GBTE tunnel has the capacity to carry the communication flow.

Abstract
An example method is provided and includes receiving a request from a mobile node for an Internet protocol (IP) address and establishing a point-to-point (PPP) link for the mobile node. The method also includes provisioning a first tunnel associated with a first communication flow for the mobile node, and provisioning a sub-tunnel with the first tunnel for a second communication flow. The second communication flow is associated with a high priority type of data to be transported on the sub-tunnel. In more specific embodiments, a call admission control (CAC) mechanism is used to establish the sub-tunnel with the first tunnel for the second communication flow. Additionally, an inner label is installed in a header of a packet associated with the second communication flow in order to identify the sub-tunnel.
