SDN: The user view

It is still early days in the emergence of software defined networking, so there aren't many users around to share their experiences and expectations, but there are a few. Network World's editor in chief tracked down Steve Wallace, executive director of InCNTRE, Indiana University's Indiana Center for Network Translational Research and Education, which is already using the technology in a production environment. The school is also playing a role in the tech's evolution.

The promise of software defined networking

If you aren't intimately familiar with software defined networking, don't fret. Only 10 per cent 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.

Google making steady progress in the enterprise

Google Enterprise is making inroads on many fronts, winning converts to everything from its productivity tools to its cloud offerings. We recently caught up with President of Google Enterprise, Amit Singh, for a progress report and to discuss what comes next.

What's next for Wi-Fi?

Wi-Fi is blossoming in the enterprise as organizations find new ways to leverage the wireless infrastructure and workers, having benefited from mobility, demand increased range and better performance (and support for all those devices they are bringing in from home). The industry is responding in kind, introducing new products and technologies, including gigabit Wi-Fi, and it is up to IT to bring it orchestrate this new mobile symphony.

A perspective on IP traffic growth

IT professionals, perhaps more than anyone, have a sense of just how fast things are changing in this information-driven world. But Cisco's latest Visual Networking Index, an ongoing study of global IP traffic, adds perspective that may influence some of your thinking when it comes to long-range capacity planning.

SDN coming ... soon

Software defined networking was a hot topic at the recent Interop conference in Las Vegas, where enthusiasm for the emerging technology overpowered any lingering doubts.

Why don't risk management programs work?

When the moderator of a panel discussion at the recent RSA conference asked the audience how many thought their risk management programs were successful, only a handful raised their hands. So Network World Editor in Chief John Dix asked two of the experts on that panel to hash out in an email exchange why these programs don't tend to work.

Understanding Software Defined Networking

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.

Time is now for Internet retail tax

On the face of it, the bill the Senate is considering to levy taxes on Internet retailers simply makes sense. The states are strapped for cash and we have a bifurcated system that requires local brick and mortar outlets to ante up while letting out of state online retailers off scot free.

Clarifying the role of software-defined networking northbound APIs

What of the oft-mentioned northbound APIs that will let applications tell the controller what they need from the network? What kind of progress is the Open Networking Foundation making on that front? Network World Editor in Chief John Dix put the question to Robert Sherwood, CTO of Big Switch Networks and head of the ONF's Architecture and Framework Working Group.

Gauging BYOD acceptance

The debate about the bring-your-own-device movement (BYOD) has quieted down, mostly because, it seems, while IT has been over in the corner arguing the pros and cons, employees have been streaming into office with their shiny new toys and using them to get work done.

The SDN incubator

A speaker at a recent Network World event asked the crowd of 450 IT practitioners if they were familiar with software-defined networking (SDN) and only about 10 per cent raised their hands.

Who has responsibility for Cloud security?

As more organisations leverage the Cloud for critical business applications, they are discovering one of the greatest challenges is combining existing internal controls with cloud protection efforts.
