Segment Routing has crossed the chasm – “Early Adopters” have already embraced it, and now the “Early Majority” is adopting it. Interestingly, at the very same time the industry is surfing the Segment Routing MPLS wave, the next wave is already coming in and will even be more disruptive to the way y…

IPv6 as a protocol has been known for a while, but enterprises are beginning to understand the ways in which it can help them achieve their goals, improve efficiency and gain functionality that were hitherto unavailable. When the IPv4 to IPv6 transition first took place, some Internet-scale companie…

Advanced Addressing Scheme Securely Connects Billions of Devices and Things Digitization and automation is now a familiar feature in many homes. Mobile connectivity is not just for phones anymore. Today, we have lots of things that generate data or environments that we want to control (locally or r…

FOSDEM 2017 was again a great success. We did a bit less analysis compared to 2016, but the numbers we got indicate the number of visitors grew significantly compared to last year: the total number of unique MAC addresses went from 9711 to a stunning 11918, an increase of 22.7%.…

You may be pretty familiar with Segment Routing and I bet you’re likely tying it to MPLS as the industry at large has been mainly focused on driving awareness and adoption of MPLS Segment Routing. But did you know Segment Routing could work in a native IPv6 environment? Sounds interesting to you? Le…

As stated in my previous blog on Segment Routing, 2016 marks an inflexion point in Segment Routing adoption. I’m not making this claim in a vacuum. This is actually grounded on multiple Service Providers’ feedback expressed during a Tech Field Day event on Segment Routing held last week in San Jose.…

Now in part 4 we can combine the the IP to MAC address tables together with the user agents, captured by NBAR2 and  exported using netflow. The result of all this logging is a list of MAC addresses, the IPs a particular MAC address was using at a certain time, and the user agents we saw for this IP…

As is our tradition by now a team of volunteers helped out with the network setup and operation of Free and Open-source Software Developers’ European Meeting (FOSDEM). The network was very similar to the one used over the last two years and we wanted to report on the evolution of the traffic we meas…
