  • Fault-tolerant central ticker plant system for distributing financial market data
    Patent number: 5987432
    Abstract: A central ticker plant system for distributing financial market data that receives ticker feed data from many exchanges throughout the world, processes and formats the received data and then distributes or broadcasts the data to regional customers in the form of securities transactional data denoting the security identity and related transactional data. The central ticker plant system is fault-tolerant because of novel hardware redundancy and multi-thread software processing architecture and operates continuously during hardware and software maintenance and repair, ensuring that every financial market data message received from the exchanges is included within 500 milliseconds in broadcast output.
