Inhoud vak

The emphasis in this course is on fundamental concepts in digital communication. In modern computer networks, data communication takes place by sending data from A to B via a layered architecture where each layer implements a different abstraction. The higher layers are responsible for handling web pages, emails, and similar things, that are translated into packets, bits, and eventually digital signals on physical links (e.g., light pulses, electrical signals in copper wires, radio waves).

This layered architecture with increasing levels of abstraction and separation of concerns, is a fundamental approach that you will encounter in all aspects of computer science (and beyond). Within this architecture, we will concern ourselves with questions like: what route should the data follow through the network, what do we do when errors occur, how do we interconnect two networks that have completely different properties, etc.

Following the IEEE/ACM Computer Science curriculum, topics to be discussed include the layered network architecture, different types of networks (e.g., wired and wireless, LAN and WAN), multiplexing, error control, flow control, routing and forwarding, names and addresses, high-level architectures of networked applications (peer-to-peer, client/server, etc), performance issues, and scalability issues. These issues are discussed while exploring the technology behind the Internet and its popular protocols (e.g., TCP, UDP, Ethernet, Wifi, etc.).

Toetsvorm

(Mandatory) Basic lab assignments.
(Mandatory) Final exam
(Optional) Mid-term, multiple choice. The results of the mid-term exam count only if the final exam is also taken by the student, and only if it increases the final grade of the student.
(Optional) Optional lab assignments.
(Optional) Self-study assignment.
(Optional) In-class exercises, oral and written.

All partial results (including the lab, and the mid-term and final exams) are only valid during one academic year.
The end grade is the total number of points accumulated across all assessment possibilities scored divided by 1000.
It is possible to score a perfect 10 as the final grade.

There is only a resit opportunity for the exam.
