International Classification:

G06F 15/16
G00F 15/173

US Classification:

709245, 709238

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.

International Classification:

US Classification:

715772, 715839

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.

International Classification:

US Classification:

709233, 709228, 709230, 709246

Abstract:

A method includes advertising a policy characterizing communication properties supported by a node. The policy may be distributed to another node in response to a request for the policy. Policy expressions in the policy include one or more assertions that may be grouped and related to each other in a plurality of ways. A system includes a policy generator for generating at least one policy characterizing properties of a node. A policy retriever retrieves a policy from another node and a message generator generates a message to the other node, wherein the message conforms to the policy from the other node.

International Classification:

G06F 3/00

US Classification:

719310

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. Handlers may be automatically created when an event meeting predefined criteria occurs, including the non-occurrence of a condition, making the virtual network self-healing and adaptive to reconfiguration.

International Classification:

G06F 15/173

US Classification:

709223, 726 1, 726 2

Abstract:

A method includes retrieving an intermediate node policy characterizing communication properties supported by an intermediate node, the intermediate node being between a source node and a destination node in a communication path. The method includes forming a first policy-compliant message in accordance with the intermediate node policy, the first policy-compliant message including a request for a destination node policy characterizing communication properties supported by the destination node. A system includes a policy retriever comparing a source policy to one to an intermediate policy to determine whether the source policy is compatible with the intermediate policy. A message generator generates a policy request message by applying the intermediate policy to a request for a policy related to a destination node.

Abstract:

A web services namespace pertains to an infrastructure for enabling creation of a wide variety of applications. The infrastructure provides a foundation for building message-based applications of various scale and complexity. The infrastructure or framework provides APIs for basic messaging, secure messaging, reliable messaging and transacted messaging. In some embodiments, the associated APIs are factored into a hierarchy of namespaces in a manner that balances utility, usability, extensibility and versionability.

International Classification:

G06F 15/16

US Classification:

709246, 709238, 709245

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.
