In a system which manages path information and status of network with respect to a path being used for access to a storage apparatus and has a redundant path, when a fault occurs in the network, whether or not the path can be recovered by rerouting in network apparatuses is discriminated, thereby performing proper path switching. Construction information and the path information of the network are managed as information of the path which is being used for a storage access by a management server. Further, when the access path is made redundant, the management server obtains fault information in the network and information showing whether or not the path is being reconstructed from the network apparatuses, thereby discriminating the necessity of the path switching. If the path switching is necessary, the management server notifies a host computer and the storage apparatus of it and each apparatus executes a switching process.

Network security administrators are enabled with their customizable certificate authority reputation policy store which is informed by an independent certificate authority reputation server. The custom policy store overrides trusted root certificate stores accessible to an operating system web networking layer or to a third party browser. Importing revocation lists or updating browsers or operating system is made redundant. Proactive remediation is enabled to delete or disable root certificates in trusted operating system root certificate stores or in trusted browser root certificate stores by a web security agent installed at distributed endpoints. This removes the need for additional hardware or synchronous remote access over the protected endpoints.

The present invention provides a storage system capable of having a large-scale configuration for maintaining a write access response speed and reliability upon an occurrence of a failed cache and its control method. Plural clusters that control a disk drive connected thereto and have a cache memory are connected to one another through a cross coupling network, and write data in the cache memory of another cluster is mutually made redundant in the cache memories in two clusters that jointly use the same disk drive. When a failure occurs in the cache memory, the cluster that uses the disk drive jointly with the cluster having the cache memory in which the failure occurs performs processing for getting access to the disk drive performed by the cluster having the cache memory in which the failure occurs, and the other normally-operated cluster is caused to perform to only make redundant the write data in the cache memory in its cluster.

The system can make redundant rectifier modules dormant so as to save energy.

Network security administrators are enabled with their customizable certificate authority reputation policy store which is informed by an independent certificate authority reputation server. The custom policy store overrides trusted root certificate stores accessible to an operating system web networking layer or to a third party browser. Importing revocation lists or updating browsers or operating system is made redundant. The apparatus redirects or rewrites traffic to protect a plurality of endpoints from a man-in-the-middle attack when a certificate authority has lost control over certificates used in TLS.

When a communication path between a user site and a dual-homed data center is made redundant, a communication between the user site and a server within a data center can be continued. An edge node DCE-1 of a data center 40-1 and edge nodes TPE-1, TPE-2 of a transport network are connected to each other by a link TPE-1-1 and a link TPE-2-1, respectively. The edge nodes TPE-3 and TPE-1, TPE-2 that hold a node AE51 of a user site 50 are set with an LSP 110 of an active system, and an LSP 120 of a backup system, respectively. One of the links is active, and the other link is backup, and the LSP of the TPE node having the active link in the LSP 100 and the LSP 120 is made active. The respective links are prioritized, and the links are switched to an active state in order from the links higher in the order of priority when a link failure or an LSP failure occurs.

There is provided a line status monitoring circuit, a node, a communication system, and a failure occurrence determining method which can detect occurrence of a failure in some of redundant lines between nodes. A line status monitoring circuit receives a frame through one of a plurality of lines from another node connected through a redundant transmission channel which is made redundant by the plurality of lines. The line status monitoring circuit includes a line-specific check frame monitoring unit 51. If a line-specific check frame having an added dedicated header corresponding to each of the plurality of lines is received through one of the plurality of lines from another node, the line-specific check frame monitoring unit 51 determines whether or not a further line-specific check frame corresponding to a frame for checking which is identical to a frame for checking which the line-specific check frame corresponds to is received through a predetermined number or more of lines within a predetermined time. Then, if the further line-specific check frame is not received through the predetermined number or more of lines within the predetermined time, the line-specific check frame monitoring unit 51 discards the frame for checking corresponding to the first received line-specific check frame.

The invention discloses a method for producing tea pot with filtering holes in an inlet of a spout. The method is characterized in that the filter holes in a teapot body are wetted by means of a writing brush, then the whole teapot body is placed in glaze water, then the teapot coated with the glaze water is placed in water so as to make redundant glaze water on the filtering holes flow away, and finally the glazed teapot body is fired. The filtering holes are fully humidified before glazing, so that the filtering holes absorb enough moisture, and then the teapot is glazed; the filtering holes absorb enough moisture, so only little glaze water is left on the filtering holes, the glaze water on the filtering holes flows away after the teapot is placed in water, and accordingly the phenomenon that the filtering holes are blocked by the glaze water does not occur during glaze water firing.

The invention described herein is a system that features a Floormat and Handheld Sensor that operate in concert with a user's mobile device. The Floormat resembles a conventional bathroom scale, but features an enhanced set of measurements that include pulse rate and/or heart rate, SpO2, respiratory rate, weight, body composition, and Fluids. The Handheld Sensor features an integrated form factor that fits in a user's hand, which measures parameters such as blood pressure (e.g. systolic, diastolic, mean and pulse pressures), stroke volume, and cardiac output. Measurements of stroke volume and cardiac output require information from the Floormat (e.g., weight and body composition) to be sent to and processed by the Handheld Sensor. The Handheld Sensor can also make redundant measurements of heart rate, SpO2, and respiratory rate. Both systems transmit information through a wireless interface to a web-based system, where a clinician can analyze it to help diagnose a user.
