Abstract
Embodiments of this application provide a communication method and a related device. In the method, a control plane (CP) sends a first message to a user plane steering function (USF). The first message includes end user information, and indicates the USF to schedule an end user based on the end user information. Then, the CP determines, based on an identifier of a target UP carried in a first request message sent by the USF, to schedule the end user to the target UP. Thus, a scheduling policy of the end user is determined via the USF. The CP further processes a connection between the end user and the target UP based on the identifier of the target UP.
Claims19
A network device, applied to a control plane (CP), in a broadband network gateway (BNG) system having a user plane steering function (USF) and a software-defined network (SDN) controller, comprising:
- at least one processor;
- one or more memories coupled to the at least one processor and storing programming instructions, wherein the at least one processor is configured to execute the programming instructions to cause the CP in the BNG system to:
- send a first message to the USF in the BNG system, wherein the first message comprises end user information, and the end user information comprises user access information and service level agreement (SLA) information;
- receive a first request message from the USF in the BNG system, wherein the first request message comprises an identifier of a target user plane (UP) from multiple UPs managed by the CP, and the target UP is associated with an end user;
- and
- process a connection between the end user and the target UP based on the identifier of the target UP,
- wherein a virtual local area network (VLAN) identifier of the end user and an identifier of a target steering function (SF) associated with the end user are determined based on the first message, and a second request message that includes the VLAN identifier, the identifier of the target SF, and the identifier of the target UP is sent to the SDN controller in the BNG system.

- determine a target user plane (UP) associated with an end user based on the first message, wherein the target UP is determined from multiple UPs managed by the CP in the BNG system;
- send a first request message to the CP, wherein the first request message comprises an identifier of the target UP:
- determine an identifier of a target steering function (SF) associated with the end user and a virtual local area network (VLAN) identifier of the end user based on the first message;
- and
- send a second request message to the SDN controller in the BNG system, wherein the second request message includes the VLAN identifier, the identifier of the target SF, and the identifier of the target UP.
A broadband network gateway (BNG) system, comprising:
- a control plane (CP) configured to manage multiple user planes (UPs);
- a user plane steering function (USF);
- and
- a software-defined network (SDN) controller,
- wherein the CP is configured to:
- send a first message to the USF, wherein the first message comprises end user information, and the end user information comprises user access information and service level agreement (SLA) information;
- receive a first request message from the USF, wherein the first request message comprises an identifier of a target user plane (UP), and the target UP is associated with an end user, and the target UP is determined from multiple UPs managed by the CP;
- and
- process a connection between the end user and the target UP based on the identifier of the target UP, and
- wherein the USF is configured to:
- receive the first message from the CP;
- determine the target UP associated with an end user based on the first message, wherein the target UP is determined from multiple UPs managed by the CP;
- send the first request message to the CP;
- determine an identifier of a target steering function (SF) associated with the end user and a virtual local area network (VLAN) identifier of the end user based on the first message;
- and
- send a second request message to the SDN controller, wherein the second request message comprises the VLAN identifier, the identifier of the target SF, and the identifier of the target UP.
