In the first Scenario we have a single type of traffic with each classes of Service, including the traffic flow for Ping traffic with BE class of service. In the second scenario we generated traffic for all five types of packet which we have in our network; however we apply only a single class of service to all the packets.

It was expected to see the best result in this Scenario
