How TRILL (and SPB) Can Reduce STP Risk and Mitigate Impact
In this post, I’m looking at network designs with ECMP cores using TRILL or SPB, I’m realising that STP is equally improved in terms of risk and performance by reducing the STP domain size which leads to better stability, reduced risk and impact mitigation
OpenFlow Might Lower CapEx While SDN Will Increase OpEx
A lot of people have talked extensively about OpenFlow making significant changes to the networking business. In particular, many writers have focussed on the possibility that OpenFlow enables a choice of using low cost network equipment instead of the expensive networking equipment that we use today.
Well, that’s highly unlikely.

Sponsored: Brocade Virtual Symposium – Storage Convergence
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.
Poster: Cloud Price Negotiations
Some time ago, I was asked to work with a Cloud Provider to establish a budget for a potential project. I was unable to set a project budget because there was no way of capping the cost and meeting a budget. This is how the conversations with the sales representative went when discussing “How much [...]
Brocade HyperEdge and “Effortless Network”
Today, Brocade has announced “Effortless Network” strategy[^1] which is their first solid move into the campus networking and replacing the tired FastIron products with the Brocade ICX64x0 switches. It’s a good start even if the strategy won’t really get going until next year.

Internets of Interest for 9th May 2012
Collection of useful, relevant or just fun places on the Internets for 9th May 2012 and a bit commentary about what I’ve found interesting about them: Avantages of Using SVTI Based VPNs | PacketU – Paul Stewart gives a great example on SVTI. (I”m still learning here). Starting in version 12.3T (which is some [...]
Repsonse: Big Switch Networks – The Value of Openness
Omar Baldonado talks about the value of openness for SDN & OpenFlow My takeaway from that panel and the other speakers is that we’ve arrived here at this point in the industry because of the openness of software-defined networking. Many of the components of SDN already existed as the audience pointed out, but it is [...]
Does SDN Represent the Evolution of Network Management ? Yes but No It Doesn’t
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.
