    摘要： 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.

    摘要： An inverse query engine that uses an instruction tree to represents the queries to be applied against input, instead of applying each query individually. Each node in the instruction tree represents executable code. Each branch of the instruction tree when executed from the root node to a terminating branch node represents the instructions to be executed to process that query against the input. The instruction tree is forward-only in that once a node in a tree is processed against an input, that executable code associated with that node is not ever processed again for that node. Accordingly, processing resources and time is conserved.

    摘要： The present invention extends to methods, systems, and computer program products for using distributed queues in an overlay network. Embodiments of the invention can be used to replicate queue state (e.g., inserted and/or deleted messages) within an overlay network and can be used to continue a process at a different node within the overlay network based on replicated queue state. Accordingly, embodiments of the invention can be used to increase the availability of queue state, compensate for node failures within an overlay network, and promote replication of consistent queue state between nodes within an overlay network.

    摘要： The present invention provides for a channel model capable of generating a runtime communication channel with pluggable modular channel components. These channel components implement one of a set of standard interfaces that allow processing details of communication semantics between components to be represented in a polymorphic way. A message and corresponding communication semantics are recursively passed through the channel components using the standard interface, thereby abstracting other modules and components from specific implementation details of how the communication semantics are performed. The message may then be sent to the next appropriate module for further processing, or the processing may be completed at that particular component or module. Note also that the message can also be de-multiplexed on the service side in a similar fashion as that described above.

    摘要： The present invention extends to methods, systems, and computer program products for using HyperText Transfer Protocol communication as a transport for bi-directional data streams. Embodiments of the invention facilitate passing otherwise blocked TCP communication through a firewall. Embodiments of the invention can be used to pass legitimate TCP communication through a firewall even though a firewall is configured to block the legitimate TCP communication.
