This week the SDN buzz was about the new executive director for the OpenDaylight Project (ODP). The Linux Foundation announced Tuesday that former VMware executive Nicolas "Neela" Jacques is now the first ODP Executive Director. Jacques hopes to serve as a facilitator of the project, and as a member of ODP, Plexxi thinks this will only benefit the project and accelerate the results. We look forward to seeing what Jacques contributes to this role. In other news, Plexxi has a new channel on SDNCentral, which you can follow for the latest news and videos from us. In Plexxi's own featured video this week, Dan Backman explains what kind of software is still resident on the physical switches and what capabilities are included in that software. Here is the video of the week and a few of my reads in the Plexxi Pulse – enjoy! The Return of the IT Generalist Michele C... (more)

Closing the Bio Gaps in Networking

Network Virtualization: Size Does Matter

A little while ago I wrote about the differences between routing and switching, or probably more the difference between ethernet and IP forwarding. The focus of that article was very much on the differences between the two from a forwarding hardware perspective. This article last week from Brent Salisbury triggered a bunch of additional thoughts around scale and size. As some sense of disclosure, in my previous job at Nortel/Avaya I was part of the team that pushed Shortest Path Bridging (SPB) spearheaded by Paul Unbehagen. I am a fan of SPB, I believe it is an extremely well th... (more)

A Cisco-Insieme primer: What is application-centric infrastructure

With the launch of Cisco’s software-defined networking startup Insieme expected tomorrow, our industry is about to hear a lot about “application-centric” everything. So what does “application-centric infrastructure” mean? First, some basics: Networking is about connecting computing devices and systems so they can share data. Networking infrastructures are built with a combination of hardware such as gateways, routers, and switches that manage the movement of the data as well as software applications that enable you to do things like access the Inter...
