Computer Networks

This course studies the standard models for the layered approach to communication between autonomous machines in a network, and the main characteristics of data transmission across various physical link types. It considers how to design networks and protocols for diverse situations, analyses several application and support protocols from a distributed systems viewpoint, and identifies significant problem areas in networked communications. Topics include: communication network architectures, signalling and modulation across physical media, real-world local and wide-area networks, internet protocol fundamentals, performance and monitoring of networks, routing, network security, and application protocols for distributed systems including web, email, video, internet-of-everything and other contemporary network topics.
