All, very brief notes from my presentation at the E3D stakeholder
meeting. Slides attached.
/Lars
- Presentation went well; E3D people understood the suggested change
from routed network to point to point, with all traffic going through a
data centre. I believe this was generally accepted as a better way.
- Led to good discussion of picking a data centre, and the important of
doing so early. Craig asked relevant questions on what happens if they
have to move from DC A to DC B
- Craig seem not uninterested in using a data centre on-ring and close
to Tromsø that is becoming available
- Craig appear to be slowing moving away from 90’s style thinking
about computing and network. The NeIC project has been good in this
respect.
- Craig is also considering keeping all data in Skibotn for the first
couple of years. We might like to think about a grow-as-you-go plan
(i.e, from 100G from site to TB from sites, and
Several participants were very interested in the TB/s options and how
that changes long-term computing options.
- I suggested that we stop thinking about the network as a separate
thing, but rather consider it an integral component in the computing -
instrument, site network, site computing, WAN, DC network, DC computing,
storage. The WAN can go anywhere in that picture, really.
- None of this was conclusive. It was a conversation starter. My
immediate guess is that they will go for 2x100G per site now, moving to
much more capacity in the future. Possibly, this will be linked with a
model where they do all computing at Skibotn now, and move to a DC in
2-3 years.

Hi,
I am planning my travel for the E3D stakeholder meeting in Tromsø on
17.10. Am I the only one going from the network side? Should I plan for
side meetings?
I will travel up on the 16th (no morning flight to get me there in
time), and probably back on the morning of the 18th.

All,
Tomorrow (Wednesday) we are scheduled to have a E3D network status
meeting. Unfortunately, when we agreed the meeting I overlooked that
this week is Danish winter holiday week. I, and many others, are away
skiing.
I am therefore cancelling the meeting and will send around a doodle for
new slot.

All,
on 23 October we have a status meeting with EISCAT. One of the
outstanding issues is that we should build a ring, delivering IP service
to Skibotn, by summer 2019, while the two sites at Karesuando and
Kaiseniemi will only be build in 2020.
As there will likely be nothing at the sites (no buildings, no power, no
opportunity to deploy the local loop fibre) by summer 2019, we will have
to initially bypass the two sites.
BJ tells me that for Kaiseniemi, this can be done at the Kiruna pop.
Can you confirm this, BJ?
For Karesuando, I have info so far. The Sodankylä - Skibotn link pass
through the sites, with no PoP or ROADM along the way. Matti, Jani - is
there a way to complete the Sodankylä - Skibotn link without the
Karesuando site and the local loop fiber to the site?
As indicated, it would be best not to have this as an unknown for the 23
October meeting.
