Incremental SDN: Automating Network Device Configuration

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.
