As discussed in my previous blog post, Application-Defined Networking (ADN) is the next level up from SDN, in any network, where ever SDN applies. ADN sits on top of SDN. In an ADN environment, the network is being tuned by apps and for apps. The ‘ADN’ acronym has also been used in the past to [...]
Last week I attended the ATCA Summit to present the concept of Application-Defined Networking (ADN). I also participated to a panel on the future of Openflow with distinguished colleagues from Cisco, Dell and Big Switch Networks. The lively discussion highlighted an important topic, the gap between Applications and Openflow. I believe this gap should be [...]
Part 1: Definition The emergence of “Software Defined Networking (SDN)” triggers a critical paradigm shift in networking: SDN facilitates network virtualization as never before and delivers great benefits to users. However, such benefits over traditional approaches to networking can be fully leveraged only if tangible results for end users are the main focus. Additionally these [...]
Back in May I had the opportunity to post a long blog post titled The Soft Network giving a perspective on the extraordinary industry interest for Network Virtualization and Software-Defined Networks. Last month two other women technologists I respect a great deal wrote interesting comments on the same topic (Cisco’s Padmasree Warrior and Arista’s Jayshree [...]
Last week, Gartner published its “top 10″ list of the most significant emerging trends that will impact data centers and IT from now into the next five years Gartner: 10 key IT trends for 2012. A very interesting list which again largely stressed the impact of Cloud and SDN, a model we understand well at [...]
Network Virtualization and Software-defined Networks (SDN) are really hot, white-hot. But as more and more people try to understand these concepts it seems there is a great deal of confusion.
I attended Interop Las Vegas in May, presenting a demo of our CloudWeaver solution at the OpenFlow Lab. Many people including many network experts came to me with a deluge of questions such as “Why are these technologies considered so revolutionary?” or “Network virtualization is nothing new, isn’t it ?” or “Networks are already ‘software-defined’, aren’t they?”.
April was a defining month for Cloud and Networking people in Silicon Valley with two major events of significant impact for the industry: Open Networking Summit and the OpenStack Conference. Open Networking Summit was a gathering of top players looking at disruptive solutions for creating smart, reliable and cheap networks. Combining the software and virtualization [...]
