Cisco made its long-awaited entry into the software-defined networking space in November, acquiring its "spin-in" company Insieme Networks for $863 million.
Cisco calls Insieme "application-centric infrastructure," and by that it means that the overlay approaches to SDN used by VMware, Big Switch Networks and other rivals aren't suitable for the rigors of enterprise usage. Cisco also unveiled a new line of Nexus switches that support Insieme's technology.
The big question now is, will Cisco succeed in its bid to reshape the SDN market around its own need to continue selling high-end hardware? SDN is supposed to democratize networking by letting companies run on commodity hardware, and that's a scenario that Cisco would clearly like to avoid.
