摘要:
A reliable asymmetric method for distributing security information within a Fiber Channel Fabric. The Switching Fabric includes a set of security servers, which maintain among themselves a replicated copy of the Fabric security databases using the currently defined Merge and Change protocols. The other Switches of the Fabric are configured as client-Switches. They maintain only the subset of the authorization and authentication information required for their correct operation. A client-Switch queries the security server when a new end-device is connected to it, or when it is connected to the Fabric. When the security configuration of the Fabric changes by an administrative action, a security server solicits the client-Switches to update their information. In an alternative embodiment, the end-devices may query directly the security server, usually for authentication purposes. A Fabric with a plurality of security servers balances among them the load of inquiries from clients, and is more reliable because it continues to operate in the event of failure of one or more servers. Reliability is achieved in a stateless manner through the FSPF protocol, the Fiber Channel routing protocol. Each security server announces itself to the Fabric by advertising an adjacency to a predefined virtual Domain_ID in its FSPF LSRs. Clients access servers by directing queries to this virtual Domain_ID.

A facility for projecting future purchasing activity for a selected item being offered for sale by a merchant is described. The facility retrieves data indicating, during each plurality of past times, an observed level of browsing activity performed at the merchant with respect to the selected item. The facility transforms the retrieved data into a projection of future purchasing activity at the merchant for the selected item.

A divided clock signal is generated from an input clock signal. The duty cycle of the divided clock signal is programmed by generating a compare value based on values of duty cycle input and a divide value of the input clock signal. The compare value is compared to a count value to generate short and long pulse signals. The divided clock signal is generated based on the short and long pulse signals. The duty cycle of the divided clock signal varies in accordance with the compare value.

Usage of shared resources can be managed by enabling users to obtain different types of guarantees at different times for various types and/or levels of resource capacity. A user can select to have an amount or rate of capacity dedicated to that user. A user can also select reserved capacity for at least a portion of the requests, tasks, or program execution for that user, where the user has priority to that capacity but other users can utilize the excess capacity during other periods. Users can alternatively specify to use the excess capacity or other variable, non-guaranteed capacity. The capacity can be for any appropriate functional aspect of a resource, such as computational capacity, throughput, latency, bandwidth, and storage. Users can submit bids for various types and combinations of excess capacity, and winning bids can receive dedicated use of the excess capacity for at least a period of time.

A transmission node for use in a wireless communication network includes a first register for storing a set of first mask bits, a second register for storing a set of second mask bits, and a mask switching block for multiplexing the set of first mask bits and the set of second mask bits and outputting the set of third mask bits. The transmission node further includes a CPRI unit with an auxiliary interface for receiving the set of third mask bits. An activation block is connected between the CPRI unit and the mask switching block for causing the mask switching block to output the set of second mask bits based on data in a current frame in the CPRI unit.

摘要:
Segments of interest within video footage are identified automatically. Such segments of interest include portions of the footage which were taken using a hand held camera and which show a static subject, portions which track the motion of a moving subject, and portions which show an abrupt event. Methods are presented for identifying such segments, based on motion and/or color analysis of the video footage or based on observations of discontinuities in the video footage following a period of stability.
