A question that came up at an event I was at yesterday: How will the time between the first (commercial) deployment of a telephony service, and a regulated universal service obligation for telephony compare to that of the time between the first (commercial) Internet services being deployed and a USO for IP connectivity (e.g., Broadband)? Based on this, is the cycle time of the telephony regulatory bodies, and mechanisms through which changes are implemented within these bodies suitable for Internet services?

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!

At one of the Ericsson R&D days, Professor Scott Shenker - who's an academic at the University of California in Berkeley, presented on a concept that he calls the "software defined network'. Now, if you haven't seen the presentation - it's definitely worth watching (it's on YouTube, here), and provides quite an engaging look at the problem of network scaling from the perspective of academia, and especially in terms of a comparison to the more rigorous disciplines of computer science, like OS design.

It's been quite a while since I updated this blog, very lax of me, sorry! The lack of updates appears more indicative of how busy I appear to have been since presenting the error handling draft work at NANOG (which looks to be the last post!). Since January, I've presented at the IETF in Prague, and then again in Qu�bec City - particularly on a number of aspects of the work that I've been documenting here for some time!

The video from the presentation I gave a NANOG, LINX and UKNOF has now been posted. You can find the video at the following URL - NANOG 51: BGP Error Handling or by clicking on the image below. The full slide deck is also on this site - here.

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!

I took some photos of the Ghent 6 day on the Grupetto trip out there. The full gallery is here, but some selected highlights are below:

With IETF 79 happening last week - I think one of the great things that's coming out of the IDR work leading up to the meeting has been that quite a few drafts have been written around the requirements that exist in BGP for better error handling. I've been vocal about this before, of course, so it's not that surprising that I'm (yet again) banging the drum for this cause, however, we are getting somewhere finally.

Herne Hill is looking for support, it’s both historic, and a fantastic facility in London. It’d be great to see more people supporting this! Here’s the campaign page.
