Abstract
A method for managing a mobile node of an SDN controller according to an aspect of the present disclosure includes receiving a router solicitation message of a mobile node transmitted through a first AP operated by the SDN controller.
Claims11
A method for managing a mobile node of a software-defined networking (SDN) controller, comprising:
- receiving a router solicitation message of a mobile node transmitted through a first AP operated by the SDN controller;
- allocating a prefix to each flow based on information relating to a flow type included in the router solicitation message by the mobile node;
- storing the allocated prefix information in a binding cache entry (BCE) for each of the mobile node;
- transmitting a router advertisement message confirming that the information relating to the flow type is registered in the SDN controller to the mobile node through the first AP;
- and
- transmitting a flow transmitted in the mobile node to a destination node in accordance with the prefix information stored in the BCE,
- wherein, in the router solicitation message, information for distinguishing between a first type that does not require session maintenance of a flow recorded by the mobile node, a second type that requires the session maintenance of the flow, or a third type in which an IP of the flow is fixed is recorded, and
- the allocating the prefix allocates a first prefix to the first type and the third type of the flows, and allocates a second prefix to the second type of the flow.

A device for managing a mobile node of a software-defined networking (SDN) controller, comprising:
- a memory in which a program for performing a method for managing the mobile node of the SDN controller is stored and
- a processor for executing the program stored in the memory,
- wherein the processor is configured to:
- allocate a prefix to each flow based on information relating to a flow type included in a router solicitation message of a mobile node transmitted through a first AP operated by the SDN controller by the executing of the program,
- store the allocated prefix information in a binding cache entry (BCE) for each of the mobile node,
- transmit a router advertisement message informing that the information relating to the flow type is registered to the mobile node through the first AP,
- transmit a flow transmitted in the mobile node to a destination node in accordance with the prefix information stored in the BCE,
- wherein, in the router solicitation message, information for distinguishing between a first type that does not require session maintenance of a flow recorded by the mobile node, a second type that requires the session maintenance of the flow, or a third type in which an IP of the flow is fixed is recorded, and
- wherein the processor is configured to allocate a first prefix to the first type and the third type of the flows, and allocate a second prefix to the second type of the flow.
