The definition of Software Defined Networking (SDN) continues to broaden, today including functions such as configuration automation and orchestration. While these tasks aren't strictly SDN, the fact is software is used to define some aspect of the network infrastructure in both cases, so vendors have stretched the definition of SDN to bring configuration automation and orchestration platforms into the mix. In fairness, the line gets blurry, as some modern orchestration systems use programmatic interfaces to provision the network instead of traditional configuration tools such as SSH or SNMP.

Followers of Software Defined Networking (SDN) might recognize a sort of market maturation. We don't mean maturity of the product sets, or even how SDN is technically achieved. Those elements are still coming along. We mean vendor SDN strategies are settling in.
One of the key challenges confronting potential users of software-defined networking is discerning the specific value of particular SDN controllers. Controllers, after all, play critical role as the key arbiter between network applications and network infrastructure.
