    • PURPOSE: A VPN(Virtual Private Network) service control device and a method thereof are provided to offer a reliable VPN service by controlling the devices comprising of an access network based on a carrier ethernet backbone network and an FTTH(Fiber To The Home) based access network. CONSTITUTION: A profile definition unit(100) defines a service profile which is necessary for setting a VPN between the end devices connected by a carrier ethernet backbone network. A VPN setting and managing unit(104) sets the VPN and connects the carrier ethernet backbone network to the access network based on the service profile defined by the profile definition unit. The VPN setting and managing unit intensively manages the access network and the carrier ethernet backbone network to provide the VPN service.

    • PURPOSE: A node device for content streaming relay and a method thereof are provided to supply a content streaming service to a user terminal in a multicast or a unicast transmission mode according to a check result of content features and network states. CONSTITUTION: A server connection unit(100) selects a streaming server(12) by considering load distribution according to a streaming request signal of a user terminal(14). When content transmitted to the user terminal is overlapped, a content caching and unicast transmitting unit(120) transmits the overlapped content to the user terminal in a unicast mode. When the content is converted, a multicast converting unit(130) transmits the content to the user terminal in a multicast mode.

    • PURPOSE: A channel allocation method in a WLAN(Wireless Local Area Network) system and method thereof are provided to maximize communication efficiency by directly designing a channel between access points. CONSTITUTION: An access point location identification module acquires the location information of an access point. A wireless channel design and calculation module determines the operation channel of the access point based on the location of the access point by acquiring the location of the access point using the location identification module. An access point wireless channel allocation and management module allocates the determined operation channel to the AP. A wireless channel verification module verifies the operation channel. An access point and channel database updates and stores the operation channel and operation channel information of the access points managed by a Wi-Fi zone management system.
