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.
