Re: [storm] I-D Action: draft-ietf-storm-rdmap-ext-01.txt

In looking at the changes in this draft from the -00 version, I noticed something that needs attention, although it was already present in the -00 version:

The term "naturally aligned" needs to be defined for buffer addresses, because failure to use a "naturally aligned" buffer address causes a "Catastrophic Error" at the recipient.  For this reason, there needs to be a tight specification of what the sender needs to do to avoid that error.  Specifying a boundary that is always "naturally aligned" (e.g., 64-bit) should suffice (and is probably superior to providing a way to figure this out on-the-wire).

Thanks,
