RFC: Remote Switch in Duluth
by Richard Laager May 31, 2018

May 31, 2018

The following is from Ryan Goldberg of Compudyne: ---- Compudyne/AS47096 is interested in operating a MICE remote switch in Duluth. We have two 10G paths from 511 to Duluth (one on Charter, one on Enventis) in a ring of 5 Juniper MX boxes (2 at 511, 3 in Duluth – the 3 in Duluth are interconnected over dark fiber). We hit a little over 5G on 5min averages in total between the two 511<->Duluth legs. Latency is 4-5ms. We currently participate in MICE via MNVoip’s extension, mainly because it makes more overall sense to pick up MICE + SIX + Denver + KC all on one interface (for now). We’d probable leave it like that for a while. For the proposed extension switch we’d do a two site VPLS config on the MXes, with on a fresh, dedicated 10gig port at 511 and corresponding 10gig port in Duluth. We’d start with an EX4200-24F in Duluth, and run the usual Juniper-y stuff (from http://micemn.net/technical.html) Initial participants would only be on 1gig ports on the 4200. As for location, we’re currently leaning toward “the Missabe Building” at 227 W 1st St, Duluth, MN – this is our primary downtown Duluth POP, and aside from our fiber, and there’s high-count fiber from at least 5 other carriers in the building. The space has dual AC and is backed by generator power. Upgrade path is 100G 511<->Duluth, at least on one leg. If business drives it, we’ll just do it. Otherwise it’s budgeted for next year. As for the switch, we’d move to a ex4550. ---- Without taking any position on this here yet, I'd like to highlight a couple of facts: The proposed transport is over a VPLS link (i.e. shared with other traffic, not a dedicated wave). In the past, and quite possibly still, we have had participants connected over shared links, but not entire remote switches. -- Richard

Neutral Path link issue between Belle Plaine and MICE
by Frank Bulk May 6, 2018

May 6, 2018

I woke up this morning to see emails about our BGP sessions with MICE to be down. Look at alarms and graphs I see that the link from Belle Plaine to MICE is down since about 12:39 am. According to the NeutralPath NOC (operated by WINS?), something about how a temporary fiber fix for emergency fiber work failed? I wasn't even aware of any emergency fiber work. The NOC said that a tech was dispatched and he was hoping they would be able to fix it in the next few hours. Frank

I would like to strongly encourage MICE's participation, but I believe we have work to do to make it happen. https://www.internetsociety.org/blog/2018/04/introducing-a-new-manrs-ixp-pr… https://www.manrs.org/participants/ixp/ Thanks -- =============================================== David Farmer Email:farmer@umn.edu Networking & Telecommunication Services Office of Information Technology University of Minnesota 2218 University Ave SE Phone: 612-626-0815 Minneapolis, MN 55414-3029 Cell: 612-812-9952 ===============================================

Re: CNS Satellite Cutover
by Dean Bahls April 12, 2018

April 12, 2018

Good morning! The new CNS satellite has been cut into service. Traffic seems to be flowing normally. Holler if you see potential issues that we might have caused. Thanks, Dean From: Dean Bahls <dean.bahls(a)cooperative-networks.com> Sent: Wednesday, April 11, 2018 6:39 AM To: 'MICE Discuss' <MICE-DISCUSS(a)LISTS.IPHOUSE.NET> Subject: CNS Satellite Cutover Good morning MICEers! Sorry for the short notice, but CNS will be cutting to a new switch tomorrow morning (4/12/18) at around 10:00am. Yes, that seems like an odd time to do maintenance, but with all of the Netflix caching going on between 2:00am and 9:00am, this is about the slowest part of the day anymore. If you have questions, please feel free to contact me. Thank you!

Old MICE Traffic Levels
by Jeremy Lumby April 10, 2018

April 10, 2018

I took the MICE display that was next to the Cologix Suite 200 entry in order to update it. When I opened it I was surprised that on the back was a previous version from when the MICE traffic was under 10G. It was a great surprise, so I attached a picture for your appreciation of how far we have come. I plan on keeping all previous versions on the back of the frame to preserve some history.

MN VoIP Extension switch link upgrade
by Jeremy Lumby April 7, 2018

April 7, 2018

On Saturday 4/7/2018 at approx 2pm MN VoIP will be cutting the link to their MICE extension switch from 10G to 40G. BGP will be blocked ahead of time to allow traffic to gracefully reroute. The estimated downtime will be less than 5 minutes.

MICE Google Global cache issues?
by Colin Murphy April 6, 2018

April 6, 2018

Hi, Since Monday we've been having issues with mobile devices accessing YouTube and Google Play store via IPv6. Our symptoms with YouTube app is mostly with Apple IOS devices. When a user loads a video, the ads will play fine and then the video will start and play for 5 seconds and stop. Browsing youtube via a web browser on the IOS devices seems fine. With Android devices, users can't download apps from the play store. Is anyone else experiencing these issues with their peering with the Google Global Cache at MICE? Thanks, Colin Murphy Sr. Network Engineer Office of Information Technology University of Minnesota Northern Lights Gigapop Desk: 612-626-0870

Broadcast Traffic
by Jeremy Lumby April 3, 2018

April 3, 2018

I have been watching the broadcast traffic on MICE steadily increase. We are now at the point where our broadcast traffic is 10X that of many exchanges that are larger than us. I would encourage the membership to look over the configuration of their peering routers to make sure that they are configured in a way that they are not generating excessive broadcast traffic. In the past on the list we have referenced the Amsterdam Internet Exchange configuration guidelines. I feel that the router specific configuration hints are a great starting point to be sure that your router is configured properly. https://ams-ix.net/technical/specifications-descriptions/config-guide Jeremy Lumby Minnesota VoIP 9217 17th Ave S Suite 216 Bloomington, MN 55425 Main: 612-355-7740 x211 Direct: 612-392-6814 EFax: 952-873-7425 jlumby(a)mnvoip.com

MICE UG 27 Meeting
by Richard Laager March 26, 2018

March 26, 2018

The MICE UG 27 meeting will be held Monday (not our typical Wednesday), March 26, 3:00 pm, at the 511 Building Cafeteria, 11th Avenue South, Minneapolis, MN. While this meeting is timed to coincide with MTA, we are meeting at the 511 Building as usual, not at the MTA hotel location. The agenda and draft UG 26 minutes are attached. I believe the remote conferencing will be the same as before: 952-562-5400 passcode MICE (6423). -- Richard
