BPDU Guard and Root Guard are enhancements to Spanning Tree Protocol (STP) enhancements that improve the reliability of the protocol to unexpected events ad are primarily to ensure design enforcement ( integrity / security). There they must configured in specific locations in the networks.
Continuing the series from the Brocade Virtual Symposium. In a special video session that was sponsored by Brocade, we got Chip Copper in the room with Stephen Foskett to talk about storage convergence.
Over the last few years, I’ve been very critical of Ethernet storage protocols like [FCoE](http://etherealmind.com/tag/fcoe/) and the fact that storage protocols are unlikely to work well. There are few times here where Chip was able to give me answers and a different viewpoint that gave me a different take on the solutions.
SDN/OpenFlow is about Network Management, at least, in part. But the rich tools for software control dont’ exist. I also think don’t think that todays management _platforms_ (such as Tivoli, OpenView and BMC) are suitable for network orchestration in the future.
Juniper QFabric is a new approach to Ethernet Switch Fabrics. When it was announced last year,it was noted that the underlying physical design is a completely different approach to building Switch Fabrics. Here I’m taking a loosely research based approach to understand how Juniper QFabric is different from all other approaches to the problem, and also a look at some of the challenges ahead.
Had a few conversations, and some articles, where comparisons are being made between Embrane and Nicira and wanted to point out that there are few similarities between these companies.
