Abstract:
PURPOSE: A load balancing apparatus and a load balancing method thereof are provided to distribute a load balancing function to multiple components for preventing the load balancing apparatus from being overloaded. CONSTITUTION: A balancing unit (120) determines at least one server among multiple physical servers included in a server farm as a target server to provide a client a service. The balancing unit determines a forwarding path between the target server and the client and a forwarding rule in respect of the forwarding path. A network unit (110) is positioned on the forwarding path. The network unit comprises at least one or more switches. At least one or more switches forwards a data packet received from the client to the target server on reference to the forwarding rule.
Abstract:
PURPOSE: In case a mobile terminal has the interface of different service providers, a mobility system based on a network and a handover method thereof are provided to realize the inter-domain flow binding of different service providers without the intervention of the mobile terminal. CONSTITUTION: A first domain(200) receives the new access fact of a mobile terminal(100) from a second domain(300). The first domain decides the binding change of the flows of the mobile terminal bound to the first domain. In case a flow in which the binding change is necessary exists, the first domain transfers a binding setting request for a corresponding flow to the second domain. In case the binding of the flow is completed, the first domain establishes a tunnel with the second domain.
