10 Software-Defined Networking Architectures, September 27, 2013 Software-defined networking is a hot topic for debate in the industry. Experts argue about the best way to implement it, the ways it might affect network engineers and administrators, and how it might disrupt the traditional power structure in the networking industry. While there are a lot of opinions about this emerging technology, there's one inescapable fact: SDN has brought new attention and innovation to the network. To get a view into the various approaches to SDN, we asked 10 vendors to supply images and short descriptions of their SDN technology. While there's some marketing fluff in some of the write-ups, the images provide a window into the wide range of technical approaches to SDN.
Pica8 takes an open-source approach to the controller layer, by leveraging more than seven controller initiatives, including Ryu, Floodlight and NOX, and selecting a controller that best matches the customer's application needs.
Pica8's network operating system, PicOS, provides this functionality on top of commodity white-box bare metal switches. PicOS has OpenFlow 1.3 support, through Open vSwitch (OVS) v1.9 integration. OVS runs as a process within PicOS, and provides the OpenFlow interface for external programmability. It also exposes Debian Linux, so enterprises can use their existing tools for programming and optimizing Pica8 open switches to support their network.
