The internet has evolved to become a central component of society's core infrastructure, almost as indispensible as water or electricity, and even more complex. Like these more traditional networks, the internet is a network of networks, whose behaviour encompasses a huge range of scales both spatial and temporal, and its smooth operation is threatened by bottlenecks, storage problems, flow rate imbalances and variable response times, as well as attacks. This subject looks at the core science and technology underpinnings of the internet. Its goal is to enable an understanding of how the omnipresent network really operates 'end to end'. As such the coverage is broad and fast, covering topics across the protocol stack from the physical layer (including modern wireless access communications), the link layer (including the ubiquitous ethernet), the core TCP/IP/ICMP internet protocols, and the essential addressing schemes and routing protocols. The weekly sessions combine face-to-face tutorials with assessable online quizzes to progressively test the knowledge gained as well as practical data-driven software laboratories and a quiz-like online examination.
