The IPFRR technology provides fast network recovery after a link or router failure within an ISP network. During the link or the router failure within network, there is unpredictable period of time when part of communication is lost until the process of network convergence will complete. During this process specific networks may become unavailable and problems with critical applications and services,...
The OSPF convergence period takes several milliseconds to update the current information about the topology. In worse transient behavior, the packets are dropped or loop may occur. It may result in network instability. The link failure recovery is important because it finds the alternative path to deviate the packets, in order to prevent the packet loss rate. An IPFRR approach, FEPS can handle single...
