beating bufferbloat with better hardware
by Dave Taht 09 Apr '15

09 Apr '15

When I was at the nznog conference there was a lot of despair about a lot of aspects of the fiber deployment, and the quality of the home gateways, and what seemed to be promising plans to try to get openwrt with fq_codel running on nzwrt... did you all despair completely? I talked about all the great things we could do to improve our devices with openwrt, and and beat bufferbloat in particular with fq_codel in my talk... and since then I have worked to get fq_codel in more and more OSes and hardware. UBNT has added configuration tools for it in their upcoming edgerouter 1.7 release. VyOS just added it. It is in click. It is in fedora 22. It is spreading (And of course, already in all modern linuxes, openwrt, dd-wrt, ipfire, shorewall, etc). There was no sign of a pulse at tilera or mikrotik, but I will keep trying. Still... to one day get hardware that has low latency and good queue management at gigE speeds or higher requires better hardware offloading techniques than the bulk notions like GRO and TSO that exist today. And it has long been obvious that the rate limiting + fq_codel techniques we use successfully at sub 200mbit speeds do not scale higher. So the algorithms need to move into hardware, also. *******so... a brief commercial interruption***** I think the open source design method has worked spectacularly for software, and I think the same methods can work for hardware if only we can pull together larger communities to do the work, worldwide. There are only 24 hours left on this kickstarter - we CAN *start* to take back the edge of the internet - if we can only find another 5k of funding. https://www.kickstarter.com/projects/onetswitch/onetswitch-open-source-hard… This FPGA board´s pcie interface and switch design - and the split memory interfaces between the programmable logic and the onboard dual A9 core - and reducing the cost from 7000 to 700 bucks - are the important parts to why the community needs this board - in my case - so that more of htb + fq_codel can move into hardware that anyone can build and use - in other cases? who knows what could be done with it!? One day, we could move the logic into asics, and finally have open source, blob-free hardware to work with for any network purpose. There are people on these lists with money, and there are those with talent and time, and it would be great if more of those people could line up with each other. I put in all I could spare (8500 dollars) into this kickstarter. I have one of their high end boards, already. It´s great. There is a get one give one program that I asked meshsr to put in to try and enable that event. If there is anyone here that would like to help hack together the next generation of edge network hardware, after this kickstarter completes, let me know. I return you now to your normal despair about vendors not listening, and crappy OSes you can´t otherwise fix. -- Dave Täht We CAN make better hardware, ourselves, beat bufferbloat, and take back control of the edge of the internet! If we work together, on making it: https://www.kickstarter.com/projects/onetswitch/onetswitch-open-source-hard…

SNMP for Mako / SecureME
by Tom Henderson 09 Apr '15

09 Apr '15

Wondering if anyone here knows if Mako routers (Spark's SecureME offering) can be monitored with SNMP? We use observium to monitor our servers and existing Cisco gear, but so far it looks like I can only monitor these from the SecureME web portal.

Call for presentations for AusNOG 2015
by Jamie Baddeley 07 Apr '15

07 Apr '15

A Call for Presentations from our mates across the ditch. Cue comments about Cricket, Currency Parity, Phar Lap, Pavlovas, Russell Crowe, Crowded House, Underarm bowling, etc etc.. Cheers Jamie ---------- Forwarded message ---------- From: Terry Manderson <terry(a)terrym.net> Date: 1 April 2015 at 05:39 Subject: [AusNOG] Call for presentations for AusNOG 2015 To: ausnog <ausnog(a)lists.ausnog.net> Call for presentations for AusNOG 2015 =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Langham Hotel Melbourne 27 & 28 August 2015 Topics =-=-=- Internet operations can be a broad topic and the programme committee will be short-listing presentations in the following focus areas: * Improving the redundancy/resiliency/sustainability of your network * Making leaps in service or network availability * Taking the network operations BCP to the next level * Using 'offline' communications tools to keep the network working * How technology is changing network architectures * Evolution in network architectures and scaling issues * Analysis of relevant major operational events of the year Additional topics that are of interest to the network operator community are also welcome at AusNOG 2015. Naturally, presentations of a marketing nature are not welcome at this technical event. Notes to presenters =-=-=-=-=-=-=-=-=-= Preference will be given to presentations that result in actual operational outcomes. Session speakers should be prepared to present for 30 minutes. Keynote speakers will be expected to present for 45 minutes to 1 hour. Short presentations of strong operational content are also acceptable. Once the final slides are submitted, changes will only be permitted where the presentation requires the most up to date information or data. By submitting a presentation for consideration in the AusNOG 2015 programme, and if selected the presenter will allow AusNOG to: * Take photographs of the presentation and presenter * Record and rebroadcast video and audio of the presentation and presenter * Redistribute the presentation slides, audio, video, and photographs electronically, on the AusNOG website, or otherwise but leaving all intellectual property in the hands of presenter or rightful property holder[1]. Deadlines =-=-=-=-= 04 June: Submission of presentation title, presentation description (300 words), and presenter biography (200-400 words) 02 July: Presenters notified of their acceptance status as an AusNOG 2015 presentation. 20 August: Submission of final presentation slides as Portable Document Format (pdf), PowerPoint, or Keynote. Provision of a recent digital photograph (<500k) of the presenter. All submissions must be sent by email to organisers AT ausnog DOT net. A separate call for lightning talks will be made closer to the AusNOG 2015 event. As in previous years you must be registered to attend AusNOG 2015 in order to be considered for a lightning talk. [1]: AusNOG accepts that some speakers are unable to allow us to archive their presentation due to company or corporate policy, and if the situation arises AusNOG will delete all copies in its possession after the presentation. Lightning Talks =-=-=-=-=-=-=-=-= Have something awesome or cool to share that isn't a full presentation? New to presenting, and still want give back to the community? Why not consider a lightning talk? Lightning talks are short (max 10 minute) presentations on topical material. There is no requirement for any slides! A call for lighting talks will be made nearer to AusNOG 2015. Cheers Terry (For the AusNOG Board)
