Abstract
An example method is provided and includes receiving a packet associated with a flow, determining a tunnel identifier for the flow, and determining a flow identifier for the flow. The method includes associating the flow identifier and the tunnel identifier to an Internet protocol (IP) address to generate a binding to be used for a network address and port translation (NAPT). In other embodiments, a routing decision is executed based on the binding between the identifiers and the IP address. The flow identifier can be a context identifier (CID), and the tunnel identifier can be a softwire tunnel ID. In yet other embodiments, the packet can be tagged as part of an encapsulation operation, which includes providing information about a network location at which the network address and port translation is to be executed.
