PROTOCOL PROCESSING METHOD UNDER CONTROL AND FORWARDING DECOUPLING, CONTROL PLANE DEVICE, AND FORWARDING PLANE DEVICE

摘要

The present invention discloses a protocol processing method applied when control is decoupled from forwarding, a control plane device, and a forwarding plane device. The method includes: causing a control plane device to send an indication to a forwarding plane device according to a processing manner of a packet service processing protocol, and to deliver a negotiation parameter of the packet service processing protocol to the forwarding plane device; and causing the control plane device to receive a negotiation result of the packet service processing protocol, and to create a data path between a user equipment and a network device, where the negotiation result is uploaded by the forwarding plane device and obtained according to information that includes the negotiation parameter of the packet service processing protocol. In this way, when control is decoupled from forwarding on a gateway, the forwarding plane device can cooperate with the control plane device to perform packet service processing protocol negotiation.
