Feedback Requested: Routing Resilience Manifesto
by Andrei Robachevsky 02 Jul '14

02 Jul '14

Colleagues, A small group of network operators has been working on defining a minimal, but feasible package of recommended measures that, if deployed on a wide scale, could result in visible improvements to the security and resilience of the global routing system. Many operators are ahead of the curve and already implement much more than the proposed recommendations. But we believe that gathering support for these relatively small steps could pave the road to more significant actions on a global scale. We called this set of recommendations a Routing Resilience Manifesto – you can find a draft document here: https://www.routingmanifesto.org/. This initial version of the Manifesto was drafted by a small group, but we need a wider community review, your feedback, and, ultimately, your support to make this initiative fly. It was already presented at several venues, like RIPE and NANOG, and now we open it for a more detailed review. Please note that this is very much a work in progress. Please review the document and provide your feedback and text suggestions online or via routingmanifesto(a)isoc.org by 31 August 2014. Regards, Andrei Robachevsky Internet Society
