Re: [p2pi] WG Review: Application-Layer Traffic Optimization (alto)

["Narayanan, Vidya" <[e-mail]>]

To answer your question about participation, I can definitely volunteer to work on the requirements and solution for this effort.  We will try to produce a draft explaining the problem and need for peer participation in ALTO by the deadline for Minneapolis.

With respect to process, I think this one takes the cake among abominations.  Having been at the IETF long enough and having participated in several BoFs, I'm quite familiar with RFC2418 and the process.  Here we have an effort that started with a closed/gated workshop outside the IETF, was brought into the IETF as a BoF in RAI that ended in an inconclusive manner and transitioned now into a WG proposal for APP with little to no explanation to the wider audience on the rationale.  So, it may be best if we didn't really get into the process discussion with this effort.

I'm just hoping that at this stage, the ADs are going to hear all opinions and also use technical judgment on the relative points that are being made.

Best regards,
Vidya
