Some reflections on the development of Software-Defined Networking, and how it has impacted the ongoing re-imagining of network devices that OpenConfig, and associated projects has driven.

We spent a few days in the High Sierra, off the grid, hiking the Big Pine Lakes trails.

Marcus Hines and I spoke at NANOG86 on some of the work that we’ve been doing related to emulating network topologies in Kubernetes, and how this relates to improving network testability.

A while ago, I removed my instagram account.

I originally posted this as a comment on hackernews in response to a post about this article in The Atlantic.

For more regular updates, you can generally find me on instagram, or Héloïse on instagram.

Inspired by Becca on the swing at Bernal Heights.

The concept of having no central entity control currency seems attractive to a lot of people.

Anees Shaikh and I put together some thoughts that we shared with rtgwg at IETF 98 in Chicago.

Welcome to a new rob.sh, apologies for the outage.

Anees Shaikh and I presented at future:net talking about automation work that we’ve been doing in OpenConfig, and I shared some of the NMS implementation I’ve been working on recently.

At IETF96 in Berlin, the chairs of the NETMOD working group, and Operations Area Director (Benoit Claise) published a statement to say “Models need not, and SHOULD NOT, be structured to include nodes/leaves to indicate applied configuration”.

Mark Townsley and Jean-Louis Rougier again invited me to come and lecture at École Polytechnique this year.

I’ve talked a little on this site before about what we’re trying to achieve with OpenConfig.

I noted that at NANOG64 this week in San Francisco, there are talks (both from Juniper) about both SPRING/Segment Routing and RSVP-TE.

Both the Hawaii IETF meeting (IETF91) and the subsequent meeting we had a few weeks ago in Dallas were somewhat YANG-heavy.

After my presentation at UKNOF on SR, Mark Townsley asked me whether I'd be interested in presenting to his class at the Ecole Polytechnique in Paris, around the thinking (from an ops perspective) of delivering the 5218 concept of "net positive value" thr…

I recently gave a talk at UKNOF relating to Segment Routing/SPRING and the operational challenges that we are trying to resolve through it.

Almost two years ago I wrote a post on this site entitled Some Initial Thoughts on the SDN.

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 (commercia…

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 sti…

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'.

It's been quite a while since I updated this blog, very lax of me, sorry!

The video from the presentation I gave a NANOG, LINX and UKNOF has now been posted.

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.

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.

I took some photos of the Ghent 6 day on the Grupetto trip out there.

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.

Herne Hill is looking for support, it's both historic, and a fantastic facility in London.

Tom Bird of PortFast and Brandon Butterworth of Bogons do a great job of webcasting, and recording UKNOF video.
