FOSDEM 2019: a new view from the NOC

Cisco analyzed the network and traffic at FOSDEM, the Open Source Developers conference, to determine what 'state of the art' traffic looks like. The data provided insights into future trends.

FOSDEM 2017: a view from the NOC

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%.

Fosdem 2016, part 4: what netflows tells us

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 […]

Fosdem 2016, part 3: enter the netflow

In the last part we used NBAR2 to classify traffic. To do this the router need to investigate every traffic flow which it sees. Of course, it would be interesting to get this information out of the router and into some logs. This is the ‘how we did this’ post and it is a bit […]

Fosdem 2016, part 2: NBAR 2 gives insights into the protocols used on the network

Continuing the analysis of the data collected during Fosdem 2016. This year, we replaced the router with a more powerful model: an ASR 1006 with RP2 and SIP20 modules. This allowed us to enable the NBAR 2 feature to analyse the traffic crossing the router. NBAR 2 is a traffic analysis engine which allows the router […]

Fosdem 2016: a first quick look

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 measured. This […]

Fosdem 2015: a status update

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 last year and we wanted to report on the evolution of the traffic we measured. First the bad news: […]

FOSDEM 2014: Cisco Powered World First

For a few of us in the Cisco Brussels office the last weekend of January always marks a special occasion. The weekend is dedicated to the Free and Open-source Software Developers’ European Meeting (FOSDEM) conference in Brussels, with around 5,000 visitors attending. The event happens at the ULB (Université libre de Bruxelles) campus, but traditionally […]
