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, […]

MPLS traffic engineering has many use cases and it helps to solve the problems in an MPLS enabled networks. These use cases are in general; QoS guarantee, End to End SLA , Fast reroute, Admission control and so on. All of them at the end is done for the COST SAVING. The real reason behind MPLS Traffic… Read More »

You might remember my blog post claiming we had a system with SDN-like properties more than 20 years ago.
It turns out SDN is older than that – Rob Faulds found an old ComputerWorld ad from 1989 promoting AT&T SDN service, and it seems SDN was in operation as early as 1985.
In this post, I’ll build on a couple of previous posts and show you how to build your own Docker Swarm cluster that leverages etcd for cluster node discovery. This post builds on the information presented on how to run an etcd 2.0 cluster on Ubuntu as well as the information found in this post on running a Consul-backed Docker Swarm cluster.
To help you follow along, I’ve created a Vagrant environment that you can use to turn up the configuration described in this blog post. These files are found in the “docker-swarm-etcd” directory of my GitHub learning-tools repository. Feel free to use the files in this directory/repository to help with the learning process.
There are 3 major components to this configuration:

I just read story on Medium. It’s a great use of Social Media to achieve something truly useful.
I wish more people would think differently in my line of work. Some days the resounding echoes of “we’ve always done it this way” really give me a headache.

I have great respect for my previous company, Cisco Systems, and truly believe that the company has successfully brought a disruptive approach of applying network technologies to answer major business challenges.
Working at Cisco was like being conferred with an honorary doctorate from an Ivy League school in engineering, management, leadership and entrepreneurship simultaneously . The experience of working in multiple lines of businesses was helpful in shaping the mindset on how best to manage innovations and productize them so that it was mutually beneficial to the customers and the company. This productization often required an intense validation process, which resulted occasionally in some really cool technology ideas not ever seeing the light of day. Thoughts presented for the rest of this blog are an attempt to share my experience and possibly dispel some myths in the industry.
Myth – One Vendor Can Answer All Networking Requirements
Network vendors for the longest time have enjoyed a monopoly (or duopoly). If an organization had some IT infrastructure requirements, there were a handful of vendors that would satisfy all their needs. This was great for everyone! As a measure of risk mitigation, a famous unwritten policy surfaced that “you would not lose your Continue reading
