The future of private infrastructure ownership is moving to a new model combines the old with the new that I describe as “dolls and babies” where the major transformation in infrastructure ownership is the transition from having babies to owning dolls. Infrastructure as Babies Enterprises buy infrastructure like people have babies. It takes months to […]

Lede: In discussions with a stealthy networking startup today, we were discussing how their overlay network technology for the SDN WAN was able to to detect network blackouts and brownouts in the physical network. Their answer was to run Bi-directional Forwarding Detection (BFD) in the overlay tunnels. Now you have effective quality and service detection in the overlay network.

Today’s Networks are auto-configuring and self-orchestrating. When you connect a server to network device, the device will identity the MAC address of the server and update it’s database. The server can make a request to a DHCP server and self configure. A network can be intentionally designed so that multiple paths exist through the network. […]

Can the Internet be the “Cloud Network” ? If so, when could the transition happen (if it hasn’t started already) ?
Supposition/Hypothesis As a technology, the Internet has strikingly similar properties to sharing Compute and Storage as ‘Cloud’. A large pool of resource that can be used or shared between many parties. The total pool of resource is dynamically allocated. Internet bandwidth is shared between all users and access is determined by bandwidth purchased at the network edge

Being a Network Engineer is a hazardous and even dangerous profession yet the Health and Safety division doesn't seem to care about the network damage and prevention.
It's time for us to stand up and start our own ITIL-compliant safety campaign. I've prepared the following handy sign for you to print and place on your cubicle wall to remind you to be safe out there.

No matter how hard the clouderati click the heels of their brogues together and repeat “public cloud is better” , the simple fact is that most companies have large amounts of IT infrastructure that works just fine and is profitable. To make matters worse, the cost of transformation exceeds the potential financial return while creating […]

I was asked to describe how Arista has been able to penetrate the networking switch market relatively quickly. Arista was founded in 2004 and ten years later has achieved a competitive position against all the major vendors in networking and specifically against Cisco who has a dominant market position. Most vendors develop product like an […]
