Based on lessons learned in earlier versions of vPath, and realizing that NSH would only succeed with broad acceptance from a wide variety […]
This is one of a multi-part series on the Ethernet switching landscape I wrote to support a 2-hour presentation I made at Interop Las Vegas 2014. Part 1 of this written series appeared on NetworkComputing.com. Search for the rest of this series. Ethernet switches have been a focal point of software defined networking. As some […]
I attended the Open Networking User Group meeting in NYC May 5 & 6, 2014, attached to Tech Field Day. ONUG was not a super-technical event overall, but it is an excellent chance for folks interested in SDN and open source networking tools to get together and discuss practical matters related to adoption of cutting […]
When preparing for “The Ethernet Switching Landscape” presentation at Interop, I did quite a bit of reading through vendor marketing literature and documentation. One proposed fabric design by Mellanox stuck in my brain, because I was having a hard time mapping the numbers in their whitepaper to what the reality would look like. Here’s the […]
