1. Objectives
As a network engineer working for a Service Provider, design and implement QoS on a
converged network. For this project it is assumed that the converged network offers triple play
services and has the following traffic: VOIP, High Definition TV (HDTV), Video on Demand
(VOD) and Internet.
Note 1: The project is based on the experience acquired by the students in the previous labs,
hence the main sources to complete the project are the labs of previous weeks, so it is important
that the students review the lab instructions of the labs that have already been completed.
Note 2: The students will have access to the same lab equipment of Skillsoft as the previous
weeks. The students will need to access the iLab to complete the project.
2. Project Requirements
Part A: Design
In this part the student should provide the QoS design.
A1. It is assumed that the traffic sources for HDTV, VOD, VOIP and Internet are
connected to switch NYCORE1 to four different ports. The following are the requirements:
(10 points)
 Assign a switch port to each type of traffic.
 Assign a COS to each type of traffic. The COS marking has 8 classes, from 0 to 7,
assuming 0 is the lowest priority and 7 is the highest. Decide which class each traffic
should have, based on the importance of the traffic.

2.  Provide your answers in the form of the table below:
Traffic Type Switch Port Number COS
Note that the answers for COS assignments can be slightly different from student to student, as
we have 8 classes but only 4 types of traffic to classify.
A2. Explain in a short answer how or why you picked the highest priority traffic and the
lowest priority traffic? (5 points)
A3. Calculate the total bandwidth required for the following customer profile. (5 points)
It is assumed that the customer subscribed to a package that allows him or her to receive to his or
her residence simultaneously 2 HDTV channels, 2 VOD streams, VOIP, and Internet traffic. The
bandwidth requirements for each type of traffic is as follows:
– One HD channel: 5 Mbps
 One VOD: 5 Mbps
 VOIP: 2 Mbps
 Internet: 18 Mbps
 Calculate and provide the total bandwidth required for the customer based on his
subscribed package above:
Total bandwidth = _______________
A4. Assuming the customer is connected to one FastEthernet port of switch NYCORE2,
assign a port to the customer; it can be any free port from the switch: (5 points)
Customer port number is _____________________

3. A5. The switch has four queues on each port: 1, 2, 3 and 4. Assign a queue to each type of
traffic based on their COS. Assign the percentage of the total bandwidth that should be
reserved for each queue, based on the bandwidth required for each type of traffic, use the
subscribe package description in A3. Provide your answer in the form of the following
table: (15 points)
Traffic Type COS Queue Number % of total bandwidth
Note that the queue assignment can be different from student to student, and for the case of the
project, we assume it is not important which queue is assigned to each traffic type, as long as it
has the right bandwidth percentage for the corresponding COS.
Part B: Implementation
In this part, the student will provide the configuration.
Note 3: Make sure that the QoS is enabled on the switch you are configuring QoS on.
Note 4: Configurations on switch NYCOR1 and switch NYCORE2 are independent, meaning
they can be done in different days for each switch.
B1. It is assumed that traffic sources are connected to NYCORE1 switch. Access iLab
NYCORE1 and enable QoS on NYCORE1. (5 points)
 Provide the configuration steps.
 Provide the verification using show command.

4. B2. Configure traffic classification based on your design from A1, configure the assigned
COS on each port for each type of traffic. (10 points)
 Provide the switch configuration steps.
 Provide the verification of your configuration using show command.

5. B3. It is assumed that the customer is connected to NYCORE2, to the port you assigned in
A4. Access iLab NYCORE2 switch and enable QoS. (5 points)
 Provide the configuration steps.
 Provide the verification using show command.
B4. Basedon the total bandwidth calculated on A3, configure the bandwidth limit on the
switch port which the customer is connected to and you assignedin A4. Note that the total
bandwidth is the bandwidth limit for the customer. (5 points)
– Provide the configuration steps.

6. B5. Configure the queues, by assigning traffic types based on its COS to its corresponding
queue. Use the queue assignment from A5. (10 points)
 Provide the configuration steps.
 Provide the verification using the show command.
B6. Reserve the bandwidth for each type of traffic, use the Shared Round Robing method
and your table from A5. (5 points)
 Provide the configuration steps.

7. – Provide the verification using the show command.
