COMP2207 Distributed Systems and Networks
Module Overview
The networking aspect of this module will expose students to the principles of layered communication protocols, the architecture of the Internet, and the principles of how the components of the TCP/IP layered model are designed and operate. The distributed systems aspect will focus on distributed algorithms, but include distributed communication and transaction models, distributed objects (including Java RMI), web services and peer-to-peer systems. Students should gain a clear understanding of the technologies covered in terms of the underlying fundamental principles.
Aims and Objectives
Module Aims
The aims of this module are two-fold: to teach the theory and practice of concurrent and distributed systems, and to provide a solid grounding in the fundamentals of all major aspects of computer network technology.
