1. A method of reliable messaging using redundant message streams in a high speed, low latency data communications environment, the method comprising;

  • brokering, by a stream administration server, establishment of an active message stream to a subscribing client device from an active feed adapter, the active message stream capable of communicating active application messages, each active application message characterized by an active source stream identifier, an active source stream sequence number, and an active message sequence number;

    brokering, by the stream administration server, establishment of a backup message stream to the subscribing client device from a backup feed adapter, the backup message stream capable of communicating backup application messages representing duplicates of the active application messages, each backup application message characterized by a backup source stream identifier, a backup source stream sequence number, and a backup message sequence number;

    receiving the active application messages in messaging middleware of the subscribing client device from the active feed adapter;

    receiving, in response to a failover from the active feed adapter to the backup feed adapter, the backup application messages in the messaging middleware of the subscribing client device from the backup feed adapter; and

    administering, by the messaging middleware of the subscribing client device, the backup application messages in dependence upon the active stream source identifier, the active stream source sequence number, the backup stream source identifier, and the backup stream source sequence number.
