The IESG has approved following document: - 'A Traffic-Based Method of Detecting Dead IKE Peers ' <draft-ietf-ipsec-dpd-04.txt> as an Informational RFC This document is the product of the IP Security Protocol Working Group. The IESG contact persons are Russ Housley and Steve Bellovin. 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. Working Group Summary The IPsec Working Group came to consensus on this document. Protocol Quality This document was reviewed by Russell Housley for the IESG.
