Understanding Software Defined Networking

If you aren't intimately familiar with Software Defined Networking, don't fret

If you aren't intimately familiar with Software Defined Networking, don't fret. Only 10% of 450 IT practitioners at a recent Network World event raised their hands when asked if they understand SDN. But if the emerging technology lives up to its promise to redefine networking as we know it, there is no time like the present to dig in and learn more.

Proponents argue that, among other advances, SDN will centralize and simplify control of the network, make networks programmable and more agile, and create opportunities for policy-driven supervision and more automation.In short, SDN will help networks keep up with the speed of change made possible by the virtualization of other data center resources and provide the perfect complement to cloud computing.

But challenges remain. Many of the vendor cheerleaders, after all, are tiny startups. While the incumbents seem to have joined in the chanting, only time will tell if they are serious about change or simply paying lip service while working behind the scenes to scuttle advances so they can get back to business as usual.

That said, most industry pundits say the SDN movement has momentum now and, even though we're still in the early goings, there won't be any stopping this train. Now it is just a question of where we end up going, how long it takes to get there, and how different the coach looks when it finally arrives.

Download this Network World Digital Spotlight, "Understanding SDN," for our in-depth look at the fundamentals, including a piece that explores the promise and the limitations of SDN, another looking at the core building blocks, and an SDN FAQ. We round out the package with a discussion with an early user and 12 tips for SDN IT buyers.

HP OfficeJet Pro 8730

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

Windows 10 for Business / Dell XPS 13

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

Windows 10 / Lenovo Yoga 910

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
