Abstract: An importance degree prediction apparatus includes a path change determination unit that generates alarm path change information including path change information when a path is changed and an alarm developing when the path is changed in a network. The apparatus includes a reception unit that searches alarm path change information of a new alarm when the alarm is received from a development prediction apparatus, and a prediction unit that predicts a traffic amount in a post-change path based on a traffic amount in a pre-change path in the searched alarm path change information. The apparatus includes a calculation unit that calculates a criticality degree in the network based on a ratio of the predicted traffic amount in the post-change path that exceeds a predetermined allowable amount, and a determination unit that determines an alarm importance degree of the received alarm corresponding to an influence degree based on the criticality degree.

Abstract: A communication monitor includes a path change determining unit that generates path change information including a path change at the time of the path change in a network and an alarm at the time of the path change, and a collecting unit that collects traffic information of each path in the network. The communication monitor further includes an evaluating unit that calculates a degree of coincidence of traffic information representing a degree by which traffic information at the time of the current path change coincides with previous traffic information in the path change information immediately before the path change. The communication monitor further includes a predicting unit that predicts an alarm of the path change information related to the previous traffic information as an alarm at the time of the current path change when the degree of coincidence of the traffic information exceeds an alarm threshold value.

Abstract: A file storage control device (for example NAS) comprises a storage space provision portion, which provides, to a higher-level device used by a user, a single storage space associated with a plurality of logical storage units (LUs) provided by a storage system; a reception portion, which receives requests to write files to the provided storage space from the higher-level device; and a storage control portion, which selects a LU from among the plurality of LUs associated with the storage space specified by the write request, and stores all the data constituting the file according to the write request in the selected LU.

Abstract: A VPN gateway (A11) includes a WAN interface (A111) for exchanging packets with client nodes (C1, C2, D1, D2) via IPsec tunnels (B11-B14) set on the WAN side, a LAN interface (A112) for exchanging packets with server nodes (A131-A136) connected to the LAN side, a session relay unit (A114) for temporarily terminating a first communication session to be set for a sever node from a client node, and setting a second communication session that relays the first communication session to the server node, and an SSL processor (A116) for making the second communication session into an SSL. This arrangement makes it possible to dynamically allocate the servers in a data center (A1) to a VPN, permit only an authenticated server to communicate with another node in the VPN, and prevent wiretapping and tampering of communication performed by the server.

Abstract: Provided is a method for controlling a computer system including a first server computer, a second server computer, at least one data storing device, and a client computer. The first server computer manages a first file system. The second server computer manages a second file system. The second file system includes data copied from the first file system. Data written in the second file system after data is copied from the first file system is stored in a shared volume. In the method, when a load on the second server computer is higher than a load on the first server computer, copy of the data stored in the shared volume to the first file system is started and a read request from a client computer is issued to the first server computer. Accordingly, it is possible to execute high-speed distribution of an access load of a storage system.

Abstract: The invention provides a method for manufacturing a soft magnetic powder material covered by oxide layers at surfaces of the powder, by using a soft magnetic alloy powder containing a soft magnetic powder material and a second element such as Si having an oxidizing reactivity higher than iron, and heating the soft magnetic alloy powder in an atmosphere of a weak oxidizing gas by mixing a weak oxidizing gas in an inert gas, and oxidizing selectively the second element at surface layers of the powder while restraining an oxidation of iron to form thin oxide layers with high electrical resistance.

Abstract: An SIP (Session Initiation Protocol) server sharing module relays SIP messages which are transmitted and received between a plurality of client groups and a SIP proxy server shared by the plurality of client groups. The SIP server sharing module includes a message source group identifying section configured to identify a specific client group to which a specific client terminal belongs which transmits a client transmission SIP message, from the client transmission SIP message which is transmitted to the SIP proxy server from each of client terminals belonging to the plurality of client groups, and a group tag insetting section configured to insert a group tag corresponding to the specific client group identified by the message source group identifying section in the client transmission SIP message. A group tag removing section removes a group tag contained in a server transmission SIP message transmitted to a destination client terminal, which belongs to the specific client group, from the SIP proxy server.

The capacity calculating step includes a sub-step of calculating a capacity deterioration index S, as a ratio of capacity decrease caused by battery deterioration. The discharging capacity, calculated from the discharging capacity, operating as a reference, using the corrected voltage V, is further multiplied with the capacity deterioration index S to calculate the discharging capacity.
