Service disruptions are quickly noticed, especially when repeated. Consumers can and will switch providers at the drop of a packet. In the multiplay networks of today, it is essential that we consider service interruption time with respect to traffic type. Convergence time is one of the key performance indicators (KPIs) in modern high-availability networks that carry multiplay traffic. Classical techniques for measuring convergence time in all-data networks are no longer adequate for measuring the quick, sub-50-millisecond convergence times in modern networks. In this informative white paper, Measuring Network Convergence Time, Ixia discusses convergence and convergence testing to provide service providers and network operators with the insights needed to understand the impact of outages and how it may affect service level agreements (SLA). What You Will Learn: The effect of convergence on different services; The causes of network outages across layer 1, 2, and 3; The next generation protocols that dramatically improve the time to detect and recover from failures at layer 1, 2, and 3; The traditional way to measure convergence and the method Ixia developed to provide you with millisecond-resolution measurements.
