I’ve talked a little on this site before about what we’re trying to achieve with OpenConfig. However, one of the observations that it’s easy to make is that YANG models alone don’t really achieve anything in terms of making the network more programmable. To make the network more programmable, we need to have tooling that helps us create instances of those modules, manipulate them, and then serialise the into a format that can be used to transmit data that conforms to the model to a device.

On Friday, I presented at the Netnod meeting in Stockholm, Sweden - again about BGP error handling - this time presenting a bit of an update as to why this continues to be a problem for the Internet (and private BGP deployments) - and why this work is still really relevant. In addition, I tried to give an overview of what the solution space looks like. I’m not sure whether there’s video, but as usual, the slides are linked below!

As I presented at UKNOF 18, I have now written an Internet-Draft to address the requirements of Network Operators for how BGP should handle errors in UPDATE messages. The draft can be found on the IETF site, and I'm currently seeking opinions as to whether this reflects the an operational consensus! If you're an Operator (DFZ, MSE or otherwise), it would be great to hear from you! I'll be presenting the draft at NANOG 51 in Miami on Tuesday - if you're there, feel free to ping me!

I spoke at LINX71 about the testing that we (C&W) have been doing in the lab with 100GigE - we got a pre-production card and hence had a look at the technology for real. Thanks to LINX, the presentation video can be seen by clicking on the image below. Once again, however, whatever LINX use as a presentation laptop didn't render my slides properly - even though I'd submitted PDF too!

Tom Bird of PortFast and Brandon Butterworth of Bogons do a great job of webcasting, and recording UKNOF video. Thanks to them, the video of the presentation I gave at UKNOF16 can be watched here. Or you can download it by clicking the image below! As always, thoughts/comments/corrections most welcome! This is also probably a good time to mention that my new work mail address is rob.shakir (at) cw.com

For information, and because it means that I have revoked a bunch of UIDs from my GPG Key I am no longer working at AS5413 (Vialtus, Daisy, GX Networks etc.) as of June 18th, 2010. It's been a good two years, but the company direction no longer co-incides with the direction in which I would like to go. I've enjoyed the projects I've worked on, been in contact with a lot of great people, and learnt a lot!

So, if we take a moment to look at the following responses to questions that the leaders of the three parties involved in the “Digital Debate” on YouTube gave, concerning the Digital Economy Bill: Sure, we get some tired old rhetoric, as expected. However, the key point here is that both Labour and the Conservatives appear to believe that they’ve done the right thing with this bill.

I’ve had a couple of mails relating to this PSN, which again references the research that Andy Davidson, Jonathan Oddy and I did last year. It seems that some of the sources of the initial mailing list posts we made are gone (particularly the merit.edu one that is referenced from both Juniper’s site and most other places). For that reason, I’ve included both the mails that we sent to NANOG/C-NSP/J-NSP last year here.

A quick personal post to break the silence here! I’m currently very interested in hearing about any UK or EU-based network engineering or architecture opportunities that are out there, especially in SP networks that run MPLS with TE. If anyone has some such opportunity, or knows of something that they think might suit me – please drop me a mail to email@example.com for a copy of my CV. An outline of my CV is available on LinkedIn.

Further to my previous post - I presented this issue at LINX65 - video and slides can be found below. Video Fixed Slides - LINX’s PowerPoint install seems to have corrupted my slides on the day. Comments and feedback are most welcome.
