  • Patent number: 7675543
    Abstract: 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.

  • Patent number: 7649844
    Abstract: Methods and apparatus are provided for improving fiber channel packet delivery. Techniques are provided for the in-order delivery of packets by blocking incoming packets associated with a port channel change at a fiber channel switch and sending flush messages onto links associated with a port channel change. Upon receiving acknowledgments for the flush messages, incoming packets are unblocked.

  • Patent number: 7593324
    Abstract: A port shutdown protocol coordinates among various components involved in the process of administratively bringing down a link at both ends of a link connecting two switches. Execution of the protocol avoids or reduces frame drops and/or reordering. In this protocol, peer switches perform various actions when bringing down an ISL in a synchronized manner. In one implementation, this protocol uses the Exchange Peer Protocol (EPP) as the underlying transport to carry the port shutdown protocol frames.

  • Patent number: 7549017
    Abstract: Methods and apparatus are provided for efficiently selecting virtualization engines in storage area networks. Initiators, targets, and candidate virtualization engines associated with a virtual logical unit number (VLUN) are identified and characteristics such as latency, network topology, load, and mirroring and striping characteristics are analyzed and used to efficiently select a virtualization engine for a particular VLUN in a storage area network. A virtualization engine can be implemented in a line card associated with a fibre channel switch.

  • Publication number: 20080153546
    Abstract: An embodiment of a method for subscriber identity module (SIM) application toolkit (SAT) management, performed by a processing unit of a mobile station, is provided. A SAT shortcut to a SAT final node, or to a sub-menu including the SAT final node, is created. A value-added service (VAS) provided by a SAT application of a remote server is requested when selecting the SAT shortcut to the SAT final node. The sub-menu is displayed when selecting the SAT shortcut to the sub-menu.

  • Patent number: 7327744
    Abstract: According to the present invention, methods and apparatus are provided to improve the techniques and mechanisms for forwarding packets at a fiber channel switch. A combined area table/domain table (ATDT) is accessed using destination information associated with a fiber channel packet. Area/port or domain information can be used to address entries in the ATDT. Each entry provides one or more paths to a given destination. Traffic shaping, load balancing, and other policy based forwarding considerations can be applied.

  • Publication number: 20070127396
    Abstract: According to the present invention, methods and apparatus are provided to improve the link state routing protocol (LSRP) to prevent transient loops during topology changes. Broadcast and shared multicast traffic may be dropped on particular ports upon detecting link state change until neighboring nodes have computed routes using updated link state information. An acknowledgment is sent upon receiving a link state record. Sync and sync-ack packets are used to determine when link state information is synchronized with that of peer nodes.

  • Publication number: 20070127395
    Abstract: According to the present invention, methods and apparatus are provided to improve the link state routing protocol (LSRP) to prevent transient loops during topology changes. Broadcast and shared multicast traffic is dropped upon detecting link state change until neighboring nodes have computed routes using updated link state information. An acknowledgment for a link state record is sent only after route computation is complete using updated link state information.
