Note: doublecheck priority!

“An entry must be programmed in flow table 2” → r.TABLE(2)

“Which directs all further packets with MAC source address of the sending server” → r.MATCH(’MAC_SRC’, mac)

“to flow table 3” → r.ACTION(’GOTO’, 3)

Rule with Prio 1 exisits → r.PRIORITY(2)

send_rule(switch, r)

‘The received packet must be sent back to the switch’ → send_packet(packet, switch)

Note 1: you can use for loops, pseudocode

Note 2: DON’T OVERTHINK, simply do the subtasks isolated. Pay attention only for prioritues.
