Abstract: A method and system for providing flow mobility in a distributed mobility management network are disclosed. The method of controlling data flow mobility can include: (a) receiving session information in correspondence to a connection to each mobile access router from said mobile access router and storing the session information, which may include terminal information, an allotted address, and data flow information; (b) determining a target data flow to be moved by analyzing the session information according to a flow movement policy; and (c) transmitting a flow movement request, which includes the allotted address corresponding to the determined target data flow, to a new mobile access router.

Abstract: A method and a system for supporting mobility of a mobile terminal in a distributed mobile network based on a SDN are disclosed. A method of supporting a fast handover of a mobile terminal in a node-B (eNB) includes the steps of: receiving a handover initiation message from the mobile terminal, the handover initiation message including identification information and signal strength of a target eNB; determining whether or not for a fast handover trigger using the signal strength of the target eNB and movement history of the mobile terminal previously stored; and when it is determined as the fast handover trigger, transmitting a handover request message and a rule for the handover to the target eNB by using the identification information of the target eNB.

Abstract: Provided is a method for managing an address for an application of a LISP (Locator ID Separation Protocol) network system in a distributed container-based virtualization environment, and the method comprises detecting, by a service discovery agent of a container platform, generation of an application in a corresponding cluster; querying, by the service discovery agent, a service IP address to be assigned to an application to be generated by transmitting a service name to a central control plane; searching, by the control plane, for a service IP address matching the service name and transmitting the service IP address to the service discovery agent; and transmitting, by the service discovery agent, the service IP address to a manager of the container platform to complete the generation of the application, and mapping the service IP address to a public IP for the generated application to register it in the control plane.
