    摘要： A scalable network architecture adapted to interface with various sensor types and sensor access mechanisms while providing real-time access to sensor data for distributed applications and organizations is described. A centralized sensor network service manages the registration, capabilities, near real-time status of the sensors and their current network connections. New sensors are discovered automatically through messaging between network access nodes and the sensor registry. The registry service can be made available to distributed sensor applications and sensor middleware, and facilitates the sharing of sensors across organizations. The sensor registry is automatically updated by network software and does not require manual configuration or reconfiguration each time a sensor is added to or relocated within the network. Authentication and authorization policies can be implemented to ensure that only authorized applications can query and view the registry. The registry can be implemented for multi-vendor sensor networks and can accommodate multiple addressing schemes.

    摘要： Techniques disclosed herein include systems and methods for providing a scalable solution to transmit edge IP Multicast sender information in a Shortest Path Bridging (SPB) network. Control information is exchanged between Ingress Backbone Edge Bridges and Egress Backbone Edge Bridges using Multicast Flow Specific and type-length-value (TLV) structures, or other control messages, to announce available multicast streams at ingress nodes within the SPB network. Such exchanges of control messages trigger sending SPB specific Intermediate System To Intermediate System (IS-IS) TLV control message with path computation information via IS-IS control messages. This second set of control messages is exchanged within the SPB network and includes source-specific multicast stream information that is used by Backbone Core Bridges to establish a multicast forward state and compute multicast forwarding paths. Multicast data traffic can then be transmitted through the SPB network using a one-to-many distribution model.

    摘要： A method of fabrication of the write head of a perpendicular recording head allows for production of P3 pole tips of width less than 200 nm (200×10−9 meters). The method includes fabricating the P2 flux shaping layer, depositing the P3 layer, depositing a layer of ion-milling resistant material, depositing at least one sacrificial layer, shaping the P3 layer into P3 pole tip, removing the at least one sacrificial layer to leave the P3 pole tip, and encapsulating the P3 pole tip.

    摘要： A method, apparatus and computer program product for distribution of routing information used in a transport network is presented. In a transport network having a plurality of edge devices and core devices, a main instance of a protocol is used for shortest path and tree computation. A multicast tree is defined per Virtual Services Network (VSN) to distribute Link State Data Base (LSDB) updates that only apply to members of said VSN. Multicast trees are built using a secondary instance of the control protocol LSDB and wherein each VSN multicast tree represents a separate instance of the secondary instance of the control protocol LSD. LSDB updates are distributed that only apply to members of the VSN using the multicast tree for the VSN.
