Cisco CEO Chuck Robbins: Get ready for the network’s next act

Cisco’s annual user event, Cisco Live, is being held in Orlando, Florida, this week. While Orlando is home to DisneyWorld, Universal Studios and other places where fantasies come true, the one thing that isn’t make-believe is the turnaround of Cisco since Chuck Robbins took over as CEO. When the baton was passed to Robbins in August of 2015, Cisco’s stock was trading at about $25/share and had been moving sideways for years. Today, it’s trading at about $45/share and at a 17-year high, and the turnaround is well underway.Cisco goes back to the network How did Robbins get Cisco’s mojo’s back in such a short period of time? The answer lies in its roots and a refocus on the network. In fact, when Robbins took over as CEO, I wrote a post outlining some priorities for him as he stepped into the role. My first point was to approach IT through the lens of the network. In the years leading up to the transition to Robbins, I felt Cisco had tried too hard to prove itself as a server and traditional IT vendor instead of staying true to networking.To read this article in full, please click here

What Is Intent-Based Networking?

This blog post was initially sent to the subscribers of my SDN and Network Automation mailing list. Subscribe here.

Whenever someone mentions intent-based networking I try to figure out what exactly they’re talking about. Not surprisingly, I get a different answer every single time. Confused by all that, I tried to find a good definition, but all I could find was vendor marketing along the lines of “Intent-based networking captures and translates business intent so that it can be applied across the network,” or industry press articles regurgitating vendor white papers.

IDG Contributor Network: Is the IT help desk model broken?

There’s no doubt about it – today’s workers have fully embraced the trend toward remote working. In fact, according to last year’s Gallup “State of the American Workplace” survey, roughly 43 percent of employees report they have worked remotely.  It would seem that the genie is out of the bottle, and it’s not likely to go back in without a fight.This mass migration off premises changes the dynamic between users and IT help desk teams. An operator can no longer run down the hall to ask a user “Can you show me what the problem is with your computer?” More importantly, without having total visibility in the cloud, the operator may be completely unable to ‘see’ any problems that users are experiencing as they work remotely.To read this article in full, please click here

Short Take: Practical Career Advice

One problem I’ve heard in the past is that much of the career advice given in the networking world is not practical. In this short take, I take this problem on, explaining why it might be more practical than it initially seems.

Worth Reading: The old switcharoo

The cost of servers keeps going up and up, thanks in large part to memory, flash, and GPU prices rising as too much demand chases too little supply and also due in part to the rising cost of processors. So the server market is booming. And guess who is actually paying for it? Network vendors, who are being ground down like sacks of wheat in the massive granite grist mill of intense competition. —Timothy Prickett Morgan @The Next Platform

Data freshness, not speed, most important for IoT

The age of sensor data is more important than how fast it takes that information to travel around Internet- and Location-of-Things environments, say some experts. Scientists are, in fact, rethinking the network because of it.“It’s not enough to transmit data quickly. That data also needs to be fresh,” says MIT in a news release.The university has been working on better ways to ensure that sensors, which distribute readings for analysis, provide the most salient stuff. It’s not easy because you can’t just send everything at the same time (an obvious solution) — there isn't enough bandwidth.To read this article in full, please click here
