Data! NOMA gets air (time) in Budapest

NOMA at RIPE 74

Today I had the opportunity to talk to the RIPE meeting crowd about my use of the RIPE NCC Atlas measurements infrastructure to simulate the NOMA v6 health metric measurement.  NOMA is based on operators instrumenting their networks.  The RIPE Atlas infrastructure, with its probes distributed throughout a variety of networks, is a good platform for illustrating what could be done, with live (if somewhat limited) data.

Routing security: work with what you’ve got!

It seemed like there would be little appetite for discussing next steps in routing infrastructure authentication and verification after the DDoS attack on Dyn (October 2016), when it became clear that large scale attacks are feasible without spoofing IP addresses, hijacking prefixes, or otherwise falsifying Internet infrastructure numbers and routing. Already a tough sell to get operators to consider incremental (let alone architectural) updates to do origin authentication and some manner of routing announcement verification, the Dyn attack provided a clear and present danger that would not be addressed by such updates, so why bother with them?

When do you need a TechArk?

One of the questions that comes up regularly is:  what kind of projects are appropriate for TechArk?

So, here’s a handy little diagram, perhaps even a logo, to keep that in mind.

Necessary… but not sufficient: Are we on the right track for Internet security?

Last Wednesday,  in the hallways of the NANOG 68 meetings in Dallas, I started asking a question that goes to the heart of prioritizing work to improve Internet security; on Friday, with the DDoS attack on Dyn’s infrastructure, we got some searing insight into why it is quite possibly an urgent question.

Measurements of networks: what more could there be in the world?

The TechArk NOMA (Network Operator Measurement Activity) is focused on  developing operator-driven network health measurements through the definition and promotion of self-instrumentation and information sharing.)  This is all with a goal of ensuring a better, shared understanding of what “good” Internet looks like.

An important question is whether there is anything left to measure in operator networks?  At an invitational workshop in June of this year, the answer seemed to be “why, yes, there is”.

Various measurements are made of and across networks today, but they are often done without the specific involvement of the operators of those networks, and therefore have to make guesses or generalizations about them.  On the flipside, there’s a lot that goes into the customer’s experience of the Internet that can be adjusted and improved if network operators have a comprehensive instrumentation of their own networks.

The report from that workshop is now available here:  http://www.techark.org/wp-content/uploads/2016/09/20160831-WorkshopReport-Final.pdf .  Have a read through to see more about the experiences of one network operator that has implemented such instrumentation and possible paths forward to achieve the NOMA goal.

Routing Security — why trust information?

Trust is in the eye of the beholder – but it has to be based on something.   In different contexts, crypto may be more relevant than heuristics, and vice versa.  Traditionally, in Internetworking, business relationships have had a big role in determining whether or not to trust information being offered by another part, whether for routing information or for other network operations.

Measurements: Actors, Expertise and Uses

There are distinguishable roles in establishing, running and extracting results from any set of data about networks.   In some cases, one entity will handle more than one role. In all cases, the access and expertise of the entity impacts how they carry out the role.   That is, the operator of a network is in a better position to understand the network being measured (access), although they may not have as much experiment and analysis expertise as a non-affiliated researcher.   The 3 key roles are:
