Experimental/private join attributes

Experimental/private join attributes. Current join attribute registry. 64 code points, used 4 so far Explicit RPF and LISP join attributes use 3 more. Allocation based on IETF review RFC needed (I believe), but may get early allocation when document is stable

Presentation Transcript

  1. Experimental/private join attributes

  2. Current join attribute registry • 64 code points, used 4 so far • Explicit RPF and LISP join attributes use 3 more. • Allocation based on IETF review • RFC needed (I believe), but may get early allocation when document is stable • Fairly strict, no code points available for experiments or private use • Make it more liberal? • Concerns with supporting attributes that have not had sufficient review?

  3. Experimental code points? • What if someone wants to experiment with a new implementation/protocol requiring a new code point? • RFC 3692 recommends having at least one value for experiments • For experiments only, should not be used in products. Different experiments are likely to use the same value, hence not for general deployments. • Should be ignored by default

  4. Private code points? • Set aside some attributes for more private use? • Less strict, e.g. require documentation? • Registry needed to avoid conflicts? • Expand the type space? • Or do we believe that attributes should be reviewed? • If we allow private code points, would anyone ask for code points that require review?

  5. Encoded-Source Address Encoding Type Field registry • 256 values • 0 is native, 1 for join attributes. • Allocation based on IETF review • Fairly strict, any need for experimental or private use?

  6. draft-atwood-pim-reserve-exp-00 • New draft submitted this Monday • Proposes 2 experimental attribute code points and 4 experimental encondig types • Is this what we want?
