Do you really need to understand the guts of an Ethernet Switch?

This week I read a perfectly reasonable article by Tom Hollingsworth, which then deteriorated in the comments section to a “you don’t know how a switch works” exchange. Both participating parties miss the boat on several of their comments, but the far more interesting question is why we all of sudden need to understand the […]

The key to OpenDaylight adoption: salespeople

The primary indicator of success is success. That is to say that the number one thing people look to as a predictor of future performance is past performance. In the product space, this means that things like adoption are important as much for what it signals to other people as they are for bottom line […]

At the office, are you a doctor or a patient?

Everyone experiences challenges at work. Whether it’s an individual contributor or the CEO, everyone has to go through the same basic set of issues that plague virtually all workers everywhere. But not everyone handles those problems the same way. Conversation is the usual outlet for most people. But how you conduct those conversations says a […]

Automation through workflow state

The benefits of automation are well understood: more agile service provisioning, faster time to insight when there are issues, and a reduction in human error as manual interaction is reduced. Much of the premise behind long-term SDN architectural advantages is steeped in the hope that SDN will help enable and ultimately promote automation. But while […]

Plexxi Pulse—SDN Edges into Federal Agencies

As SDN gains traction within the private sector we are also seeing federal agencies adopt it as they identify the need for network infrastructure changes. While it may be instinctual to say ‘yes’  to upgrading the network to include every new additional feature offered, especially when managing large amounts of traffic, focusing on simplicity and […]

What is 25 Gigabit Ethernet and why would you want it?

In the past few weeks you may have seen several press releases and articles talking about 25 Gbit Ethernet. Just when you got used to ethernet speeds being a nice decimal based system where we simply add zeros every few years, someone threw in 40GbE a few years ago. And that’s ok, powers of two […]

Scaling Big Data fabrics

When people talk about Big Data, the emphasis is usually on the Big. Certainly, Big Data applications are distributed largely because the size of the data on which computations are executed warrants more than a typical application can handle. But scaling the network that provides connectivity between Big Data nodes is not just about creating […]

Scenario planning for first-line managers

A common meme in the strategic planning world is that there is no one pre-determined future. The objective in strategic planning is not to forecast a single outcome but rather to identify a number of possible outcomes. Preparedness comes in having thought through multiple possible end states, and agility comes from the ability to quickly […]

Network abstractions need equivalent of packet walkthrough

Whenever a new networking platform is evaluated, one of the early sales calls includes a packet walkthrough. In excruciating detail, someone walks the customer through the path a packet takes from ingress port, through the device, across the switching or routing ASIC, and back down to the egress port. The technical deep dive frequently includes […]

PlexxiPulse—SDN in the Era of Automation

We hope you were able to tune in to our latest installation of DemoFriday with SDNCentral. In the webinar, our own Marten Terpstra and Andre Viera with Ramen Sud and Sam Gopal of Iron Mountain discussed how SDN provides the flexibility and balance essential for managing transport between datacenters. We’ll share the full webinar once […]
