Open issue #9: Dead Peer Discovery Issues: Dead peers (e.g., AR (or FA), CRN, HA, CN or MN ) can occur because either a link or a network node failed, or MN moved away without informing NTLP/NSLP (e.g., QoS- or NAT/FW-NSLP). GIST may detect the problems after some time: it says that GIST discovery might be slow (?). Question: How can dead peers be detected in a fast and efficient manner in mobility scenarios? Or, GIST discovery? Do some “dead peer” cases need to be identified in more details? e.g., MN’ moving-away, CRN failure, CARs’ failure, FA/HA’s failure, and so on. |
