Abstract:
Disclosed is an apparatus for managing a traffic load in a content sharing environment where a sending node sends a search message to a receiving node and the receiving node which has received the search message sends a response message to the sending node in a delay tolerant network. In an anti-packet generating part, the receiving node and a first delivery node which has firstly delivered the search message to the receiving node generate and store a first anti-packet for preventing diffusion of the search message, and the sending node and a second delivery node which has firstly delivered the response message to the sending node generate and store a second anti-packet for preventing diffusion of the response message. In an anti-packet delivery part, the receiving node and the first delivery node, if they meet other third delivery node, deliver a first anti-packet and the sending node and the second delivery node, if they meet other fourth delivery node, deliver a second anti-packet. A control part removes a message owned by a fifth delivery node by using the response message without copying the second anti-packet if the fifth delivery node which has received a copied response message to be transmitted from the receiving node to the sending node, is a delivery node having the same with the search message. The present invention applies the IMMUNE_TX and the VACCINE scheme, frequently used for preventing unnecessary message diffusion in delivering a one way message from the sending node to the receiving node, to a content sharing environment and operate the search message and the response message with the anti-packet, thereby reducing the message diffusion.
Abstract:
Disclosed are an apparatus and a method for selecting one shortest path from multi-paths based on bridge ID which is modified into various forms in an Ethernet backbone network and an Ethernet subscriber backbone network. A bit masking unit divides the bridge ID into 4-bit units and converts an arbitrary bit 1 into 0 and 0 into 1. A bit rotation unit rotates the position of an arbitrary bit. A path selecting unit selects the shortest path based on a predetermined priority rule. According to the present invention, it is possible to select a path in a more equitable way, by changing some parts of a bridge priority masking method being used in the current standard method (IEEE 802.1ad). Thus, the rate of use of a transmission link is increased and the performance of the network is improved.

Provided is a server for providing an RTCWeb service for an IMS network The disclosed server is an RTCWeb server for providing an RTCWeb service for an IMS network; and comprises an RTCWeb module which communicates with one or more RTCWeb clients and which carries out operations related to the RTCWeb service; an IMS module which communicates with an S-CSCF of an IMS and which carries out operations as an IMS client; and a message translation module for translating an IMS relating message and an RTCWeb relating message.
Abstract:
A media controller, a p2p-based streaming contents sharing method thereof, and a home network system related to the same are provided. A provided home network system in a home network system includes: a first media renderer for receiving a peer list from a tracker of an external p2p network system, receiving at least streaming contents from at least one peer comprising the p2p network system and playing the contents; and a media controller for receiving information related to the streaming contents from the first media renderer and registering the streaming contents wherein the media controller transmits a streaming transmission request message to the first media renderer to play the streaming contents in the second media renderer when a contents providing request from the second media renderer in the home network system is received. According to the present invention, the network traffic which is concentrated on a p2p-based streaming contents provider can be reduced. Furthermore, according to the present invention, the p2p-based streaming contents can be efficiently shared.

PURPOSE: A node device, a message transmission method, and a program recording medium thereof are provided to increase a message diffusion range by distributing many messages to a node which is rapidly moved. CONSTITUTION: A mobile information measuring unit(120) measures first mobile information based on location information. The first mobile information includes the moving speed of the mobile information measurement unit and mobile ranges. A mobile information comparison unit(130) compares the first mobile information with second mobile information received from other nodes. The second mobile information includes the mobile speed and mobile range of the other nodes. A message transmission unit(140) transmits a message by setting the amount of the message transmitted to the other nodes by comparing the first mobile information and the second mobile information.

Abstract:
PURPOSE: A node included in a wireless network and address creation method thereof are provided to offer a subscribing/publishing service in nodes by effectively routing P2MP(Point-to-MultiPoint) traffic. CONSTITUTION: A reception unit(310) receives events or diverse information used for transmitting and receiving data and controlling nodes. A transmission unit(320) transmits the event and the diverse information to other nodes. A control unit(330) creates a message for establishing a data transmission path which is arranged to a lower node direction or an upper node direction, an address for transmitting and receiving the data, and selects a parent node/childe node.
