Selective tunneling of streaming data
InactiveUS6189039B1Spread the wordImprove bandwidth utilizationSpecial service provision for substationMultiple digital computer combinationsStreaming dataData stream
A method and system for "selective" tunneling of streaming data from a server to a client in a computer network having one or more network segments. The server has a tunneler utility, and the client has a receiver utility. The receiver utility first attempts to detect if a given data stream is available via IP multicast on the network segment supporting the client. If not, then the receiver utility issues a request for a IP unicast stream. This request is serviced by the tunneler utility. The tunneler utility re-broadcasts the IP multicast feed using IP unicast to send the data stream directly to the requesting user and / or to a repeater utility. The receiver utility then receives and processes the data stream for output to the end user. Alternatively, the receiver application, or a network administrator, launches the repeater utility, which then converts the IP unicast stream back to IP multicast format for re-broadcast over the network segment to other clients.

Establishing consistent, end-to-end protection for a user datagram
A method, system, and computer program product for providing consistent, end-to-end protection within a computer network for user datagrams (i.e. packets) traveling through the network. The network may comprise network segments that are conventionally assumed to be secure (such as those found in a corporate intranet) as well as network segments in non-secure networks (such as the public Internet or corporate extranets). Because security breaches may in fact happen in any network segment when datagrams are unprotected, the present invention discloses a technique for protecting datagrams throughout the entire network path by establishing cascaded tunnels. The datagrams may be exposed in cleartext at the endpoints of each tunnel, thereby enabling security gateways to perform services that require content inspection (such as network address translation, access control and authorization, and so forth). The preferred embodiment is used with the “IPSec” (Internet Protocol Security Protocol) and “IKE” (Internet Key Exchange) protocols, thus providing a standards-based solution.

HyperLock technique for high-speed network data monitoring
In one embodiment, a network architecture includes a plurality of application monitoring modules for monitoring network traffic data in a plurality of network segments. Network monitoring modules include a staging area that receives network traffic data from a packet capture and analysis engine and an indexing area that stores the data in meta-flow tuples with associated measures divided into time interval buckets. Index tables store dimension-based sorted pointers to the storage locations in the data buckets. HyperLock queries collect time aggregated results for measure based operators with respect to a queried dimension. For each value of the queried dimension, the time interval buckets are traversed compiling a partial result that is finally stored in a stack as the time aggregated value. The stored sorted pointers are used to determine the starting location in each bucket with respect to the next value of the queried dimension.

Methods and apparatus for performing handoffs in a multi-carrier wireless communications system
ActiveUS7212821B2Minimize service disruptionMinimize disruptionTime-division multiplexRadio/inductive link selection arrangementsCommunications systemNetwork link
A mobile communications device initiates a handoff from its current base station (BS) sector network attachment point to a new BS sector. The mobile sends a handoff request over its current wireless link to the current BS sector, which forwards the request to the new BS sector, e.g., via a network link. The new BS sector processes the request assigning dedicated resources, e.g., an identifier and dedicated uplink segments. Information identifying the allocated resources is conveyed from the new BS sector via the current BS sector to the mobile. The mobile determines the time of the allocated dedicated segments based upon a received beacon signal from the new BS sector with known timing relationships to dedicated segments. The mobile breaks the original wireless link just prior to the time of the first assigned dedicated segment. The mobile communicates information on the assigned dedicated segments to perform registration operations, e.g., timing synchronization and power control, establishing a new wireless link.

A visualization method for a hub network configuration allows exploration of a chosen network by way of a graphical display interface (GUI), wherein multiple distinct network segments such as lines or rings are shown attached to a common node or centralized hub. The technique combines a graphical view of the segments controlled by a segment selector. The selector is coupled to a series of display indicators and a list of the attached rings contained in the network. The list can contain descriptive elements of the segments, or can provide links to such detail. A mutually exclusive selection of the attached segments is enabled using either the selector or the list of attached segments. For each segment selected, the display indicators can show the currently displayed segments on the GUI, help to highlight on the GUI a selected attached segment and provide an indication of attached segments that are related in function to the selected segment. Selected and remaining segments of the network are displayed in various shadings or colours, which enables a Network Manager or other user of the system and method to easily distinguish and consider these aspects alternatively. In the graphical view, attached segments can be displayed in stacked, overlaid, or isolated formats. The segments can consist of rings, lines, stars, bars, and chains.

Some embodiments provide a novel method for forwarding a packet at a first managed interconnection switching element in a managed network of interconnection switching elements. The method receives a packet from a source machine on a first network segment in a first network. The packet identifies a destination machine located on a second network segment in a second, different network. The method removes a context tag that identifies the first network segment. The method uses the identification of the first network segment to determine a logical switching element that connects at least the first and second network segments. The method encapsulates the packet with a logical context identifier that identifies a logical port of the logical switching element. The logical port corresponds to the second network segment. The method transmits the twice-encapsulated packet towards a second managed interconnection switching element at the second network.

Automatic Configuration of Synchronous Block Execution for Control Modules Run in Fieldbus Networks
ActiveUS20080249641A1Easy and optimal useFaster rateComputer controlSimulator controlProcess control networkAuto-configuration
A method or apparatus automatically configures a control module for synchronous execution on a Fieldbus segment of a process control network by determining if all of the critical function blocks of a particular control module can be assigned to FOUNDATION® Fieldbus field devices or to the I / O device associated with a particular Fieldbus segment. If so, the method or apparatus automatically assigns the function blocks of the control module, which would otherwise be scheduled to execute in a controller, to the I / O device for the Fieldbus segment. This technique enables all of the critical or necessary function blocks within the control module to execute in one macrocycle of the Fieldbus segment, thereby executing synchronously on a Fieldbus segment. This operation, in turn, increases the overall execution rate of the control module with respect to control modules that have function blocks split between a controller and field devices on a Fieldbus segment, which has been the traditional manner of configuring control modules implemented using devices on a Fieldbus segment.
