Dead Peer Detection (DPD) is a method of detecting a dead Internet Key Exchange (IKE) peer. The method uses IPsec traffic patterns to minimize the number of messages required to confirm the availability of a peer. DPD is used to reclaim the lost resources in case a peer is found dead and it is also used to perform IKE peer failover.
Famous quotes containing the words dead and/or peer:
“We saw the lightning and that was the guns; and then we heard the thunder and that was the big guns; and then we heard the rain falling and that was the blood falling; and when we came to get in the crops, it was dead men that we reaped.”
—Harriet Tubman (18211913)
“The Peer now spreads the glittring Forfex wide,
Tinclose the Lock; now joins it, to divide.”
—Alexander Pope (16881744)
