BINDING REGISTRATION METHOD, DATA FORWARDING METHOD, RELATED DEVICE, AND NETWORK SYSTEM |
摘要 |
A binding registration method, a data forwarding method, a related device, and a network system are disclosed. An SDN controller includes: a first receiving unit, configured to receive a first bearer message that is forwarded by a first MAG in multiple MAGs and that carries a first L2 attach request message; a first sending unit, configured to send, to each of the first MAG and an LMA, a message for establishing a tunnel between the first MAG and the LMA; a second sending unit, configured to send, to each of the first MAG and the LMA, a message for adjusting a flow entry of an MN; a configuration and encapsulation unit, configured to: configure an HNP(s) for the MN, and encapsulate the HNP(s) into an RA message; and a third sending unit, configured to send the RA message to the first MAG. |

1. A software defined networking (SDN) controller, wherein the SDN controller comprises: a processor for processing a message received from each network element, a receiver, and a transmitter, wherein:
the receiver, configured to receive a first bearer message that is forwarded by a first MAG in multiple mobile access gateways MAGs and that carries a first data link layer L2 attach request message, so that a mobile node MN requests to register with a network, wherein the first L2 attach request message is sent by the MN to the first MAG to request to access the first MAG, and the first L2 attach request message comprises an ID of the MN; the transmitter, configured to send, to each of the first MAG and a local mobility anchor (LMA), a message for establishing a tunnel between the first MAG and the LMA; the transmitter, configured to send, to each of the first MAG and the LMA, a message for adjusting a flow entry of the MN; the processor, configured to: when establishment of the tunnel between the first MAG and the LMA succeeds, configure a home network prefix HNP(s) for the MN, and encapsulate the HNP(s) into a router advertisement RA message; and the transmitter, configured to send the RA message to the first MAG, so that the MN is registered with the network when the MN receives the RA message from the first MAG. |
