Efficient policy enforcement using network tokens for service plan and approach

摘要

It is a device that establishes flows associated with one or more applications using control plane signaling. A communication port device obtains a request for a network token during control plan signaling. The gateway device derives the network token and sends it to the device and / or an access node during control plan signaling. the access device and / or node obtains the network token, where the network token is associated with a first stream of one or more streams, a first application among one or more applications, and provisioned to the device or node. access by means of control plan signaling. The network token can be included in a packet sent from the user plan from the device. The network token can be scanned at the access node and / or gateway using a cryptographic function and sent to its destination based on the scan results.
