SDN Matures – via the Federal Government…
Based on industry research and market assessments such as the most recent from Allied Market Research, we know software-defined networking is growing crazy fast and has a huge upside. The question is…is it maturing to the point the Federal Government will make it a priority?
I think the answer is YES, based on what Lt. Gen. Alan Lynn, director of the Defense Information Systems Agency has said publicly. And, it appears cyber-security is one of the biggest areas he sees SDN helping out. He explains how SDN can provide the ability to create networks on-demand and make them harder to attack.
In order to help Lt. General Lynn, we needed to get past an issue I like to call, “Barrier of Implementation”. The barrier is an approved DISA STIG for SDN. In order for federal agencies to implement a SDN solution it has to go through some sort of security accreditation. Most of all security accreditation rely on DISA STIGs for the checks and balances.
With our announcement yesterday, “VMware Receives STIG-Approval for VMware NSX to Operate on U.S. Department of Defense Networks from Defense Information Systems Agency,” VMware NSX network virtualization became the Continue reading

How Do I Persuade My Management Automation Makes Sense?
Matt Oswalt made two great points while tweeting about my Automation Gone Wild blog post:
- Automation should be a strategy. You need management buy-in;
- You should have at least one person with strong software development experience in your automation team.
However, life is not always rosy, so @stupidengineer asked:

Stop using legacy mobile audio, especially for conference calls. There are better alternatives. You’re doing your customers and colleagues a disservice by using mobile audio. It’s time we moved on. PSTN is not much better either – switch to VoIP, and give your ears a break from crappy audio connections.
Refresher: Audio Quality Standards
There are many different methods of encoding speech for transmission across networks. There are trade-offs with each, balancing bandwidth, voice quality, and endpoint requirements. The interesting point is that there is not a direct relationship between bandwidth and quality. Half the bandwidth does not have to mean half the quality.
The Mean opinion score test provides a way of ‘scoring’ the quality of a call. 1 is Bad, 5 is Excellent. G.711 encoding has a score of 4.1, which is very good quality, but uses 64kbps per call. GSM has a score of 3.5, which is the minimum acceptable level…but it only uses 12.2kbps. Pretty good tradeoff if you’re in a bandwidth-constrained environment.
But we’re no longer constrained by bandwidth. We don’t need to squeeze that audio call down to only a few kbps. We can use other options such as FaceTime, Continue reading
A Follow Up on SSH Bastion Hosts
This post is a follow-up on my earlier post on using an SSH bastion host. Since that article was published, I’ve gotten some additional information that I wanted to be sure to share with my readers. It’s possible that this additional information may not affect you, but I’ll allow you to make that determination based on your use case and your specific environment.
Agent Forwarding
You may recall that my original article said that you needed to enable agent forwarding, either via the -A command-line switch or via a ForwardAgent line in your SSH configuration file. This is unnecessary. (Thank you to several readers who contacted me about this issue.) I tested this several times using AWS instances, and was able to transparently connect to private instances (instances without a public IP address) via a bastion host without enabling agent forwarding. This is odd because almost every other tutorial I’ve seen or read instructs readers to enable agent forwarding. I’ve not yet determined why this is the case, but I’m going to do some additional testing and I’ll keep readers posted as I learn more.
Note that I’ve updated the original article accordingly.
