Measuring Network Convergence Time

White Papers

Introduction to Convergence


Convergence addresses the manner in which networks recover from problems and network changes. Modern networks anticipate problems by providing alternate, redundant or standby paths. Failover is the process in which networks automatically detect service interruptions and adjustments and switch over to an alternate path. Convergence is the event that happens within the transport network when the re-routed information flow merges back to a point in the errorfree path. Failback, conversely, is the process of restoring a network back to its original state when the service interruption is fixed.
