4. Assessment Details.
Background
The Sydney International School of Technology and Commerce (SISTC) recently had gone through a partial renovation. The school has now 4 levels. According to the new layout, the level one has 10 Personal Computers (PCs) in a reception room and 15 PCs in a conference room. The second level has a classroom with 30 PCs, a computer laboratory with 40 PCs, and five staff offices consisting of 5 PCs. The third level has two research laboratories for doctorate (PhD) students, with 20 PCs (each having 10 PCs). The fourth level has 8 staff offices and a lecture room. There are 8 PCs in staff offices and 7 PCs in the lecture room. All PCs are equipped with two types of connectivity to the internet i.e., wireless and wired connectivity. The SISTC plans to carry out multimedia sessions (lectures and labs sessions) within the building where the staff can deliver lectures to students that are located at the second level.
SISTC requires new Local Area Network (LAN) architecture for these levels along with new applications for multimedia lectures and labs sessions and other network applications. Imagine you are the network manager of SISTC and are required to write a report answering the following questions:
- Draw a network topology using Packet Tracer that represent
- Each level has its own switch that connects all the computers. Each switch can only connect 20 computers, hence, with a total of 75 computers on level 2, it will require a total of 4 switches. These 4 switches are connected to another core switch at the second level.
- Each PC is connected via Straight-through cable with the switch.
- There are two core switches; switch-1 connects level one and level two switches, switch-2 connects level three and level four switches. These switches are connected via Cross-over cables.
- There is one main switch that connects the two core switches (as described above in “C”) via Cross-over cable.
- Write a paragraph that explains the above topology, additionally, the report must be accompanied with the screenshot of the topology from Packet Tracer.
- Staff and students in the SISTC building would like to use the internet. What device would SISTC needs for this purpose? This device will work on which layer (s) of the TCP/IP model? Briefly explain your answer. Where would you place this device in the topology diagram of Question 1?. Take screenshot of the device placement from Packet Tracer and provide it in your report.
- This LAN of SISTC requires both wired and wireless connectivity. Provide a comparative analysis of the appropriateness of different media types which may be used to enable network connectivity. Discuss different types of media suitable for the above scenario with illustrations. Comparative analysis must be recommended in terms of speed, cost, and security (use table for comparison).
- List any 5 network applications (e.g., Web Browser, Outlook etc) that will be used by SISTC and answer the following questions.
- Which application layer protocol does each application use?
- Which transport layer protocol does a specific application use i.e., indicate either TCP, UDP?
- For each of the applications, write their Quality-of-Service (QoS) requirements, in terms of Packet loss, throughput, and delay (time sensitivity).
- Sam (student of SISTC) is sitting at level 2 of the SISTC building. He writes “www.google.com” in his web browser and presses enter. List and briefly explain the application layer and transport layer protocols that will be used by Sam’s machine to download this webpage.
- Robert (lecturer at SISTC) sitting in his office at the fourth level of SISTC building would like to download a file from a Microsoft server, which resides in London, England. Explain how Robert’s request is fulfilled by showing the packet format at each layer of the TCP/IP model. You must briefly explain the encapsulation and de- encapsulation process at both Roberts machine and at the Microsoft server.

5. Submission
- The assignment is to be submitted via the Assignment 1 submission link in LMS.
6. Reference
- You need to provide references in APA format, if necessary.
7. General Assessment Requirement
- Incomprehensible submissions
Assessments provide the opportunity for students to demonstrate their knowledge and skills to achieve the required standard. To do this, assessment responses need to be both clear and easy to understand. If not, SISTC cannot determine that students have demonstrated their knowledge and skills. Assessments will, therefore, be marked accordingly including the potential for 0 (zero) marks where relevant.
