AP P LI CAT I O N N OT E | I N V E S T M E N T I N D U S T RY Optimizing Performance of Latency-Sensitive Market Trading/Exchange Applications Identifying and analyzing response time, micro bursts and sequence gaps to ensure application availability Introduction In today’s world of electronic trading, “a millisecond advantage in trading applications can be worth $100 million a year to a major brokerage firm.” (“Wall Street’s Quest to Process Data at the Speed of Light,” Information Week, April 23, 2007) The ability to identify and monitor critical market trading applications and protocols, such as FIX, Multicast, TIBCO and others is essential to the day-to-day operation of financial exchanges, trading houses, hedge funds, investment banks and other global financial institutions and market exchanges with trading desks. Challenges All trading companies share a common need: to keep up with growing market data and Cases inin Point Cases Point transaction rates and to operate with near-zero latency. Increased competition, higher market data volume, the move to start quoting in penny increments, and new regulatory demands are some of the driving forces behind industry changes. Firms are trying to maintain their competitive edge by constantly adapting their trading strategies and n An East Coast financial increasing the speed of trading. To support this new era of electronic trading, many firms are institution was experiencing bolstering their IT infrastructures with bigger “pipes” capable of handling the forthcoming intermittent delay with one of its data influx, as well as providing better, more granular visibility into those larger pipes. market data applications. Using Meeting the Need the nGenius System’s response time analysis capabilities, they NetScout’s Sniffer and nGenius solutions work in combination with strategically deployed monitoring devices and continuous capture appliances to provide a cost-effective approach were quickly able to determine to managing the performance of key business applications that end users and customers delay was attributable to the rely on. The NetScout solutions support the most complex network configurations, including server, not the network. converged and MPLS networks, to deliver comprehensive, real-time network monitoring, application profiling, troubleshooting, capacity planning and user experience assurance n SIAC, which runs the networks capabilities to the network professional. and computer systems used by NYSE and AMEX, uses Sniffer The flexibility of the NetScout Sniffer and nGenius systems enables visibility into the core, distribution and access layers of the network and across both LAN and high-speed WAN distributed monitoring devices environments, including their associated virtual network segments (i.e., VLANs, PVCs and to centrally monitor and manage DLCIs). To meet the challenges associated with converged networks, NetScout displays remote network locations. virtual circuits and their associated QoS simultaneously, ensuring that data, voice and video When a customer experience applications are properly mapped to the right QoS class and that the network is properly difficulty they use Sniffer filters configured to meet business needs. In addition, by utilizing site monitoring capabilities, to observe and troubleshoot the investment services firms can gain complete visibility into remote locations on the MPLS network from a WAN perspective, providing the much needed application-level visibility for data streams. capacity planning and troubleshooting that is commonly masked with MPLS. In short, NetScout Sniffer and nGenius solutions make it easy to maintain consistent real-time analysis and historical reporting of all traditional and market trading-specific applications, all conversations, link utilization and all hosts, regardless of the underlying transport technology in order to meet today’s tough network performance challenges.
