When dealing with an application where degradations of milliseconds could severely impact the financial outcome, more effective approaches are necessary. Maintaining network performance for critical trading applications means detecting, diagnosing and rectifying issues that may impede their delivery. In market trading firms, this means identifying, in the earliest stages, problems with packet loss, out-of-sequence packets, latency or delay. The nGenius Solution is well positioned to monitor all the traffic in the network to quickly recognize a number of potential Microburst alarms are available in real-time, provide the application and conversation details for the signs of network degradations.
