In consumer marketing we are familiar with the concept of giving a way one product (or selling it at a heavily discounted price) in order to build a market for even larger sales of another product. Giving away the razor to sell the blades is the classic example, and a more modern one is giving away the printer to sell the ink cartridges.
The first two attendees that I spoke with last week at NGON Africa in Cape Town expressed often held views that leading edge technology does not apply to Africa. The first was a young technologist who came by as we were unpacking equipment for display at the ECI booth. He asked about the hardware and I explained the 100Gbps transponder that we had installed in a 3RU Apollo™ shelf. His reaction was, “I can’t imagine we need anything that fast in Africa.” The second was a critical infrastructure operator who explained that he was not convinced yet that Africa was ready for the move from copper to fiber.

Through this (probably far too long) series on SDNs, we have looked at BGP, Fibbing, and Openflow. BGP and Fibbing would be described as augmented control planes; the distributed control plane is not replaced, but rather augmented with a controller that modifies the best path decisions of the control plane by interacting with the control itself in a somewhat “native” way.

In 2012, an executive who worked for one of the largest European service providers shared his dream with the attendees of Layer123’s first software-defined networking (SDN) & OpenFlow World Congress in Darmstadt, Germany. According to him, the reason for all the misery in carrier-land were not permanent price battles, flat-rates, and cut-throat competition; it was us, the vendors.
Openflow is the “father of software defined networks” in the minds of many engineers. To understand Openflow, however, you cannot just look at the protocol itself; rather you must go back to the beginning, in the mists of old networking.

The SDN Controller concept was originally developed as the intelligent centralized point of network control and programmability in an SDN environment. However, the name was very quickly adopted by several vendors who claimed that their traditional NMS was a “controller” because it allowed network-wide management and point-and-click provisioning of their equipment. As a result, for many people the line between an NMS and a Controller is blurred, resulting in confusion across the industry.
