Re: Traffic Drop

by Ben Wiechman

We had some unusual traffic patterns this afternoon too. A huge surge, with a massive dip early evening and now traffic appears to be flowing at fairly typical levels. Weird.

Traffic Drop

by Jeremy Lumby

I noticed a huge drop in MICE traffic, and was wondering if there was a fiber cut somewhere, or some other underlying reason for the drop off.

Were there any additional details regarding these issues? Do these issues begin to affect all traffic (some kind of queue exhaustion) or are they typically only experienced when passing traffic from the high bandwidth 100G links to the "low" bandwidth 1G links, or vice versa?

I think Jay's point was that our smaller members have 1G interfaces and we're talking about the next generation of switch having 100G interfaces. I bet many of us had similar queue experiences with older platforms during our early 10G migrations, and larger exchanges that are at the 100G level may be seeing queue drops in even modern hardware. So we'll want to interrogate potential switch vendors and be mindful of the issue. Sorry if that wasn't clear.

A Brocade ICX7750 with a similar port density is also potentially a similar cost. Havent compared feature set between those. The recent Broadcom announcement muddies that water a bit as well.
