  2. Status • The -01 draft was released after the DC IETF meeting. • Tried to clarify various sections, especially those for which we received good input for -00 draft. • We did not receive any comments for -01 draft :-( • The -02 draft was submitted prior to this meeting (IETF-47) • Incorporates most, but not all, of the comments received so far. • Lots of minor edits and wordsmithing plus some sections more heavily revisited. • Completed VSAT example and added text for W-WAN examples, including WAP • We need help filling in some of the sections of the draft (and in addressing some uncovered comments)

  3. Soliciting Input (still) • Additional PEP types and/or mechanisms which should be included in the draft. Some mechanisms already identified and placeholders added: • protocol booster mechanisms • ACK filtering and regeneration (in ASYM) • partial ACK mechanisms ? • others...? • Some additional example environments where PEPs are used may be added. • However, we are not trying to describe every PEP implementation in existence. So, proposals illustrating types or mechanisms of PEPs other than those illustrated by the existing examples are favored • Need help in completing the section on WAP.

  4. Soliciting Input (Cont.) • Most importantly, we are currently soliciting input on (additional) implications of using PEPs. Some ideas already suggested (placeholders exist) which need to be flushed out (or need additional flushing out): • End-to-end failure diagnostics • Multi-homing environments (got comment in Oslo, but no input) • QoS transparency (got comment in Oslo, but no input) • Any other security implications besides those currently included • Others ? (Aren’t there any?) • Terminology refinement
