Aims
This course unit aims to build on the ideas gained in the first year course unit Fundamentals of Distributed Systems. It aims to provide students with an understanding of the techniques that networking protocols use to achieve error detection and recovery, multiplexing and security protection. To also seeks to show students how the limitations of communication media can limit what applications can achieve. Equipment with the skills needed to go out and setup networks in small and medium sized organisations.
Overview
In today’s connected world, phones, PDAs, computers, .. all share information. In reality, it’s the applications running on these devices, e.g. picture messaging and e-Commerce, that share the information. This course unit examines the principles involved in making this sharing possible, efficient and secure. In particular, it looks at how networking can mask many of the imperfections of interconnection technologies from applications; allow applications to share communication mediums; and potentially give Quality of Service (QoS) guarantees to applications. At the end of the unit you’ll appreciate how different applications can place different demands on the interconnection infrastructure and conversely how technology can limit the types of application that can be run.
