AT&T Austin multiple 10Gs hard down, anyone seeing issues as well?
by Nick Crocker 17 Jun '16

17 Jun '16

Looking at some sites and hearing chatter of a pretty wide scale AT&T outage in the Austin and surrounding areas. I have two 10Gs one fed out of Pflugerville, TX and one out of Austin, TX with PE's in Austin, TX and San Antonio, TX. Both dropped at the same time and are on diverse fiber routes and entrance facilities with power and equipment verified. Regards, Nick

1GE L3 aggregation
by Saku Ytti 17 Jun '16

17 Jun '16

Hey, I've been bit poking around trying to find reasonable option for 1GE L3 full BGP table aggregator. It seems vendors are mostly pushing Satellite/Fusion for this application. I don't really like the added complexity and tight coupling Satellite/Fusion forces me. I'd prefer standards based routing redundancy to reduce impact of defects. ASR9001 and MX104 are not an options, due to control-plane scale. New boxes in vendor pipeline are completely ignoring 1GE. I've casually talked with other people, and it seems I'm not really alone here. My dream box would be 96xSFP + 2xQSFP28, with pretty much full edge features (BGP, LDP, ISIS, +1M FIB, +5M RIB, per-interface VLANs, ipfix or sflow, at least per-port QoS with shaper, martini pseudowires). With tinfoil hat tightly fit on my head, I wonder why vendors are ignoring 1GE? Are business cases entirely driven now by Amazon, Google, Facebook and the likes? Are SP volumes so insignificant in comparison it does not make sense to produce boxes for them? Heck even 10GE is starting to become problematic, if your application is anything else than DC, because you can't choose arbitrary optics. -- ++ytti

IXP economics Was: Re: NANOG67 - Tipping point of community and sponsor bashing?
by Martin Hannigan 16 Jun '16

16 Jun '16

Well. Its complicated. I think this is far more political than about COGS. But hey. Why not? I agree with Dave. Shocking. I know. At least the context. He's right. Thanks for reminding us. We know these things. We'll have to see how IXP communities react now. Perhaps espresso service will be defined as good outreach? If it is, thats certainly up to them. Btw, have you thanked your local US branded euro IXP? They created market pressures that saved many of us a Brinks truck full of cash by increasing competitiveness. A lot of us owe them thanks and support for doing good. If you do, grab Job, John, Henk, Pauline, Arnold or Andreas and give them a big COGS crushing hug. Go easy on Pauline, less crush please.

a lot of PR fluff, but this may be of interest: http://www.wired.com/2016/06/barefoot-networks-new-chips-will-transform-tec… https://barefootnetworks.com/media/white_papers/Barefoot-Worlds-Fastest-Mos… Based on their investors, could have interesting results for much lower cost 100GbE whitebox switches.

Strange Problem with 16 byte packets
by Glen Kent 16 Jun '16

16 Jun '16

Hi, I am using a proprietary protocol and sending a bunch of bytes to a Draytek router at an enterprise site. When i send the data in TCP batches of 1 MB i see no problem. However, when i first send 16 bytes followed by 1 MB of data, and then repeat this till the entire data has beeen sent out. During this process I see that my TCP session times out. Unable to understand why this could be happening? How can sending 16 bytes of data followed by 1MB of data affect the transfer. Thanks !

Hello, a little question :) For mobile operators using v6 on their networks, how do you manage link-local communication between mobile phones ? While I understand it's layer 2 related, am i able for example to make ping sweep and be able to communicate directly with other phone (customer) ? -- Willy Manga (from where I stand mobile operators do not use yet v6 :-\ ) freenode: ongolaBoy Ubuntu Cameroonian Loco Team https://launchpad.net/~manga-willy

Comcast (DOCSIS) issues in Boston?
by Spencer Ryan 15 Jun '16

15 Jun '16

Anyone seeing any issues with routing into Boston? We have a DOCSIS link that seems unroutable past 350 E Cermak in Chicago, traceroutes from two carries here in Michigan stop there. We have a fiber (EDI/BGP) with them at the same location and I'm not seeing any issues on that link. The site itself can ping it's default gateway but can't get anywhere else. *Spencer Ryan* | Senior Systems Administrator | sryan(a)arbor.net *Arbor Networks* +1.734.794.5033 (d) | +1.734.846.2053 (m) www.arbornetworks.com
