FlowVisor

From OpenFlow Wiki

What

• FlowVisor is a special purpose OpenFlow controller that acts as a transparent proxy between OpenFlow switches and multiple OpenFlow controllers
• FlowVisor creates rich slices of network resources and delegates control of each slice to a different controller
  • Slices can be defined by any combination of switch ports (layer 1), src/dst ethernet address or type (layer 2), src/dst IP address or type (layer 3), and src/dst TCP/UDP port or ICMP code/type (layer 4).
• FlowVisor enforces isolation between each slice, i.e., one slice cannot affect another's traffic

Status

• FlowVisor is currently considered alpha quality and should not be deployed in production networks.
• That said, we currently have FlowVisor deployed in our production network(!).

Download
