Achieving faster failure detection in OSPF networks

  title={Achieving faster failure detection in OSPF networks},
  author={Mukul Goyal and K. K. Ramakrishnan and Wu-chi Feng},
With the current default settings of the OSPF parameters, the network takes several tens of seconds before recovering from a failure. The main component in this delay is the time required to detect the failure using Hello protocol. Failure detection time can be speeded up by reducing the value of HelloInterval. However, too small a value of HelloInterval will result in an increased chance of network congestion causing loss of several consecutive Hellos, thus leading to false breakdown of… CONTINUE READING
