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.

Abstract translation: 提供了一种示例性方法，包括从移动节点接收针对因特网协议（IP）地址的请求，并为移动节点建立点对点（PPP）链路。 该方法还包括配置与移动节点的第一通信流相关联的第一隧道，以及为第二通信流提供具有第一隧道的子隧道。 第二通信流与要在子隧道上传输的高优先级数据相关联。 在更具体的实施例中，使用呼叫许可控制（CAC）机制来建立具有用于第二通信流的第一隧道的子隧道。 另外，为了识别子隧道，内标签安装在与第二通信流相关联的分组的报头中。
