SELECTING APPLICATION MESSAGES FROM AN ACTIVE FEED ADAPTER AND A BACKUP FEED ADAPTER FOR APPLICATION-LEVEL DATA PROCESSING IN A HIGH SPEED, LOW LATENCY DATA COMMUNICATIONS ENVIRONMENT

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.
