Speed of Internet Innovation.
imported Blitherings · Tech · ThoughtsA 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?
Some Initial Thoughts on the Software-Defined Network (SDN).
imported Tech · MPLS · MPLS_TE · IETF · SDN · ThoughtsAt 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.
Progress with Error Handling for BGP
imported Tech · BGP · IETF · PresentationsIt'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!
NANOG 51 Presentation

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.
BGP Error Handling - Developing an Operator-Led Approach in the IETF
imported Tech · ISP · BGP · IETF · Presentations · UKNOFAs 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!
LINX71 - 100GE in the Lab
imported Tech · Work · ISP · PresentationsI 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!
BGP Error Handling and Enhancements Post IETF-79
imported Tech · Work · BGP · IETFWith 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.
Cycling Video
imported Tech · CyclingChecking out a few videos that people have linked me to recently I thought that this piece was amazing - really great speed. It also looks like the 5D and 7D are really quite awesome at doing 60fps HD! The video presentation over at vimeo is really cool too! PUSH PULL from Landis Fields on Vimeo.
Digital Economy Bill YouTube Questions
imported Tech · ISP · UKSo, 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.
UKNOF 16: Enhancing BGP
imported Tech · Work · BGP · IETF · UKNOF · PresentationsAfter a late programme committee request, I presented on “Enhancing BGP” at UKNOF 16. The presentation was intended to be an update on the current drafts in the IDR working group, and give some encouragement to operators to get involved, and contribute. I’ll put the video up when the Tom at PortFast and Brandon of Bogons have done their excellent job on it. For the meantime, the slides are linked below.
