I've been a member of the various EDUCAUSE lists/groups for longer than I remember. What I always appreciated was the ability for EDU and non-EDU folks to openly share whatever we could with a few reasonable restrictions. I certainly learned a giant pile of stuff from everyone here, and I have been struck ...

As can be imagined, there were no firm disclosures made to talk about the futures of any specific products/services, since the acquisition is still moving toward completion in late 2024 or early 2025. The general statements that I got from sessions that I attended were nothing surprising at this point ...

We've been using public CA for EAP-PEAP since we first started doing 802.1X authentication back in the 2000's. Obviously as time has gone on, that has proven to be suboptimal for a number of reasons, including the need to rotate the certificate at ever-decreasing intervals, not to mention the security ...

I would think the rate would be heavily market-dependent. I can't share our data publicly, but I can probably get you a rough neighborhood with respect to what we're charging in the Chicagoland area.

There are OS-level options for this as well, but that assumes that the notifications are coming through the OS notifications pathways (which MS Teams only started doing recently). On macOS, for example, if you go to System Settings->Notifications, there's an option to "Allow notifications when mirroring ...

We had both our branded "Northwestern" SSID and eduroam running in parallel for years. Back in 2020-2021 or so we started a communication campaign to get people to move off of the branded one. With the pandemic, we delayed our deactivation of the branded SSID by a few months, but it all went fairly well. ...

Here are the public pages on NU's high performance computing clusters that we run centrally. https://www.it.northwestern.edu/departments/it-services-support/research/computing/quest/ If you want to talk in a little more detail, drop me a line. If you want to talk in a lot more detail, I'll have ...

Heheh.....more fun fuzzy memories on this one. I remember way back when we first made the switch to OSPF from RIP, and we first did many of the bells and whistles in terms of breaking up the campus by area (basically each distribution routing site was its own area), route aggregation whenever possible ...

Argh. Was trying to respond to Chuck's comment about ATM networking, but I guess selective email quoting still doesn't work on this system. :) To contribute something more substantive, we also have had a mandate for the last few decades that said that if you're in a university owned building, you ...

That is one of the best ways of describing those times I've heard in a while. Oh the memories..... :)

We gave up on traffic shaping years ago when PacketShaper development stalled and wasn't able to keep up with the amount of bandwidth we needed, plus the costs of bandwidth went down enough that it wasn't worth it for us to continue to pay for an appliance that was for us at least just going to make ...

We've asked for a high level briefing on this from our carrier as well just to understand how these services work. A lot of the simpler more clear cut rules with respect to caller ID have definitely been thrown out the window in recent years. :) -- Julian Y. Koh Director, Telecommunications ...

My Sonoma machine as well as a coworker's were able to connect to eduroam on our campus just fine. At the risk of going too much off on a tangent, I've got a sample size of n=1 so far with my iPhone 11 and iOS 17 (and 17.0.1 and 17.0.2). The day after upgrading, I came to campus, and it wouldn't join ...

Sounds interesting, Arthur. Just curious - Is there an option to make the network path be primary and the cellular dialup be secondary? -- Julian Y. Koh Director, Telecommunications and Network Services Northwestern Information Technology 2020 Ridge Avenue #331 Evanston, IL 60208 ...

We connect those to analog gateways that register to our Cisco UC Manager infrastructure. Cellular options are being explored for our alarm panels, but we have not really been looking too hard for an option for our Ramtel phones. We also have a fair installation of Valcom IP-based emergency phones that ...

We have been using Xfinity OnCampus streaming for a number of years now. Prior to that we were doing Video Furnace/Haivision multicast streaming going back to 2001. And for many years before that our president was telling students that they were there to learn, not watch TV. :) :) -- Julian ...

We are also considering such a move. Vantage just finished helping us do an analysis of things over the past months; here's a link to one of the threads that Jon Young had related to a survey that was circulated along with the results: https://connect.educause.edu/discussion/certificate-based-aut ...
