COMP2001J Computer Networks

Academic Year 2023/2024

This module introduces key topics of the existing Internet infrastructure. Some topics are cross-layers such as packet-switching, performance measurements, network protocol designs, and network security. Others are layer-specific, for example, network caching in the application layer, reliable transmission in the transport layer, routing and forwarding in the network layer, and multi-access control in the data link layer. Those topics will be discussed with the case studies of popular protocols such as HTTP2, DNS, TCP/UDP, QUIC, OSPF, BGP, ARP, Ethernet etc. Students will also use simulators and packet analysers to study how these protocols work in systematic and realistic settings.

Learning Outcomes:

On the completion of this module, students should be able to:
- understand the architecture of the Internet;
- compare the packet-switching and circuit-switching;
- assess the performance of a computer network system using known metrics;
- explain the motivations and the flow of important network protocols;
- explain the existing mechanisms for key computer network topics such as reliable data transmission and congestion control;
- use network simulators and packet analysers to create a required network scenario, then interpret how the existing network protocol works in realistic settings.
