Abstract
In a message transmission method, an access controller receives a first message from an access node, and the first message includes a first identifier. The access controller obtains a line identifier according to the first identifier. The access controller obtains a second message according to the line identifier, and the second message includes the line identifier. The access controller sends the second message to a relay server.
Claims24
A method comprising:
- receiving, from an access node, a first message comprising a first identifier, wherein the first identifier comprises a tunnel identifier, a medium access control (MAC) address of the access node, or an Internet Protocol (IP) address of the access node;
- obtaining, based on the first identifier, a second message comprising a line identifier corresponding to the first identifier;
- sending, to a relay server, the second message;
- receiving, from the relay server, a fourth message comprising the line identifier and an IP address prefix;
- obtaining, based on the line identifier, a third message comprising the IP address prefix and the first identifier;
- and
- sending, to the access node, the third message.

An access controller comprising:
- a non-transitory computer-readable storage medium configured to store programming instructions;
- and
- a processor coupled to the non-transitory computer-readable storage medium and configured to execute the programming instructions to cause the access controller to:
- receive, from an access node, a first message comprising a first identifier, wherein the first identifier comprises a tunnel identifier, a medium access control (MAC) address of the access node, or an Internet Protocol (IP) address of the access node;
- obtain, based on the first identifier, a second message comprising a line identifier corresponding to the first identifier;
- send, to a relay server, the second message;
- receive, from the relay server, a fourth message comprising the line identifier and an IP address prefix;
- obtain, based on the line identifier, a third message comprising the IP address prefix and the first identifier;
- and
- send, to the access node, the third message.
7 more elements
An access apparatus comprising:
- a non-transitory computer-readable storage medium configured to store programming instructions;
- and
- a processor coupled to the non-transitory computer-readable storage medium and configured to execute the programming instructions to cause the access apparatus to:
- receive, from a user, a second message comprising a Dynamic Host Configuration Protocol (DHCP) message or a router solicitation (RS) message;
- obtain a first message based on the second message, wherein the first message comprises the second message and a first identifier corresponding to a line identifier, whereinand wherein the first identifier comprises a tunnel identifier, a medium access control (MAC) address of an access node, or an Internet Protocol (IP) address of the access node;
- send, to an access controller, the first message;
- receive, from the access controller, a third message comprising the first identifier and a fourth message, wherein the fourth message comprises an IP address prefix;
- and
- send, to the user based on the line identifier, the fourth message.
