Improving Mean Time To Innocence With ThousandEyes
In the case of troubleshooting poor performance for an off-site application, improving mean time to innocence is really important. Businesses need to understand whether the problem is in the local infrastructure, in the remote cloud, or somewhere in the middle. This is not especially easy to track down by hand. Manual traceroutes, simple ping tests, and DNS resolution checks are most of what can be done with the average workstation, but in fact there is a great deal more information that is publicly accessible.

HTIRW: Reality at the Mic (3)
Let’s take one look back over the IETF before we move on to the next piece of the infrastructure of the ‘net. Why does it take so long for a single document to get through the process, and result in a standard? There is, of course, the formal process, which requires the document to proposed, […]

RFCs You Should Know: 5218
Quite often RFCs in the “earlier days” discussed not only process but also design. Looking back now, considering the complexity of the network engineering world, these RFCs might seem even a little trite. But these “architectural RFCs” often still carry thoughts and records of experience that are important, even if they aren’t so much followed […]

Smarter Hosts Would Make A Simpler Network
(or Magical Things I Would Do if Hosts Weren’t Stupid) Introduction I’m a firm believer that many of the apparent problems in networking today are caused by stupid hosts. The hosts are stupid and, we are told, cannot be fixed. Instead, we are forced to add on more and more “intelligence” to the network. This […]

Getting Ansible to talk to your Cisco devices
As a listener to the podcast you’ve probably heard about Ansible once or twice already. In short Ansible is a simple IT automation tool. It’s often mentioned together with Puppet, however a big difference is that Ansible is agentless. Using Puppet assumes that you have a Puppet agent installed on the nodes that you want […]

HTIRW: Reality at the Mic (2)
Last time we talked about a few things that go wrong in the IETF — this time we’ll talk about a few more things that can go wrong. Boiling the Ocean. Engineers, as a rule, like to solve problems. The problem is we often seem to think the bigger the problem, the better the solution. […]

Show 231 – OpenFlow’s Possible Futures with Curt Beckmann
Seen as a unifier and enabler in its early days, OpenFlow has come up against some adoption barriers in the form of silicon challenges and vendor-specific extensions that has resulted in a marketplace of OpenFlow options awash in inconsistency. How does OpenFlow rise above this current state of things? Or does it? The Packet Pushers discuss with Curt Beckmann.
