Last year, I wrote a long post on doctrine. I was reminded of that post three times this week. The first was from a Plexxi sales team who was telling me about a potential customer who was going to build a traditional switched hieracrhical network as test bed for SDN.

The second occurrence was in a Twitter dialog with a group of industry colleagues across multiple companies (some competitors!) and one of the participants referenced doctrine as a means for incumbents to lock out competitors from markets. The third instance occurred at the at the Credit Suisse Next-Generation Datacenter Conference when I was asked what will cause people to build networks differently. Here are my thoughts on SDN, networking, doctrine, OPEX and building better networks.
