Thanks to […]

 As a Scot, I have a natural predisposition – almost a gene – for money saving initiatives!  As I’ve been researching new initiatives in my work for Cisco Services over the past few months, I’ve become aware of – for the first time I am ashamed to say in some cases – some huge sinks […]

Last week I spent some time at the “Software Defined Networking 2014” conference in London.  It’s a relatively small conference I would say however given the growing interest in SDN and rapid progress of the technology it’s always good to hear alternative viewpoints and experiences.  And I certainly found the previous conference here in December […]
