There is provided a method for managing an Ethernet ring network of a VLAN-based bridge that includes: registering a major-ring VID (VLAN ID) in a ring port filtering database of a ring protection link owner node in accordance with a request for registering the major ring VID (VLAN ID) from an ERP (Ethernet Ring Protection) controller mounted on the ring protection link owner node of a major ring; delivering, by the ring protection link owner node, a VID registration message to other nodes which belong to the major ring through a ring port; receiving the VID registration message through the ring port and registering the major ring VID in a ring port filtering database of each node itself, by each node which belongs to the major ring; and delivering, by each node which belongs to the major ring, the VID registration message to other nodes which belong to the major ring through the ring port.

There is provided a packet transport layer apparatus. The packet transport layer apparatus can receive frames having different formats via a single port by dividing a single physical port into a plurality of virtual ports according to each frame format, can increase the number of customer virtual local area networks (C-VLANs) and the number of service VLANs (S-VLANs) being usable at the same time by assigning a different component identifier (ID) to each frame format and using the component ID as a factor used in searching a filtering table, and can translate a frame format to be suited to a frame format allocated to a virtual output port.

A metadata server in an asymmetric cluster file system detects the used capacity and the free capacity of a disk volume in a data server to allocate chucks. The method for selecting a disk volume includes receiving status information from a data server periodically and adjusting the standby command number of a disk volume in the disk server on the basis of the status information, and selecting a disk volume for chunk allocation on the basis of the standby command number in response to a chunk allocation request from a client.

The present invention provides a light emitting device, comprising a first light emitting diode for emitting light in an ultraviolet wavelength region; at least one phosphor arranged around the first light emitting diode and excited by the light emitted from the first light emitting diode to emit light having a peak wavelength longer than the wavelength of the light emitted from the first light emitting diode; and at least one second light emitting diode for emitting light having a wavelength different from the peak wavelength of the light emitted from the phosphor.

A method for mitigating interference at a small base station in a hierarchical cell structure is provided. In the method, the small base station checks a sub-frame allocated to macro user equipment by using a downlink signal received from a macro base station when an interference candidate user equipment list is received. The interference candidate user equipment list contains information on the macro user equipment adjacent to a femto cell controlled by the small base station. Then the small base station allocates other sub-frame to femto user equipment located in the femto cell by avoiding the sub-frame allocated to the macro user equipment.

A cooperative relay method and system in a multi-hop relay network are provided. The method may include receiving, at a first time slot, resource allocation information from a base station, and identifying a first hop Mobile Station (MS) data zone, receiving, at the first time slot, first hop MS data in the identified first hop MS data zone, and storing the received first hop MS data, and receiving, at a second time slot, second hop MS data from a relay station, and combining the first hop MS data with the second hop MS data. The resource allocation information may be an MS MAP indicating a first hop MS data zone, a simultaneous assignment MS MAP indicating both a first hop MS data zone and a second hop MS data zone, or a relay MAP indicating a first hop MS data zone.
摘要:
An object-based storage system for deferring elimination of a shared file includes a user file manager and a metadata management server, such that even if an inode shared by a plurality of user file managers connected over a network is eliminated by one of the user file managers, the elimination of the inode is deferred until the use of the inode of another user is completed. When a file elimination request of the user is received, the user file manager sends a request message for transferring an elimination inode corresponding to the file to a temporary directory. The metadata management server receives the request message, and sends a message for transferring an object of the elimination inode to the temporary directory to at least one user file manager connected with the user file manager over the network. Accordingly, every user file manager can use the object-based storage system without considering error processing for an eliminated inode.

Provided is a method of manufacturing a circuit which includes: (a) providing a substrate made of a conductive material; (b) etching a first surface of the substrate excluding a region in which at least one via is to be formed; (c) etching a region of the etched first surface of the substrate in which an insulated portion of a first circuit is to be formed; (d) stacking a first insulation layer in spaces formed by the etching performed in operations (b) and (c); and (e) grinding a second surface of the substrate to expose the first insulation layer outward along with the first circuit, thereby forming a circuit board.
