Enterprise Network Design and Management Assessment Answer

Students Application Portal System

The School of Computing accepts student applications from different parts of the world. Currently, there is no means for applicants to get updates on the progress of their application processing. You have been asked to design a web-based application processing tracking system which will allow applicants to be able to log into the system and see what is happening with their applications.

The designed system should allow an applicant to register, select a course, complete an application form, upload documents and submit the application. Applicants who have already submitted application forms should be able to log into the online application portal, view their complete application processing history from submission. This should include which University admissions team or individual that has taken any action or made a decision in connection with the application right up to the current status of the application. For all members of staff who process applications, the system must provide a field for authorised staff to enter status information (one which can be seen by the applicant when s/he logs in and one which can only be viewed by authorised staff). Each eligible member of staff should be able to email an applicant from the designed interface without having to open a separate e-mail client. The system must be able to produce a list of applicants grouped by course, level, application status, year in which the applicant wants to start studies, etc.

In this coursework, you are required to design the system, which can be implemented later on. You will assume that your role is to design the system providing all necessary specification that will guide a programmer to write the code. Additional information is provided in Section 2.3.

Introduction

OPNET Modeller is the industry’s leading network modelling and simulation environment, allowing you to design and study communication networks, devices, protocols, and applications with unmatched flexibility. The modeller is used by the world’s most prestigious technology organizations to accelerate the R&D process.

Aim

The aim of this experiment is to familiarize the students with the Opnet Modeler network simulation software package.

Coursework 1

1. Is it important in network design to know how to simulate more than one scenario for the one network? Briefly explain why.

2. When configuring the traffic, you need to set up an item called, "Mean outcome", how do you find and set it?

3. Explain what factors other than network traffic loading & message transit delay times would likely to affect network performance?

4. Which of the following configuration do you need to do first?

a. Application configuration

b. Profile configuration

c. Doesn’t matter

5. How do you impose traffic loads?

6. What is the main difference between application configuration and profile configuration in OPNET?

7. If the simulation is successful, how many entries should be logged in DES Log?

8. How do you get results to compare more than two scenarios?

9. After two successful simulations, you now have two sets of results, one for the initial work and one for the 50% higher loaded work, please attach one graph from each scenario and briefly discuss the differences between two results.

10. Considering the computer network presented in the simulation is a nationwide bank, prepare a full tradeoff table and discuss each technical goal.

Coursework 2

Task 1: Mapping AS/Internet Relationships

1. Choose one stub, one large ISP and one tier-1 ISP and note their ASN and IP prefix advertisement.

2. Note how they are connected (the number of connections)

3. Note the prefix size distribution, transits distribution and the AS path length to the collectors.

4. Trace three hops away from the AS that you are currently in.

5. Perform one or many traceroutes to identify the number of hops to an IP address in the AS three hops away from your current AS.

Task 2: AS/Internet Design and simulation

Adding Traffic

You should add the application config and profile config nodes. Set up two applications, HTTP:Image Browsing and FTP: High Load (but you must edit the inter-request time to “exponential(36)” instead of “exponential(360)”). You should set up one profile that utilises these applications simultaneously. You should set up the LAN in AS11 to use that profile. You should then set up the server in AS55 to support HTTP and the server in AS44 to support FTP.

Experiment 1

1. You should verify that both HTTP traffic and FTP traffic is flowing in the network and you should verify the route that the traffic is taking.

Configure BGP

You should configure BGP between each AS (please use the guidance provided in Lab 4 to achieve this). The internal connection between the border routers in AS22 and AS33 should not use BGP, but should use RIP or OSPF.

Experiment 2

1. You should verify that both HTTP traffic and FTP traffic is still flowing in the network and you should verify the route that the traffic is taking. 

2. You should verify the BGP is being used correctly to update routing tables

Experiment 3

1. You should verify that the next-hop address in the routing table of AS11_ASBR for server in AS44 has now changed. 

2. You should also verify that the amount of traffic between AS11 and AS22 has changed (and verify why local_pref is referred to as an “out-bound” traffic engineering technique). 

Report part 3

You must ensure that the minimum that you record in your report is the evidence (screenshots) that you have completed the task with brief explanation to each. Ideally you want to document problems, how you identified problems and how you overcame those problems.

Experiment 1

1. You should verify that both HTTP traffic and FTP traffic is flowing in the network and you should verify the route that the traffic is taking.

Experiment 2

1. You should verify that both HTTP traffic and FTP traffic is still flowing in the network and you should verify the route that the traffic is taking.

2. You should verify the BGP is being used correctly to update routing tables

Experiment 3

1. You should verify that the next-hop address in the routing table of AS11_ASBR for server in AS44 has now changed.

2. You should also verify that the amount of traffic between AS11 and AS22 has changed (and verify why local_pref is referred to as an “out-bound” traffic engineering technique).
