“Everything is down! The whole network!! RUN AWAY, RUN AWAY!” Yes, we’ve all had those terrible days in networking, where no one can get to anything & it’s all up to you to get it fixed. At least management is there to help, stomping their feet, making demands, and whining about the dollars lost per […]

Maximally Redundant Trees

We’ve come almost to the end of our little series on fast reroute; in this episode we’ll look at maximally redundant trees (MRTs) — this episode is going to be a little “graphy,” so get your seatbelts on. The general idea behind IP fast reroute is to precalculate a set of alternate paths that can […]

Healthy Paranoia Show 20: SDN – Heretic of Security

The known universe has been ruled by the monolithic network device. In this time, the most precious substance in the Universe is the  ASIC. The ASIC extends life. The ASIC expands consciousness. The ASIC is vital, it provides the ability to fold space. That is, travel to any part of the network. The ASIC exists […]

Fast Reroute Mechanisms

Network reliability is an important measure for deployability of sensitive applications. When a link, node or SRLG failure occurs in a routed network, there is inevitably a period of disruption to the delivery of traffic until the network reconverges on the new topology. Fast reaction is essential for the failed element. There are two approaches […]

Switching to Linux for… Switches?

Like many folks out there, I’m following the rise of “whitebox switching”, and am interested to see if (and where) it takes off. There’s many players out there who are trying to pitch disassociating the software from the hardware, and quite a few hardware manufacturers that are offering various hardware platforms on which to run […]

Hadoop for network engineers part 2 – adding more nodes

In the first article here, I walked through importing netflow data into a single Hadoop instance (pseudonode) and mentioned a progression of the project to add multiple nodes. The ability to do distributed storage and distributed processing of data is ultimately the benefit of using Hadoop/HDFS. So, let’s expand on the project and add one or […]
