Collection of useful, relevant or just fun places on the Internets for 21st April 2012 and a bit commentary about what I’ve found interesting about them: RFC 6307 – Encapsulation Methods for Transport of Fibre Channel Traffic over MPLS Networks – I’m speechless. FibreChannel over MPLS ( which runs over IP over Ethernet over [...]
Many people have attempted to prove that OpenFlow creates disintermediation of the hardware market dominated by Cisco, Juniper etc. In fact, it’s allow these vendors to bring the very best of their core values to Software Defined Networking.

Everyone thinks that Facebook doesn’t know much about you. But a 1200 page PDF file of personal data seems excessive. And this article explains why it’s bad for your social health if entities can get at that data (usually via Facebook apps). I’m worried, you should be too. Also, Security and Networking Professional should not [...]
VMware testing shows dramatic performance improvements, especailly CPU reduction, when performing vMotion over RoCEE networks. Implications for future network designs are enormous.
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 [...]
