we used the First-In-First-Out (FIFO) queuing discipline in the routers. To analyze the effect of different queuing disciplines, we will create two more scenarios to test the Priority Queue (PQ) and (Weighted fair queueing) WFQ disciplines. Using Lab10 scenario, create two more Duplicate Scenario that are using PQ, and WFQ.

1) Analyze the overlap graphs of the Voice Packet End-to-End Delay and Voice Packet Delay Variation graphs. Compare the three queuing disciplines and explain their effect on the performance of the three applications.

2) In the implemented project, edit the Queues object and check the profiles assigned to the FIFO, PQ, and WFQ disciplines. For each profile answer the following questions:

a. How many queues are associated with each discipline?
b. In this lab, we used ToS (Type of Service) to identify the priority and weight for the PQ and WFQ disciplines respectively. What are the other parameters that can be used to identify the priority and weight?
c. In PQ, how are queues configured to serve different ToS (Type of Service) values?
d. In WFQ, how are queues configured to serve different ToS (Type of Service) values?

3) For all scenarios, choose the "queuing delay <--"statistic for the link that connects East Router and West Router. Rerun the simulation and generate the graph that compares that queuing delay for all queuing disciplines (scenarios). Analyze this graph.
