Brief network notes from E3D stakeholder meeting
by Lars Fischer 17 Oct '19

17 Oct '19

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. -- Lars Fischer - Strategy & Policy, NORDUnet <lars(a)nordu.net>, +45 2288 1729, @lpfischer

Travel, E3D stakeholder meeting, Tromsø
by Lars Fischer 29 Sep '19

29 Sep '19

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. /Lars -- Lars Fischer - Strategy & Policy, NORDUnet <lars(a)nordu.net>, +45 2288 1729, @lpfischer

CANCELLED - EISCAT-3D network status meeting
by Lars Fischer 12 Feb '19

12 Feb '19

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. /Lars -- Lars Fischer - Strategy & Policy, NORDUnet <lars(a)nordu.net>, +45 2288 1729, @lpfischer

E3D ring w/o FI & SE local loops / sites
by Lars Fischer 24 Oct '18

24 Oct '18

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. /Lars -- Lars Fischer - Strategy & Policy, NORDUnet <lars(a)nordu.net>, +45 2288 1729, @lpfischer
