In a recent blog post (Will OpenFlow Software Unlock the Switch Market?), Gary Lee of Fulcrum Microsystems considers the implications of OpenFlow upon the switch market. The post notes that OpenFlow “breaks the software lock that some switch vendors have with their system customers”. Indeed, OpenFlow enables companies to develop controllers without developing their own hardware; controllers will interoperate with OpenFlow-enabled switches from any hardware vendor. We (the OpenFlow team at Stanford) expect that this will have a dramatic effect upon innovation as it enables companies to much more easily deploy new services within their networks.
We’re glad to see the increasing interest being shown in OpenFlow by industry, and we eagerly look forward to the availability of more OpenFlow-enabled hardware.
