Abstract:
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.
Abstract:
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.
Abstract:
A variable length packet data transmission apparatus and method are provided. The variable length packet data transmission apparatus using a variable length packet transmission technique includes a data transmitter generating synchronization information for synchronizing data communication with a data receiving apparatus, including the generated synchronization information in transmission data to be transmitted according to a variable length packet transmission technique, and transmitting the transmission data including the synchronization information to the data receiving apparatus, and a data receiver receiving the transmission data including synchronization information from a data transmission apparatus, reconstructing the synchronization information included in the received transmission data, and performing synchronization with the data transmission apparatus using the reconstructed synchronization information.
Abstract:
Provided is a satellite network communication system based on Second Generation Digital Video Broad-casting via Satellite (DVB-S2). A method for encapsulating transmission data in a digital satellite communication system includes: determining whether a time at which a reference time information packet has to be inserted into a packet data unit is arrived, in the digital satellite communication system; and if the time at which the reference time information packet has to be inserted into the packet data unit is arrived, transforming the packet data unit in the form of a baseband data packet including the reference time information packet. Therefore, by allowing transmission of Network Clock Reference (NCR) information in a satellite communication environment based on Generic Steam Encapsulation (GSE), bidirectional satellite communications are possible.
Abstract:
A method of reconstructing reference time information of a transmission frame in a digital satellite communication system is provided, including: receiving the transmission frame including reference time information; recording receiving time of start of frames of the plurality of physical layer frames included in the transmission frame; determining receiving time of a start of frame corresponding to the physical layer frames including the reference time information based on the recorded information when the physical layer frame including the reference time information is received; and reconstructing the reference time information based on the determined receiving time information of the start of frame. Network synchronization is stably acquired and maintained during two-way communication even in the satellite communication network environment.
Abstract:
Provided is a handover method for a mobile wireless network. The handover method for a mobile wireless network, including: receiving, by a mobile node, information on a new access router by requesting the information necessary for the handover from a previous access router in accordance with a handover initiation; sending a fast binding update message to the previous access router via the new access router by connecting to the new access router; receiving a packet from the new access router; and disconnecting from the previous access router.
Abstract:
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.
Abstract:
Provided is a service providing method and system by interoperation between service managers. Each of the service managers may manage an independent service area. Since the service managers interoperate with each other, a service target of an available service resource managed by a single service manager may be expanded to the entire service area. The entire service area may correspond to an area of summing up a service area managed by each of the service managers. Through the above expansion, a service may be efficiently delivered and provided to ensure a quality of service (QoS) requested by a user.
