RE: Soliciting your opinions on Internet routing: A survey on BGP convergence

Hi Baldur, Have you tried graceful shutdown? You need redundant links, but not to the same transit. https://tools.ietf.org/html/draft-ietf-grow-bgp-gshut-06 This draft is expired, but it is actually implemented by several vendors. I implemented this. http://www.slideshare.net/bduvivie/bgp-graceful-shutdown-ios-xr I added an option to configure AS-path prepends in case the gshut community was not supported by peers. Thanks, Jakob. > Date: Tue, 10 Jan 2017 03:51:04 +0100 > From: Baldur Norddahl <baldur.norddahl(a)gmail.com> > > Hello > > I find that the type of outage that affects our network the most is > neither of the two options you describe.

Some standard of showing "this is how my network works"?
by Mike Lund 10 Jan '17

10 Jan '17

Hey, sorry for bad title. I am wondering if there is some standard that is gaining traction which gives actual useful information regarding an IP. My biggest example is HE's rwhois referral, giving information about the given IPv6 IP -- if it's a /64, /48, etc. Such information that helps abuse admins make more-accurate policy decisions. This is just an example, there could be other useful information as well. Is this such a thing anywhere? Or is it like most networking things, where only the smaller companies do anything useful like this? Thanks for your time!

Soliciting your opinions on Internet routing: A survey on BGP convergence
by Laurent Vanbever 10 Jan '17

10 Jan '17

Hi NANOG, We often read that the Internet (i.e. BGP) is "slow to converge". But how slow is it really? Do you care anyway? And can we (researchers) do anything about it? Please help us out to find out by answering our short anonymous survey (<10 minutes). Survey URL: https://goo.gl/forms/JZd2CK0EFpCk0c272 <https://goo.gl/forms/WW7KX5kT45m6UUM82> ** Background: While existing fast-reroute mechanisms enable sub-second convergence upon local outages (planned or not), they do not apply to remote outages happening further away from your AS as their detection and protection mechanisms only work locally. Remote outages therefore mandate a "BGP-only" convergence which tends to be slow, as long streams of BGP UPDATEs (containing up to 100,000s of them) must be propagated router-by-router. Our initial measurements indicate that it can take state-of-the-art BGP routers dozens of seconds to process and propagate these large streams of BGP UPDATEs. During this time, traffic for important destinations can be lost. ** This survey: This survey aims at evaluating the impact of slow BGP convergence on operational practices. We expect the findings to increase the understanding of the perceived BGP convergence in the Internet, which could then help researchers to design better fast-reroute mechanisms. We expect the questionnaire to be filled out by network operators whose job relates to BGP operations. It has a total of 17 questions and should take less 10 minutes to answer. The survey and the collected data are anonymous (so please do *not* include information that may help to identify you or your organization). All questions are optional, so if you don't like a question or don't know the answer, please skip it. A summary of the aggregate results will be published as a part of a scientific article later this year. Thank you so much in advance, and we look forward to read your responses! Laurent Vanbever (ETH Zürich, Switzerland) PS: It goes without saying that we would be also extremely grateful if you could forward this email to any operator you might know who may not read NANOG.

premiumcolo.net IP address rental
by Joel M Snyder 09 Jan '17

09 Jan '17

Folks: I've been getting mail from "premiumcolo.net" offering to rent unused IPv4/IPv6 space. Their web site is a farce of random phrases, grammatical errors, misspellings, and randomly inserted words, and won't even render in Firefox. That being said, I'm curious as to whether anyone has had any experience with them or knows the back story. Also, is there some reason that there is no official searchable archive of the nanog mailing list? (or dependable unofficial one...)? Best in the new year to you all, jms -- Joel M Snyder, 1404 East Lind Road, Tucson, AZ, 85719 Senior Partner, Opus One Phone: +1 520 324 0494 jms(a)Opus1.COM http://www.opus1.com/jms

Bonded VDSL2 / ADSL2+ Modems with 4 or more lines bonded
by Colton Conor 09 Jan '17

09 Jan '17

What options are out there to bond 4 or more DSL lines together? I know Positron has a 4 and 8 pair VDSL2 modem http://www.positronaccess.com/AK626LC.php Adtran has a 8 port VDSL2 modem https://portal.adtran.com/web/page/portal/Adtran/product/1172868F1/470 and an Adtran 12 port ADSL2+ modem https://portal.adtran.com/web/page/portal/Adtran/product/1172850G1/470 Actelis has a 8 pair VDS2 Modem: http://actelis.com/actelis-products/ethernet-access-devices/ml700/ Is there anyone else out there? The problem with all these solutions is they each cost over $1000, which is a lot considering 2 port bonded VDSL2 modems are in the $75-150 range. I know demand for these products is low, but still hoping there is an OEM version.

PSN download speeds
by MKS 09 Jan '17

09 Jan '17

Hello I have been testing the download speed from PS4 store, downloading game demos etc. So far I have seen content coming from cloudfront.net, llnw.net and level3 Does someone know if the PlayStation/Sony has contracts with all these CDNs (and perhaps more) or if it's the publishers that choose/handle the distribution of files? So far i'm only getting download speeds of 10-20mbps even though i'm on a 100mbps connection, so downloading a 8Gbps file take too long. Are the PS4 downloads generally rate-limited or am I just unlucky? Regards MKS
