Juniper to purchase WANDL and why it's important
It was recently announced that Juniper Networks would be purchasing WANDL, a long time partner and

Networks are insecure. Here's why.
Networks are insecure, they just are. I once worked with an FBI agent who said that if you wanted a secure network you should turn everything off, smash it, then set it on fire - and I don’t disagree. However, there are things we can do to understand our networks that will aid immeasurably in how they are secured and initially and how they remain secured over time. At their very core networks are not secure based simply on the fact that humans are involved in their construction, operation, and use.

NIX4NetEng #3 - Tracing paths
Another useful bit of information is the path. Traceroute is fine, but it’s a bit of a “one and done” kind of tool. I prefer to use mtr because it can run for any amount of time I need it to and keep the statistics for the entire time viewable. It does require socket access, so you’ll either need root or sudo in most cases. (~) jumphost $ sudo mtr 192.
NIX4NetEng #6 SALT
Like most network engineers that have been around long enough, I manage a handful of unix-like systems. As I have done work for service providers all over the place for the last 15 years, I have accumulated enough systems out there that need patched and maintained. I like to to send out a raspberry pi to as many ASNs as I can, enabling the poor-mans NLNOG Ring that only I manage.
OpenFlow migration paths
SDN gateways have a much more traditional look and feel. They have a flat SDN OpenFlow network with a default gateway for client traffic by either controller proxy or direct reachability by the client host. Note that both approaches suffer from lack of adoption and maturity, which adds risk to any early production SDN. IPv6-like
perfSonar and Rasberry pie.
PerfSonar tools on a raspberry pi
I want to preface this by saying that this was an experiment for me. That said, I know there are folks that want to run everything under the sun on a pi. So, since I love the platform as well, I set out to try to make the raspberry pi a perfsonar “probe”.
