Most in our industry have heard dramatic descriptions of the ways that software-defined networking ( #SDN ) is set to change IP networks. Monitoring and managing those networks is an essential function, but not a glamorous one. If it's part of your responsibilities, you may have given little thought to the impact SDN will have on your work. People who make network management systems (NMS) are spending much of their time lately thinking about the subject. Academically speaking, SDN is primarily about separating the network's control plane from its data plane. Practically speaking, it's also about bringing flexibility and openness to a discipline long held back by a deficit of both. The open SDN movement as exemplified by OpenDaylight brings the best qualities of the open source way to the design, construction, and operation of networks, and management platforms must adapt accordingly.
