C- EFFICIENT POLICY ENFORCEMENT USING NETWORK TOKENS FOR SERVICES C-PLANE APPROACH

摘要

The device uses control plane signaling to establish flows associated with one or more applications. The gateway device obtains a request for a network token during control plane signaling. The gateway device derives the network token and transmits it to the device and / or access node during control plane signaling. A device and / or access node obtains a network token, wherein the network token is associated with a first one of the one or more flows, with a first one of the one or more applications, and provided to the device or access node via control plane signaling do. The network token may be included in the packet transmitted from the device to the user plane. The network token may be verified at the access node and / or gateway device using a cryptographic function and sent to its destination based on the results of the verification.
