PING (Two way Communication)

Figure4-6

In PING (Two-way communication), almost all the steps are same as PING (One way communication), except that in NetSim Emulation server there will be two applications instead of one. One Application will be directed from Source to Destination node, while the other application will be directed from Destination to Source node.

The difference caused in the network behaviour is that in the first case (PING -One way communication), the PING reply packets were not routed via NetSim Emulator. But in the second case (PING -Two-way communication), the PING reply to packets will be routed via NetSim Emulator, thereby the total delay will be approximately 21milliseconds.
