In-network real-time performance monitoring with distributed event processing

A key important issue for telecom management is the delay in comprehending network conditions. This delay harms precise network management activities because the amount of managed data required for performance management has been increasing due to emerging technology such as the virtualization tailoring dedicated network service for an enterprise. Hence, the increase in managed data is accelerating, and in future, we will see a fatal limitation of the current management approach. Timely monitoring of failure is increasingly valuable. To tackle this issue, a decentralized performance management system is assumed, and a real-time performance monitoring implemented inside distributed network devices is proposed. In the system the demonstration result shows that burst traffic was successfully detected at 250 millisecond intervals, and a detection resolution of its failure is significantly improved, compared with the conventional centralized management approach.
