The present invention relates to an apparatus and method of performing an error recovery process in an asymmetric clustering file system that has higher efficiency in data recovery when a data server in an asymmetric clustering file system fails than a method of processing the data recovery in the metadata server. The present invention includes receiving a chunk list requiring recovery by a data server included in the other data server groups than a data server group including a failed data server among a plurality of data server groups, requesting chunk data necessary for recovering an erroneous chunk from a data server in the other data server groups to the other data servers than the failed data server in the data server group, and recovering the erroneous chunk based on the chunk data by the data server in the other data server group.

An apparatus and method for resource allocation information transmission is provided. The method includes determining a search space for use in a second frequency band using resource allocation information of a first process detected in a first frequency band, detecting resource allocation information using the search space in the second frequency band, and when failing to decode received data according to the resource allocation information detected in the second frequency band, re-detecting resource allocation information of the first process in the second frequency band in a first time interval using the search space without detecting the resource allocation information of the first process in the first frequency band.

A method for protection switching of a ring network, which includes a plurality of nodes disposed in a ring shape, includes: allowing a node adjacent to a failure link among the plurality of nodes to generate a failure protection switching frame when the failure link is generated in the ring network; allowing the node adjacent to the failure link to transmit the failure protection switching frame to an adjacent node; allowing each of the plurality of nodes to delete address lists connected with the ring network except for an external network (hereinafter referred to as subnet) from their own forwarding table; allowing each of the plurality of nodes to transmit a subnet address list protection switching frame including a subnet address list; and allowing a node receiving the subnet address list protection switching frame to update the forwarding table on the basis of the subnet address list included in the frame.
摘要:
An apparatus and method for operating a Codebook Subset Pattern (CSP) of a Base Station (BS) in a Multiple Input Multiple Output (MIMO) system are provided. The method includes determining whether there is a CSP-updated BS among the BS and adjacent BSs, exchanging the updated CSP between cells if it is determined that there is a CSP-updated BS, and broadcasting the CSP of each cell acquired through the exchange thereby reducing an inter-cell interference in the MIMO system
摘要:
A method and apparatus for protection switching in a ring network are provided. A method for protection switching in a ring network, which includes a first ring network having first and second connection nodes and a second ring network connected with the first ring network through the first and second connection nodes, includes: receiving, by the first connection node, first and second R-APS messages transmitted from nodes belonging to the first ring network; determining, by the first connection node, the position of closure in the first ring network by using the first and second R-APS messages and topology information; receiving, by the first connection node, a topology change signal transmitted from the second ring network; and transmitting, by the first connection node, an FDB flush message with reference to the position of closure.
摘要:
An apparatus and method for communication of a Mobile Station (MS) of a shadow area in a mobile communication system are provided. The method includes determining whether an Emergency Ad-hoc Relay (EAR) amble is received and transmitting a help signal when the EAR amble is not received.
摘要:
Provided are a file storage system, and a method for managing duplicate files in the file storage system. The file storage system that performs file duplication for error recovery includes a client for requesting generation of a duplicate file of a new file being stored, a metadata server for storing information associated with prestored duplicate files and determining whether a file that is identical to the new file is present among the prestored duplicate files, to limit a number of identical duplicate files to a preset number, and a data server comprising a file duplication unit and a storage unit for respectively performing file duplication and file storage under the control of the metadata server. Accordingly, file recovery can be performed while duplicate files in the system are minimized.
摘要:
A method and system for performing P2P communications in a communication system are provided, in which a first MS transmits a request signal requesting P2P communications with a second MS and a unique identification number of the second MS to a BS, receives from the BS a CID of the second MS allocated by the BS and transmission information required for initial synchronization of the P2P communications in response to the request signal, acquires synchronization with the second MS using the CID of the second MS and the transmission information, and establishes a P2P connection with the second MS.
