  • Patent number: 8429554
    Abstract: Displaying graphical indicators, instead of data, based on user-defined conditions. The user can specify conditions for displaying graphical indicators instead of actual data by specifying a test, values, and an image. The graphical indicators can be pre-assigned images that are dynamically applied based on the underlying text or numeric data values. Graphical indicators allow the user to visually represent data types or categories with graphics, based on the user's conditions. Different conditions can be specified for a given data field and each condition can be associated with a particular graphical indicator. Prioritized processing of data conditions allow for complex control of which indicator will be displayed to visually represent the data. When the underlying data in a field changes, the criteria can be reapplied and the field dynamically updated to the appropriate indicator.

  • Patent number: 7899047
    Abstract: Methods and systems for providing a virtual network are disclosed. At least one layer of abstraction is created between network service applications and conventional network protocols by inserting an adaptive dispatcher between applications and network transport services on each machine in a network. The message protocol in the virtual network is extensible, allowing application programs to create new headers within any message as needed. The adaptive dispatcher contains handlers that route and dispatch messages within the virtual network based on arbitrary content within each message, including any combination of headers and/or data content. Each device on the virtual network has a virtual address to which messages are directed, allowing devices to move within the network without reconfiguring routing tables.

  • Patent number: 7676540
    Abstract: Methods, systems, and data structures for communicating object metadata are provided. A generic metadata container is presented that allows object metadata to be described in an extensible manner using protocol-neutral and platform-independent methodologies. A metadata scope refers to a dynamic universe of targets to which the included metadata statements correspond. Metadata properties provide a mechanism to describe the metadata itself, and metadata security can be used to ensure authentic metadata is sent and received. Mechanisms are also provided to allow refinement and replacement of metadata statements. The metadata container may be used to convey referral data to update routing tables in network nodes, and may also be used register referral statements and query a node for referral information.

  • Patent number: 7653747
    Abstract: An apparatus and method is provided for resolving virtual network names using one or more name routers. A conventional Uniform Resource Locator (URL) naming scheme is extended by allowing any component to be mapped to an address. The resolution process occurs recursively through a plurality of name routers. Resolution can be contextual, such that the same virtual network name may be resolved differently depending on the identity of the client or other parameters.

  • Patent number: 7565451
    Abstract: Mechanisms in which upon receiving a message, the message is passed through one or more receiving path components that are positioned in the receiving path of the message prior to being passed to a dispatching component. One or more of the receiving path components may modify the message to include information that may be helpful to the dispatching component in order to perform the dispatch. The dispatching component receives modified message, and uses information from the modified message (including potentially the modification itself) to perform the dispatch. Since the message is modified to include additional information helpful to the dispatching component, the dispatching component may be more flexible in identifying the processing that should occur with the message. Accordingly, specialized and flexible processing may be enabled that is ideally suited for the message.
