Network Simulation using omnet++ -- 2

implement the Backward Learning algorithm in a network of switches.
autonomously.
The procedure is simple and it is executed every time a packet is received. The switch looks at the
the destination address of the incoming packet and:
• if the destination is already listed in its switching table, the switch will forward the packet to the port
indicated by the table
• if the destination is not in its switching table, then it will forward copies of the packet on all of its gates.
The switching table is populated by having the switch write that the packet source address is reachable
through the incoming gate where the packet was received.
