Openflow at the Virtual Wall

Interfaces of some nodes of the Virtual Wall which are not connected to the big VLAN switch, are connected to a PICA8 P-3290 Openflow switch. The switch is connected to a FlowVisor, which is being programmed by a Foam Aggregate Manager.

The nice thing about the Virtual Wall, is that you can combine topologies on the Virtual Wall itself (with Open VSwitch) with this PICA8 switch.

Port connections

The following nodes are connected to the Openflow switch with (node name and port on switch):

Openflow Request RSpec

jFed can load these RSpecs, as shown in jFed openflow support . An example Rspec (you can run your Openflow Controllers on Virtual Wall nodes and then specify those IP addresses in this RSpec):
