Abstract
A BRAS system-based packet encapsulation method includes obtaining user access information when receiving a user access protocol packet and performing VXLAN GPE encapsulation on the user access protocol packet based on the user access information. The encapsulation structure includes a user information header that is used to store the user access information, and a quantity of bytes occupied by the user information header is less than or equal to 12. In this application, the foregoing encapsulation structure is used to encapsulate a packet.
Claims17
A method implemented by a user plane device, the method comprising:
- obtaining user access port information corresponding to a user access protocol packet;
- and
- transmitting, to a control plane device, the user access protocol packet and the user access port information,
- wherein the user plane device implements a broadband remote access server user plane (BRAS-UP), and
- wherein the control plane device implements a broadband remote access server control plane (BRAS-CP).
An apparatus, comprising:
- a memory configured to store instructions;
- and
- a processor coupled to the memory and configured to execute the instructions to:
- receive a user access protocol packet;
- transmit, to a first device, the user access protocol packet and user access port information corresponding to the user access protocol packet, wherein the apparatus implements a broadband remote access server user plane (BRAS-UP);
- and
- transmit, to a second device, a protocol type of the user access protocol packet or a packet type of the user access protocol packet, wherein the second device implements a broadband remote access server control plane (BRAS-CP).
A system, comprising:
- a network device configured to:
- obtain user access port information corresponding to a user access protocol packet;
- and
- transmit the user access protocol packet and the user access port information;
- and
- a controller coupled to the network device and configured to:
- receive, from the network device, the user access protocol packet and the user access port information;
- and
- control, based on the user access protocol packet and the user access port information, the network device,
- wherein the network device implements a broadband remote access server user plane (BRAS-UP), and
- wherein the controller implements a broadband remote access server control plane (BRAS-CP).
A computer program product comprising computer-executable instructions stored on a non-transitory computer-readable storage medium that, when executed by a computer, cause the computer to:
- obtain user access port information corresponding to a user access protocol packet;
- and
- transmit, to a device, the user access protocol packet and the user access port information,
- wherein the computer comprises implements a broadband remote access server user plane (BRAS-UP), and
- wherein the device implements a broadband remote access server control plane (BRAS-CP).
