International Classification:

G06F 11/20

US Classification:

709232, 709223, 709227, 709231

Abstract:

A method includes receiving active application messages that are part of an active message stream in a subscribing client device from an active feed adapter. Each active application message is characterized by an active source stream identifier, an active source stream sequence number, and an active message sequence number. The method includes receiving, in response to a failover from the active feed adapter to a backup feed adapter, backup application messages in the subscribing client device from the backup feed adapter. Each backup application message is characterized by a backup source stream identifier, a backup source stream sequence number, and a backup message sequence number. The method includes administering, by 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.

G06F 15/16

US Classification:

709227

Abstract:

Methods, apparatus, and products are disclosed for reliable messaging using redundant message streams in a high speed, low latency data communications environment that include 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; brokering, by the 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 messages; receiving the active messages in messaging middleware of the subscribing client device; receiving, in response to a failover, the backup messages in the messaging middleware; and administering, by the messaging middleware, the backup messages in dependence upon an active stream source identifier, an active stream source sequence number, a backup stream source identifier, and a backup stream source sequence number.

US Classification:

719313

Abstract:

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.
