Show 205 – Open Source Network Monitoring with OMDistro.org
Network monitoring is one of our most requested topics on Packet Pushers, and this week we take on open source monitoring solutions. Why open source?

Viewing HTTP Headers Using Browser Developer Tools
I often find myself viewing HTTP headers (request and response) at the ‘client side’, which are often much quicker (and safer) than decrypting SSL/TLS traffic on a load balancer/ADC. With the use of SSL/TLS growing rapidly even within private networks and the inability to decrypt PFS/DHE protected traffic, this can often be the only way to troubleshoot. The reasons I […]

RFCs You Should Know: 6250
Most RFCs are deeply technical — and they follow the “Yaakov rule” for intelligibility (if you didn’t write it, or you didn’t sit with one of the authors in a bar someplace to talk about it, you can’t understand it), there are a few here and there every network engineer should know. RFC 6250 is […]

Common Network Design Concepts Part-2
In the first article of this series, reliability and resiliency has been explained. Every component and every device can and eventually will fail, thus system should be resilient enough to re converge/recover to a previous state. Resiliency can be achieved with redundancy.

Show 203 – SDN Policy + Congress with Martin Casado & Tim Hinrichs
This week, the Packet Pushers chat with Martin Casado & Tim Hinrichs about policy. What's policy, you ask? In the context of the software defined data center, policy is the big idea that what an IT system needs to do can be expressed in an abstract policy language. The need for abstraction exists because human beings aren't easily able to tell machines explicitly what they need to do build a system that conforms to a given policy.
