Goal • Avoid reauthentication from scratch by transferring PANA context between PAAs • Define PANA context • Define how to use CXTP for this IETF65 - PANA WG
Issue #1 • Issue: Session-Lifetime Elapsed • (not sufficient for the nPAA) • Proposal: • Change « Session-Lifetime Elapsed » by « Session-Lifetime Remaining » IETF65 - PANA WG
Issue #2 • Issue: How do pPAA get nPAA ID ? (necessary for AAA-Key-int computation) • Proposal: • Add nPAA ID in the CDB (by TLV) • Add text accordingly IETF65 - PANA WG
Issue #3 • Issue: Add details on how the PSA message is sent between nPAA and pPAA • Proposal: • Add text to define the CDB and FPT (CXTP terms). IETF65 - PANA WG
Issue #4 • Issue: Identifier for the CTD received by nPAA (match request and response) • Proposal: • Use the MN’s pCoA field of the CT-Request message • Add an Applicability Statement (« …This proposal MUST only be used for PANA… ») IETF65 - PANA WG
Next Steps • AAA interactions • AAA infrastructure needs to know PAA in charge of the PaC (reauthentication/session management) ? • Need discussions • PANA-Mobopts document ? IETF65 - PANA WG
