week 6 course proj


Course Project (80 points)

QoS Design and Implementation

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.

- 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 _____________________

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.

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.

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. Based on the total bandwidth calculated on A3, configure the bandwidth limit on the switch port which the customer is connected to and you assigned in A4. Note that the total bandwidth is the bandwidth limit for the customer. (5 points)

- Provide the configuration steps.

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.


- Provide the verification using the show command.

iLAB STEPS

Step 1: iLab and Report Guidelines

Back to Top

Follow these guidelines to successfully complete your iLab and iLab report.

  1. Use the lab report template for all of your labs. Do not turn in separate documents for each lab or create your own document. Each lab is easily identified within the document by an appropriate section title. Note: It is a good idea to read over everything in the lab report template before performing your labs so that you know what to expect.
  2. Make sure that you read, understand, and follow all steps in this week's iLab page, as well as all iLab instructions.
  3. For labs that require screenshots or show command output, have your lab report open, along with your instructions, so that you can immediately capture the screen, or the show command output and then paste it in your lab report before moving on to subsequent steps. In many cases, it is difficult to go back and capture an accurate screenshot after you have moved beyond the step requiring the screenshot.
  4. Your screenshot or show command output request may be accompanied by an additional written requirement. If so, be sure to respond. Write in complete sentences and be complete in your answers.
  5. When asked to summarize what you learned, always provide well-written, college-level paragraphs that include well-formed sentences, along with proper spelling, grammar, and punctuation. Don't just identify the steps that you performed (we already know that); give it some thought. In your summary, include what you accomplished in the assignment or lab, what you learned from performing it.
  6. Always append your name to your lab report before saving. Submit your completed lab report to the appropriate weekly Dropbox.

iLAB OVERVIEW

Scenario and Summary

As a network engineer working for a service provider implement some advanced QoS configurations, to give more flexibility to the design and connectivity of application servers in a triple-play network.

In the Week 2 iLab, we configured traffic classification based on the assumption that every type of traffic was connected to one interface. So it made sense just to have one default classification and mark all the traffic the same for each port.

For this week's lab we assume that the VOIP, TV, and Internet traffic are all coming to the same port. There are many cases like that, as an example, you might have a firewall between the servers and the switch, and the firewall does not support QoS, meaning after the firewall the traffic will lose its marking, and we have to do the classification and marking after the firewall. The firewall will be connected to the switch using only one port where all the traffic goes through.
