Tremendous progress is being made in SDN and OpenFlow, with more and more products appearing, especially hardware-based OpenFlow switching products, and acceptance by network operators and service providers. However, controversies surrounds the question between overlays and underlays, and also on non-OpenFlow protocols on the southbound side and open source software (especially where some elements of code are being extracted to create proprietary products). As for predictions, Dan Pitt believes carriers will embrace SDN, and not just NFV, because SDN underpins NFV and enables its full value, and it also creates revenue growth elsewhere in a network.
