A dynamic service network creation apparatus includes a resource lookup and registration unit configured to look up and register network resource information of each of a plurality of network resource providers which are managed by a netstore apparatus; and a service network topology configuration unit configured to, in response to a service reservation request being received from each of a plurality of service providers through a service management system, dynamically configure a service network for providing a network-based service from the service provider to a service user that is to use the service of the service provider, wherein the dynamic service network creation apparatus is connected to the service management system that manages the network-based service provided by a plurality of the service providers and the netstore apparatus.

System and method for configuring dynamic service network based on netstore

Provided is a node control apparatus communicating an external Internet Protocol (IP) network and managing a plurality of mobile nodes included in a local network. The node control apparatus manages information relating to the plurality of mobile nodes, each equipped with one or more wireless interfaces, configures one or more groups by classifying the plurality of mobile nodes according to the type(s) of the wireless interface(s) of each of the plurality of mobile nodes, selects a representative node for each of the groups, and allows the member nodes of each of the groups to communicate with the external IP network via their representative node. Therefore, it is possible to minimize power consumption by selectively using a wireless interface for use in connecting to the representative node of each of the groups.

Energy-saving mobile node control method using wireless multi-interfaces

Provided are a method and apparatus for content delivery networking. There is provided a method of managing a content delivery network to transfer media content to a user, including: receiving a network configuration request and network configuration information, from a service provider that provides the content; receiving resource information including information about available resources required for configuring the network; and configuring a content delivery overlay network, based on the resource information and the network configuration information. Therefore, by configuring a content delivery overlay network for each provider, service and content providers having no unique content delivery method of their own can provide multimedia services based on applications for smart TV and web TV to a plurality of users.

Apparatus and method for configuring on-demand content delivering overlay network

An apparatus for distributing mobile resources in a cloud computing environment includes: a resource register configured to analyze, when a request for mobile resource registration is inputted by a user, the requested resource and confirm if the resource is registerable; a provisioning manager configured to create a MVO, when the mobile resource is a registerable resource, and register the mobile resource; a metadata repository configured to store metadata information regarding the registered mobile resource; and a resource manager configured to control the provisioning manager, when the resource register receives a request for the resource registration, so as to create a MVO, register the resource, and store metadata regarding the registered mobile resource information.

Apparatus and method for distributing cloud computing resources using mobile devices

A method includes transferring a general query message to managers of a mobility control server in response to receiving, from a router, the general query message for detecting a mobile node that requested to receive multicast data; storing, in a multicast mapping table, an address of the mobile node that requested to receive the multicast data when a membership report message of the mobile node is received from at least one of the managers and transferring the membership report message to the router; and forming a tunnel between the router and a manager that transfers the membership report message.

Mobile multicast system for supporting network-based mobility and method thereof

An apparatus and method for virtualizing multiple terminals are provided. The apparatus includes a terminal virtualizer configured to virtualize a group of a plurality of transmitter terminals of a first user and a group of receiver terminals of a second user through the change of source and destination addresses of a packet that is transmitted between the transmitter terminal group and the receiver terminal group so that the transmitter terminal group and the receiver terminal group may be recognized as if they were single terminals. Accordingly, it is possible to provide seamless IP connectivity regardless of which terminal is currently being used by a user.

Apparatus and method for virtualizing multiple terminals

An access point, a layer 2 switch, and multicast handover supporting method using the access point and the layer 2 switch are provided. According to the method of supporting multicast handover, when a mobile node is handed over from one cell to another while being provided with a multicast service in a wireless mobile communication network, the L2 switch performs multicast traffic routing in response to reception of MAC address information and multicast service source and group information from the access point. Hence, multicast traffic can be supported to be fast and seamlessly handed over within layer 2 network equipment.

Access point, L2 switch and method of supporting multicast handover using the access point and L2 switch

Provided are node authentication and node operation methods within service and access networks for bundle authentication between the service and access networks in a next generation network (NGN). A method of authentication processing of a node (S-CSC-FE/I-CSC-FE (Serving Call Session Control Functional Entity/Interrogating Call Session Control Functional Entity)) within a service network for bundle authentication between service and access networks, the method including: receiving first authentication information about access authentication of a terminal from a first node within the service networks; requesting to receive second authentication information from a second node within the service network based on the first authentication information; and comparing the first authentication information with the second authentication information to authenticate the terminal.

Node authentication and node operation methods within service and access networks in NGN environment

A method and apparatus for measuring the quality of a video provided in an IP network based media service is provided. The apparatus for measuring Quality of Experience (QoE) guaranteed real-time Internet Protocol (IP)-media video quality, includes: a receiver receiving a transmission video provided through an IP network service platform and an original video corresponding to the transmission video, and extracting frames of the transmission video and the original video; a detector comparing the frames of the transmission video and the original video in real time to obtain a difference between the frames of the transmission video and the original video and detecting a matching segment between the transmission video and the original video; and a measurement unit calculating a QoE parameter using the frames of the transmission video and the original video which correspond to the matching segment.
