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.
Claims20
A method implemented by a network device, comprising:
- obtaining user access information corresponding to a user access protocol packet, wherein the user access information comprises user access port information;
- and
- encapsulating the user access protocol packet with an encapsulation header to produce an encapsulated packet, wherein the encapsulated packet comprises the user access protocol packet and the encapsulation header, and wherein the encapsulation header comprises the user access information with the user access port information.
An apparatus, comprising:
- a receiver configured to receive a user access protocol packet;
- and
- a processor coupled to the receiver and configured to execute instructions to cause the apparatus to:
- obtain user access information corresponding to the user access protocol packet, wherein the user access information comprises user access port information;
- and
- encapsulate the user access protocol packet with an encapsulation header to produce an encapsulated packet, wherein the encapsulated packet comprises the user access protocol packet and the encapsulation header, and wherein the encapsulation header comprises the user access information with the user access port information.
A system, comprising:
- a network device configured to:
- obtain user access information corresponding to a user access protocol packet, wherein the user access protocol packet comprises user access port information;
- and
- encapsulate the user access protocol packet with an encapsulation header to produce an encapsulated packet, wherein the encapsulated packet comprises the user access protocol packet and the encapsulation header, and wherein the encapsulation header comprises the user access information with the user access port information;
- and
- a controller coupled to the network device and configured to control the network device.
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 information corresponding to a user access protocol packet, wherein the user access information comprises user access port information;
- and
- encapsulate the user access protocol packet with an encapsulation header to produce an encapsulated packet, wherein the encapsulated packet comprises the user access protocol packet and the encapsulation header, and wherein the encapsulation header comprises the user access information with the user access port information.
