  6. IP policy • A SC is covered by the WG IP policy announcements. • Even though we don’t have to read the policy to SC attendees, all attendees are reminded that the policies are in effect and apply to SC sessions. David Bagby, Calypso Ventures, Inc.

  7. Advice Request • MIBs • Topic prompted by email from Adrian Stephens • Email fwd’d to Arc list • Discussion • Adrian gave intro to issues he sees. • Some historical perspective given by Darwin • ASN1 in annex D used to define MIB vars (.1 influence) • Unclear rules around what MIB vars are needed and why as amendments were created. Resulted in a mix of assumptions being used by diff TGs. • Read / write vs static/dynamic variables/capabilities (ex: rx STBC) • Make internal vars not = MIB vars? Split into diff category? • Current spec readers assume all mibs vars are interfaces to an entity… David Bagby, Calypso Ventures, Inc.

  8. MIBs (continued) • Exercises which might help • Classify mib vars into capability, status, control knob, “confused/mixed perceptions” • Internal/external to an entity (entity is a block in a pic in the std) • Int/ext to what entity? • Ext => there is a protocol that communicates this between entities. • Issue: “implicit vars”; ex: tgn:” sta whose last xmitted ht op element had field x set to value Y….” • No deterministic relation between get/set of mib var and some associated action internal to an entity. • (ex: frag threshold) • This all will begin to beg for a definition of the SME and what it does…. David Bagby, Calypso Ventures, Inc.
