  1. NETEXT WGIETF 82 Service Selection for Mobile IPv6 RFC5149bis WEDNESDAY, November 16, 2011 JouniKorhonen

  2. Background • RFC5149 was defined for RFC6275 (MIPv6) and RFC5213 (PMIPv6). • There are known implementations for PMIPv6 (yes, live deployments and multiple vendors). • RFC5149 has few areas that the authors think need enhancing & clarifications. • RFC5149 is Informational, however the authors feel it should already be Standards Track.

  3. RFC5149bis – change summary • Echoing the Service Selection option in (P)BAs– this is what running code does. • Updates to RFC5213 BCE lookup considerations. The Service Selection is used as one lookup key – this is what running code does. • New Status Code: MISSING_OR_UNKNOWN_SERVICE. • Different from SERVICE_AUTHORIZATION_FAILED, which is not a good for a case where the requested service is not known the HA & LMA – this is what running code does. • Updating the document category from Informational to Standards Track. • Multiple implementations, deployed, operation experience, ...

  4. For [discussion] • Some deployments encode the Service Selection Identifier field using RFC1035 style domain name encoding.. should that be described somehow? Current“standard” encoding is UTF-8. • How to extend Identifier with an additional “index” for a case where: • The same service is accessed multiple times using the same Identifier name to configure multiple prefixes; example 2x “Internet”. The index allows to distinguish between “services” when prefix is not available (handoff). • This was proposed at the early stages of RFC5149 but removed. However, it isnot trivial to add such “index” now (backward compatibility). • Existing deployments have such but those chose not to “decorate” the Identifier and instead useRFC5094 VSMs.

  5. Questions & Next Steps • Adopt as a WG document?
