Technical Summary

  This draft describes a method of detecting a dead IKE (Internet Key
  Exchange) peer.  The method, called Dead Peer Detection (DPD), uses
  IPsec traffic patterns to limit the number of IKE messages sent.  DPD,
  like other keepalive mechanisms, is often necessary to perform IKE
  peer failover, or to reclaim lost resources.
