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.

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.

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.

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.

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.

Disclosed is a method of calculating parity. The method dividing, by a client system, a file which is to be stored into chunks of a preset size and distributively storing the chunks in a plurality of data servers; sending, by the client system, a data write complete notification message to a metadata server; storing, by the metadata server, a file sent through the data write complete notification message in a recovery queue; and sending, by the metadata server, a random data server a parity calculation request for the file stored in the recovery queue.
