Re: [STDS-802-3-EPOC] Question on FER Objective
Tom,
That is really interesting - I assume that they were running 2k payloads
(mini-jumbo-frames) and then adding tagging on top of it. I do not really
see how one can get to 2080 octet frames from 1.5k payloads with just VLAN
tags - it is a lot of VLAN tags to put (100+)

I had to work with JDSU to develop a test access system for cell tower and
one of the tests required by the carriers was frame loss ratio. That test
required that test what I would call standard frame sizes to be tested (64,
128, 256 etc ) transported through a network that had to pass a frame 2080
in size. Yes that was a little odd but the carrier was doing a couple of
other things that needed to be supported. To that end though when the
testing failed it was usually the smaller frames not the larger ones.

Mark, Victor, Marek, Duane,
Thanks for the feedback. It sounds like the worst case is
2000 bytes, which is what I would have guessed
Thanks,
Steve

All,
I would assume 64-2000 bytes.

Hi Steve,
Likely we probably all assumed 64 octet to ~1518 octet Ethernet packets and
probably should discuss up to 2000 octets.
I'm assuming others will comment on this.
Cheers,
Mark

Mark, et. al.,
In our Objectives it says we have a frame error ratio (rate)
of 10^-6 on the downstream and 5x10^-5 on the upstream,
http://grouper.ieee.org/groups/802/3/bn/EPoC_objectives_update_1115.pdf
In 802.3 what frame size is used in this objective?
Thanks,
Steve
