    摘要： Enhancing performance in a multicasting system comprising monitoring filtering costs in a multicasting system as system characteristics change over time, wherein the multicasting system is operating based on a first mapping, between a plurality of data flows and multicasting groups, to disseminate data to users that subscribe to one or more of the data flows; computing a second mapping in response to determining that overhead associated with filtering of unwanted flows at the user level has exceeded a threshold; and transitioning the multicasting system from using the first mapping to using the second mapping, in response to determining that the second mapping is feasible as applicable to one or more constraints associated with the multicasting system.

    摘要： A method for migrating data transmitted from a transmitter to a receiver over a first stream to a second stream in a reliable multicast system is provided. The method comprises transmitting a first message from the transmitter to the receiver over the first stream to notify the receiver that a first data flow transmitted on the first stream will be transmitted on the second stream. The transmitter transmits a second message to the receiver over the second stream after a second threshold has expired. The receiver tunes to the second stream based on the second message. The transmitter transmits a third message to the receiver over the first stream after a third threshold has expired to notify the receiver that transmission of the first data flow over the first stream will be terminated. The transmitter then transmits a fourth message from the transmitter to the receiver over the second stream after a fourth threshold has expired.

    摘要： Selecting application messages from redundant feed adapters for application-level data processing in a high speed, low latency data communications environment, including brokering establishment of an active message stream to a subscribing client device from an active feed adapter; brokering establishment of a backup message stream to the subscribing client device from a backup feed adapter; receiving active transport packets in a transport engine of the subscribing client device from the active feed adapter; receiving and buffering backup transport packets; identifying a missing active transport packet; determining whether a corresponding backup transport packet for the missing active transport packet has been received from the backup transport adapter; and replacing the missing active transport packet with the corresponding backup transport packet for further data processing if the corresponding backup transport packet for the missing active transport packet has been received.

    摘要： A publish/subscribe system includes a publisher and multiple subscribers. The published includes a packet generator to generate a packet with at least one of: a fixed length flow label labeling a message or a message bundle and a fixed length node label labeling at least one message bundle and indicating at least one of the nodes of a topic tree to which the flow label belongs. Each received includes a user selection data holder and a message selector. The data holder stores a selection of topics of interest to a user from the topic tree. The message selector receives a packet having a header and data, determines which flow and/or node labels are incorporated in the header and accepts the data if the user selection data holder indicates that the labels within the header are of interest to the user.
