 As of now, we assume that there is one module per slice (forwarding, switch, hub...). 
 
-The flow of event handling for messages, compared to the components of Flowvisor, looks like the following in the modified version of Floodlight:
-{{{
-OFSwitchAcceptor             FVClassifier                                     FVSlicer

-                  /                                \/                                                          \

-   receive()  ->   handleMesssage() ->  receive()  ->     write()    ->  handleOutgoingMessage()  ->   receive() 
+==== (7/10):[Floodlight packet processing chain] ==== #fl-2
+The following function calls are made when Floodlight processes a OF Message from a switch:
+
+[[Image(fl-pkt-process-chain.png)]]
+Where the colors indicate the class membership of the function:
+ * green: Controller.java
+ * lavender: IOFMessageListener.java
+ * blue: IOFSwitch.java
+ * yellow: Netty.channel

+The flow of event handling for messages, looks like the following in the modified version of Floodlight:
+{{{
+   FVAcceptor        FVController        Modules        OFSwitchImpl       OFSwitchImpl       Netty.channel.Channel    
+   receive()  ->   handleMesssage() ->  receive()  ->     write()    ->    write(List<>) ->         write() 
 }}}
 receive() in the modules may be called twice, but since message handling varies with OFType, this does not loop as one may think.
