+== Flowvisor ==
+
+The flowvisor tool server as an intermediary between controllers. It splits traffic based on predefined rules. For our configuration we're running
+flowvisor on SB9. While it is completely possible to complie your own flowvisor from scratch and install it in your home directory, a precompiled flowvisor is located in /opt.  In order to properly steer the flowvisor tool, you must populate a flovisor-config.d directory with files that configure the flowvisor behavoir. For the purposes of this demo we'll be using these files:
+
+{{{
+bittorent.guest
+default.switch
+routing.guest
+}}}
+
+The defualt file primes the flowvisor and contains only the following lines:
+
+{{{
+ # For switches that do not have a their own, specific config file
+ Default: 1
+ # Start numbering "default" switches at 10000
+ Id: 10000
+}}}
+
+The routing.guest file directs production traffic to SNAC running on port 6634, it denies high numbered IP traffic from getting to port 6634:
+
+{{{
+Name: routing
+ID: 1
+
+Host: tcp:localhost:6634
+
+# By default, with now "FlowSpace" param, this slice has
+# permissions to affect all traffic
+FlowSpace: deny: tp_src: 10001
+FlowSpace: deny: tp_dst: 10001
+FlowSpace: deny: tp_src: 10002
+FlowSpace: deny: tp_dst: 10002
+FlowSpace: deny: tp_src: 10003
+FlowSpace: deny: tp_dst: 10003
+FlowSpace: deny: tp_src: 10004
+FlowSpace: deny: tp_dst: 10004
+FlowSpace: deny: tp_src: 10005
+FlowSpace: deny: tp_dst: 10005
+
+# limit 10000 == at most 10000 packet_in's per second == infinity
+FlowSpace: allow:   limit: 10000
+}}}
+
+Finally the bittorent.guest directs high numbered ip port traffic to a controller on 6635:
+{{{
+Id: 1001
+Host: tcp:localhost:6635
+
+FlowSpace: allow: tp_src: 10001 limit: 10000
+FlowSpace: allow: tp_dst: 10001 limit: 10000
+FlowSpace: allow: tp_src: 10002 limit: 10000
+FlowSpace: allow: tp_dst: 10002 limit: 10000
+FlowSpace: allow: tp_src: 10003 limit: 10000
+FlowSpace: allow: tp_dst: 10003 limit: 10000
+FlowSpace: allow: tp_src: 10004 limit: 10000
+FlowSpace: allow: tp_dst: 10004 limit: 10000
+FlowSpace: allow: tp_src: 10005 limit: 10000
+FlowSpace: allow: tp_dst: 10005 limit: 10000
+}}}
