Abstract: Method and device for providing a multicast service are disclosed. A method for providing a multicast service according to the present invention includes: a step of configuring an error control policy which is applied to multicast data for a multicast service based on at least one of resource monitoring information of a transmitting terminal and service quality requirement information received from a plurality of receiving terminals; a step of transmitting multicast data to which the error control policy is applied to the plurality of receiving terminals; and a step of receiving feedback information for the muticast data from each of the plurality of receiving terminals and reconfiguring an error control policy based on at least one among the feedback information and resource monitoring information. [Reference numerals] (AA) Start;(BB) End;(S100) Receiving multicast service request information and service quality requirement information from a plurality of receiving terminals;(S110) Permitting multicast service providing for the plurality of receiving terminals;(S120) Configuring an error control policy applied to multicast data based on at least one among resource monitoring information and service quality requirement information of a transmitting terminal;(S130) Transmitting the multicast data to which the error control policy is applied to the plurality of receiving terminals;(S140) Receiving feedback information for the multicast data from each of the plurality of receiving terminals;(S150) Reconfiguring an error control policy based on at least one among the feedback information and resource monitoring information when at least one of the plurality of receiving terminals receives multicast data which does not satisfy the service quality requirement information as a result of analysis on the feedback information

Abstract: PURPOSE: An apparatus and method for performing discovery based on a priority in a distributed network and method for determining discovery backoff time are provided to efficiently discover an appropriate network node according to situation by reflecting significance or a priority of a discovery object. CONSTITUTION: A network node # 1(100) comprises a data processing unit(110), a discovery performing unit(120), and a communication unit(130) The data processing unit processes applications related to the operation of the network node #1. The data processing unit provides a data distribution service. The discovery performing unit performs a participant discovery process and an end point discovery process. The discovery performing unit generates a discovery message. The discovery performing unit determines discovery backoff time based on a priority. The discovery performing unit obtains a priority level of a network node by requesting the priority level for an application layer performed in data processing unit.

Abstract: PURPOSE: A method and an apparatus for providing lightweight multicast in a data distributing service are provided to restore the congestion of networks based on minimized controlling commands. CONSTITUTION: A network congesting detecting part(111) multicasts packets based on reader node terminals and detects the congestion causes of networks based on negative responding messages transmitted from reader node terminals without the reception of the packets. A network restoring controlling part(112) determines restoring policies according to the congestion causes of the networks and overcomes the congestion causes. The negative responding message includes a first reader congestion cause generated based on the cross-layered congestion tracking table of the reader node terminals without the reception of the packets.

Abstract: PURPOSE: A method and a system for discovering a communication entity using a discovery gateway are provided to ensure stability and reliability not only in a search procedure but also in performing whole applications by performing a distributed search procedure through requests and responses between communications entities. CONSTITUTION: A first local network(102) and a second local network are connected through a via network(105). A search gateway is installed inside a first local domain(310) and a second local domain(320). A first search gateway(103) in the first local domain is connected to a second search gateway(107) in the second local domain. The search gateway is formed in the same device or a separate device of network devices(104,106) to connect a local network to the via network.
