Ping is probably the most popular network troubleshooting and monitoring tool. It happens very often that to test reachability, we have to ping many destinations. The usual requirement is to ping something not from one, but multiple sources on internal network, and sometimes from internet. To be able to do it, we have to have accounts […]

Last month, the announcement was made that after seven years, Netflix completed its move to the cloud. While offering my sincere congratulations to Netflix, it begs the question what chance smaller companies have of moving successfully to the cloud.
I love it when a plan comes together; it’s great seeing multiple threads in different places intersecting, and the news from Netflix pulled together a few things from the last 12 months in a rather interesting way.
I first heard about the Netflix announcement by listening to the Packet Pushers Network Break
episode 74. I don’t have enough time to keep up with all the industry news direct from all the sources out there, so I try to listen to podcasts on my drive into work. Network Break is one of my favorites, with Drew Conry-Murray and guests rounding up the week’s news and sharing their opinions.
The Netflix announcement explained that the company migrated from a monolithic app to hundreds of micro-services.
Rewinding the clock to ONUG Spring 2015, I listened to a presentation from Battery Ventures’ Adrian Cockroft, in which he espoused the benefits of containerized micro-services. The idea is that if Continue reading
In this episode of Network Matters with Ethan Banks, learn why Ethan's advice to most enterprises is to stop thinking about SDN. Rather than viewing SDN as a shrink-wrapped magic solution, Ethan explains why enterprises need to focus on their specific business problems and the networking products that can solve them – SDN or not.
Ethan is the co-host of the Future of Networking Summit at Interop Las Vegas. Learn more about the conference program or register for Interop, May 2-6 in Las Vegas.
From open source SDN like OpenDaylight to Cisco ACI and VMware NSX, enterprises have many choices in SDN platforms.
Recently, a friend pointed out that an individual had taken one of my cheat sheets, superimposed his own logo and URL on it, and published it as his own work. This is certainly not the first time I've been plagiarized, nor will it be the last, I suspect. I called out the individual on Twitter, and I'm very gratefully for the many people who helped me compel him to remove the illegitimate content. Eventually.
I wanted to write a quick post sharing my thoughts on this incident for the benefit of everyone who has expressed interest in starting their own blog or web site. I've heard plenty of people comment over the years to the effect of, "Why bother starting a blog if someone's just going to harvest the RSS feed and re-publish it on their own site to make a few bucks?" Indeed, this has always been a concern among producers of both free and paid content.
I wish I could tell you that plagiarism isn't that big a deal, or that it won't happen to you. But the truth is plagiarism is a huge problem in our industry (and across the Internet in general), and if Continue reading

Let's face it, security is overcrowded.
In December of 2014 I wrote an article about a legal agreement that was discouraging network operators from implementing an important Internet security function. I am happy to report, the situation has improved: ARIN no longer requires operators explicitly accept a click-through agreement in order to access the Trust Anchor Locator (TAL).
