Short Summary

• Goal
• Proposing one concrete procedure of pre CRN
  discovery for fast state installation (establish
  new path before MN actually moves)

• Solution
• Utilizing Proxy (NSIS-aware NAR)
• Proxy receives current flow ID and session ID
  from MN, which are currently used between MN and
  CN
• The proxy exchanges messages with CN, which
  containing the session ID and flow ID pair to
  gather overlapping paths information
• By analyzing the overlapping paths information,
  the proxy knows CRN (for both uplink and downlink)

Open issues

• How it works with QoS-NSLP ?
• Would it be possible to add some functionalities
  to QUERY or RESPONSE or NOTIFY?
• How it works with NTLP/GIMPS?
• How it works with mobility protocols?
• Security?

Thank You!
