The Programmable Network: Advanced Flow Control

The increasing diversity and complexity of traffic traversing the Internet of Everything­ today can be imagined as a three-dimensional collection of intersecting highways of different kinds (e.g., corporate WAN, Internet, mobile, Wi-Fi, cellular, cable, cloud), with a wide array of vehicles (e.g., PCs, tablets, smartphones) carrying various types of passengers (e.g., data, voice, video, email, SMS, Web).   Emerging traffic from the new category of machine-to-machine communications is scaling exponentially and introducing new policy triggers.

In this new environment network operators must become master traffic controllers to deal with all of the volume, diversity, and complexity. The most innovative and forward-looking experts are aggressively looking into providing more open programmatic access to their network functions and services. The goal is easier and faster control, in order to make them more agile, flexible and application interactive while at the same time optimally aligning costs with potential new revenues.

Open Networking and SDN perspectives with Dr.Jim Metzler

As the hype cycle around aspects of  concepts like software-defined networking continue, customers are continuing to sift through and educate themselves to determine what is real and actionable.  I have had my fair share of participation in several events over the last 24 months,  and have been speaking to different audiences both gaining and sharing insights in the process.

One person I spoke with recently was Dr. Jim Metzler. We seem to be crossing paths at multiple venues including Interop, the Network World SDN roadshows currently underway in a few cities in the United States, as well, as at the Open Network Summit in Santa Clara a few weeks ago.

Jim has become the messiah of sorts, on some of these emerging technologies, and is frequently consulted -- both as part of his day job at Ashton, Metzler and associates and during his role hosting various industry panels on these topics. I thought it would be good to host the host and get some of his perspectives here, as we both got together at the recently held Open Networking Summit at Santa Clara.

The Programmable Network: End-to-End Visualization and Control

In our last blog, we talked about the next generation Internet. It will be about the Internet of Everything­ ─ people-to-people, machine-to-machine, machine-to-people, trillions of things coming online in coming years. Software Defined Networking (SDN) is only part of the overall solution.  Real-time intelligence, automation and orchestration, instantaneous responsiveness, and unprecedented business and operational agility require a much broader approach. At Cisco we’re already creating the network of the future with our integrated framework, the Cisco Open Network Environment (Cisco ONE).

So now let’s come down to Earth and explore what all of this really means to an average service provider. What new capabilities and use cases does Cisco ONE enable right now?  How does what we’re doing lay another building block for the Internet of Everything?

OpenDaylight: The Start of Something Big for SDN

April 8, 2013 at 4:08 am PST

So, after weeks of biting my tongue through what seemed like a constant drip of leaks and rumors, we can finally take the covers off OpenDaylight.  So, lets cover some of the basics:

What?

OpenDaylight is an open source project formed under the Linux Foundation with the mutual goal of furthering the adoption and innovation of Software Defined Networking (SDN) through the creation of a common industry-supported framework--essentially we are building a open source SDN stack.

Who?

This is the cool part--the Project has drawn members from across the industry.  Its actually been pretty interesting working with all these companies towards a common goal over the last few weeks--kinda like an all-star team. This is an open project, so any company can join the project at any time and any developer can get involved.

Programmable Networks Will Power the Internet of Everything

We’re 13 years into the new millennium and we still don’t have flying cars, house cleaning robot maids or refrigerators that talk back to us.  Not everything predicted for our Jetson-like future came true — or maybe not as quickly as expected.  Yet, that doesn’t mean it won’t happen.   Our industry talked about triple play voice, video and data services for more than a decade.  Today we watch videos or TV on smart phones, tablets, PCs and television sets while texting friends, playing games or surfing simultaneously on any number of devices from anywhere.   Technology has a way of catching up to our vision of the future.  So don’t bet against innovation.

The next big thing is the Internet of Everything (IoE).  It’s one part evolution and one part revolution.   Network traffic is migrating from people-to-people communication to people-to-things.  The network shift to machine-to-machine (M2M) or Read More »
