Abstract: Methods and systems for information dissemination in mobile ad hoc networks founded on Content Based Routing. The method comprises encoding, via an encoding logic within the source node, a plurality of information categories associated with the content in a header of the packet, encrypting the packet with an encryption key unique to the plurality of information categories, with the encrypted packet having a unique dissemination group identity in its header, and disseminating the encrypted packet to nodes that have subscribed to the data based on the dissemination group identity. The system comprises a host within the source node, an identity generator to generate the dissemination group identity for the content, an encryption unit for encrypting the content, and a routing unit to disseminate the content to the dissemination mesh based on established subscriptions.

Abstract: The present invention describes methods and systems for information dissemination in mobile ad hoc networks founded on Content Based Routing. The method comprises generating a first data packet at a source node, encoding, via an encoding logic within the source node, a plurality of information categories associated with the first data packet in a header of the first data packet, encrypting the first data packet with an encryption key unique to the plurality of information categories, generating a second data packet having a unique dissemination group identity in its header and the encrypted first data packet as a payload of the second data packet, disseminating the second data packet across a dissemination mesh, and receiving the second data packet at a destination node.

Abstract: A distributed software application comprises a first and second software component. A manager component of a management infrastructure for the distributed software application in one example causes a first software component of the distributed software application to obtain information from a second software component of the distributed software application for initialization of the first software component.

Abstract: An apparatus in one example comprises a manager component that upon receipt of an indication of a need for a communication channel between a first software component and a second software component, instructs management support software of the first software component to set up the communication channel between the first software component and the second software component.

Abstract: An apparatus in one example comprises a manager component for a distributed software application that based on one or more of a characteristic of an executable of the distributed software application and/or a characteristic of one or more of a plurality of processors, selects a processor from the plurality of processors to run the executable upon startup of the distributed software application.

Abstract: A manager component of an apparatus in one example initializes a plurality of software components of a distributed software application, within one or more executables, in an ordered sequence based on one or more dependency relationships among the plurality of software components.

Abstract: An apparatus in one example comprises a manager component in communication with a distributed software application. The distributed software application comprises a plurality of software components that run within one or more executables. The manager component shuts down the plurality of software components in an ordered sequence based on one or more dependency relationships among the plurality of software components.

Abstract: A distributed software application comprises a plurality of software components within a plurality of executables. A manager component for the distributed software application performs a recovery of two or more software components, of the plurality of software components, in an ordered sequence based on one or more dependency relationships among the plurality of software components.

Abstract: The present invention provides a network support mechanism, called Sync-VPN, that is transparent to real-time, multi-user distributed applications, such as online multi-player games in which the order of player actions is critical to the outcome. The invention uses a client/server application model, where a server coordinates state updates based on action messages sent by clients. The invention builds on bandwidth-quaranteed VPN service to ensure predictable packet delay and loss characteristics, thereby providing predictable packet service, state update fairness, and player action fairness. A Sync-out mechanism synchronizes delivery of state updates to all players enabling them to react to the same update fairly. A Sync-in mechanism processes action messages from all players in a fair order based on real-time occurrence. Sync-VPN employs a round-trip time estimation algorithm essential to message latency estimation in the Sync-out and Sync-in mechanisms.

Abstract: The present invention addresses the shortcoming of the prior art by providing a network support mechanism that is transparent to real-time multi-user distributed applications. In particular, the proposed invention is well suited for the type of online multi-player games in which a fair order of player actions is critical to the outcome. Without fairness support, remote players often receive much delayed data to act on, and their actions cannot compete in time with other players. The present invention proposes a network support mechanism, called Sync-VPN, for real time multi-user distributed applications such as multi-player online games. The approach assumes a client/server application model, where the server is responsible for coordinating state updates based on action messages sent by the clients. The approach addresses three desired features: predictable packet service, state update fairness, and player action fairness.

Abstract: A network management system (NMS) and method is arranged for monitoring, controlling and managing a network that includes a set of interconnected network elements (NEs). A management agent in each NE interacts with the NMS on behalf of the NE. The system and method utilizes (a) a behavior transition model based on NE status or “health” indicators for passive monitoring, (b) a status updating mechanism with adjustable or “tunable” parameters based on operating conditions, (c) a derivation procedure for correlating ripple effects, and (d) an early-warning model for proactive management.

Abstract: A method of delivering highly-reliable, fault-tolerant communications services in a telecommunications network of distributed call processing systems. The method advantageously identifies a set of objects within the telecommunications network requiring checkpointing; checkpoints the objects; and subsequently restores the checkpointed objects in the event of a failure. Various aspects of the method are disclosed, including restoration strategies.
