  • Routing of network messages
    Patent number: 8001189
    Abstract: A routing protocol is provided for exchanging messages between an initial sender and an ultimate receiver, potentially via a set of intermediaries. The routing protocol provides an optional reverse message path that enables two-way message exchange patterns. The routing protocol can be expressed as a header entry within a message envelope, is independent of the underlying protocol, and can be generated at the application layer of a protocol stack. The routing protocol may allow each intermediary to process the message and dynamically alter the message path en route to the intended recipient.

  • Policy algebra and compatibility model
    Patent number: 7584499
    Abstract: The present invention provide for an algebraic mapping of a policy expression from a compact to a normalized form, both in Boolean and set formulations. The policy algebra is defined in such a way that policy alternatives within the normalized expression will be the same across equivalent compact expressions—regardless of how the assertions are arbitrarily constrained or what operators are used to constrain such equivalent expressions. Moreover, the present invention also provides a model for identifying alternatives that are equivalent by comparing only the root element names or QName of each assertion within an alternative. In addition, embodiments as described herein can utilize the identification of equivalent alternatives in order to create an intersection policy expression to limit alternatives of admissible behavior to those in common across both endpoints.

  • Mechanism for preserving session state when using an access-limited buffer
    Patent number: 7565395
    Abstract: Preserving session state correlation in a distributed computing environment in which a service module instance receives messages from a general input buffer. The general input buffer is not accessed by a service module instance once the service module instance is determined to be recycled. After the service module instance receives a session initiation message through the general input buffer, a session-oriented input buffer is associated with the service module instance. Any subsequent session messages are then received by the service module via the session-oriented input buffer. Even if the service module instance was determined to be recycled mid-session, the service module instance would still operate to process all of the remaining session messages from the session input buffer, thereby preserving session continuity.

  • Interface infrastructure for creating and interacting with web services
    Patent number: 7512957
    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.

  • Method and system for measuring network performance from a server
    Publication number: 20030046383
    Abstract: A system and method for measuring the performance of a network, such as the Internet, uses a server on the network to collect network performance data in the process of servicing clients on the network. When the server receives a data transfer request from a client, it records operation information such as the time it takes to transfer the requested data, the size of the data, etc. and derives performance evaluation data such as round-trip time, bandwidth, packet loss, etc. that indicate network performance between the client and the server. The recorded performance data for the multiple clients are aggregated and analyzed together with client information to determine the network performance experienced by the clients.
