Several companies have announced they have OpenFlow-enabled switches, but for these companies, there is still no strategy and no reasoning as to why their switch should be used when deploying an OpenFlow based SDN. Furthermore, they lack a strategy overall looking at the various components of a Software Defined Network. From a hardware standpoint, some of the same features and characteristics (buffers, table sizes, etc.) will still need to be compared as we already do today in traditional networks, but even that, isn’t documented in these announcements. A lot of these vendors think they are on the offensive [vs. Cisco] announcing OpenFlow enabled switches (without a controller), but they really aren’t, in my opinion.
