You have a problem that you can describe on a whiteboard, but you can't get an off-the-shelf solution for, and you want to solve it by sitting down and writing an ordinary program in an ordinary high level programming language. So that is what you do. It's not necessarily *easy* but it is straight forwardly similar to the way people write other programs in languages like perl/python/ruby/javascript/etc.

I'm sorry you've had a negative experience and we should do better. Let's start by fixing your issues. If you are interested in chasing this down to resolution I'm 100% dedicated to getting this solved for you off list. If you're willing I'll even report back with what we found and how we fixed it. - Pete, Cumulus TME On Fri, Jun 15, 2018, 5:49 PM wrote: > On 06/15/2018 10:17 PM, John Fraizer wrote: > >- What specific issues are you having with BGP running under Cumulus > >Linux. > - bgpd crashes > - bgpd loading as hell after some time (can be fixed by restarting the > process ..) > - cumulus by itself (switchd & portwd) loads as hell as well, all the > time, the hardware is under pressure all the time (which is an issue for > CPU-based stuff : monitoring, sflow etc) > > >- What hardware are you running Cumulus Linux on? > 5712-54X-O-AC-F from edgecore > (https://www.edge-core.com/productsInfo.php?cls=&cls2=&cls3=44&id=15), > which has specific issues by itself as well :/ > > >- What version of Cumulus Linux? > The last one, 3.5.2 > > > > > > > > -- > > John Fraizer > > LinkedIn profile: http://www.linkedin.com/in/johnfraizer/ > > > > > > > > On Thu, Jun 14, 2018 at 5:28 PM, wrote: > > > >> Bof > >> > >> I currently use cumulus's software, I will then report my experience: > >> not production ready > >> > >> You have a lot of features, with a fast development, but .. > >> I expect my network to be a rock solid part of my infrastructure, > >> especially when I am using the classic part, not the fancy ones > >> > >> When I have huge stability issue with something like bgp, what can I say > >> but "get away from those software, it is not production-ready yet" ? > >> > >> > >> > >> > > > >
Re: fd.io vs cumulus vs snabb vs OVS vs OpenNSL
Hi, Well, 3.5.2 isn't exactly latest, there is 3.5.3, 3.6.0 and 3.6.1 also. But I guess switchd running cpu somewhat hot is normal (40% load in empty switch or so) as it is polling all the stuff from asic etc. I do agree that cpus on many edgecores & dells and similar are somewhat under powered, but haven't encountered similar problems with that (yet) myself. Would be also very interested to hear more specifics. , Henri On Fri, 2018-06-15 at 23:47 +0200, na...@jack.fr.eu.org wrote: > On 06/15/2018 10:17 PM, John Fraizer wrote: > >- What specific issues are you having with BGP running under Cumulus > >Linux. > > - bgpd crashes > - bgpd loading as hell after some time (can be fixed by restarting the > process ..) > - cumulus by itself (switchd & portwd) loads as hell as well, all the > time, the hardware is under pressure all the time (which is an issue for > CPU-based stuff : monitoring, sflow etc) > > >- What hardware are you running Cumulus Linux on? > > 5712-54X-O-AC-F from edgecore > (https://www.edge-core.com/productsInfo.php?cls=&cls2=&cls3=44&id=15), > which has specific issues by itself as well :/ > > >- What version of Cumulus Linux? > > The last one, 3.5.2 > > > > > > > > -- > > John Fraizer > > LinkedIn profile: http://www.linkedin.com/in/johnfraizer/ > > > > > > > > On Thu, Jun 14, 2018 at 5:28 PM, wrote: > > > > > Bof > > > > > > I currently use cumulus's software, I will then report my experience: > > > not production ready > > > > > > You have a lot of features, with a fast development, but .. > > > I expect my network to be a rock solid part of my infrastructure, > > > especially when I am using the classic part, not the fancy ones > > > > > > When I have huge stability issue with something like bgp, what can I say > > > but "get away from those software, it is not production-ready yet" ? > > > > > > > > > > > > > >
re: fd.io vs cumulus vs snabb vs OVS vs OpenNSL
Hi, Gleaned this thread on nanog mailer archive [1] mentioning fd.io :) Not a "thought leader", but I thought I respond with some fd.io data points, hopefully relevant to the thread’s subject. Note that most of them focus on data plane functionality, performance and technology level comparison: - IPv4 routing (large FIB) at Terabit speed, a video clip (low-budget) showing what difference modern Xeon processors (Skylake) can make to SW data plane if coupled with something super-fast, produced by LF FD.io project for Xeon Skylake launch on 11th July 2017 (a year ago). [2] - SW data plane benchmarking, technical paper [3][4]. - Test and performance report for last fd.io release [5]. - Continuous trending of fd.io vpp master branch [6]. And although network control plane is not covered (e.g. BGP), many data plane hooks required are there incl. large FIBs, VRFs, hierarchical FIB for IP fast convergence, multicast, etc. HTH -Maciek [1] https://mailman.nanog.org/pipermail/nanog/2018-June/095897.html [2] "FD.io: A Universal Terabit Network Dataplane", https://www.youtube.com/watch?v=aLJ0XLeV3V4.

Re: fd.io vs cumulus vs snabb vs OVS vs OpenNSL
I would also be very interested in what specific issues you are having... - What specific issues are you having with BGP running under Cumulus Linux. - What hardware are you running Cumulus Linux on? - What version of Cumulus Linux? -- John Fraizer LinkedIn profile: http://www.linkedin.com/in/johnfraizer/ On Thu, Jun 14, 2018 at 5:28 PM, wrote: > Bof > > I currently use cumulus's software, I will then report my experience: > not production ready > > You have a lot of features, with a fast development, but .. > I expect my network to be a rock solid part of my infrastructure, > especially when I am using the classic part, not the fancy ones > > When I have huge stability issue with something like bgp, what can I say > but "get away from those software, it is not production-ready yet" ? > > > >

I'd be curious about specifics. We've got some Cumulus with BGP and it hasn't given us any issues. Granted, it's very vanilla with a couple of SVIs per switch and just basic IPv4 unicast and it's just a management network, but it hasn't caused us any issues that I'm aware of. -- Hugo Slabbert | email, xmpp/jabber: h...@slabnet.com pgp key: B178313E | also on Signal signature.asc Description: Digital signature
