Summary of Content

This module seeks to develop a clear understanding of underlying architectures and systems used to support computer system functionality; introducing the fundamental aspects of networking technologies and the Internet. It will introduce students to the foundations of computer networks, including: Internet architecture, network technologies and protocols (e.g., 802.*, TCP/IP, HTTP), some routing algorithms and policies, network applications, emerging network technologies, virtual private networks (VPN), geographic information system (GIS), and network security. It uses the OSI and TCP layered model to examine the principles and interactions of protocols and services at the application, presentation, transport, network, data-link and physical layers with an emphasis on Ethernet LAN technology. Students will gain practical experience in the investigation of Internetworks in a programme of laboratory work and tutorial study, including exposure to relevant case studies.

Syllabus

Computer Systems Architecture Introduction to computer systems architecture. Data representation and manipulation. The architectural building blocks of a CPU. Organisation and performance of the memory/storage hierarchy. Operating Systems Organisation, structure and basic operation. Computer networks Principles of communications and how networks have changed our lives. Introduction to the concepts of networks, data, local area networks (LANs), wide area networks (WANs), quality of service (QoS), and security issues. Focus on how networks are modelled using the OSI and TCP/IP models and the process of data encapsulation. The Application layer: Explore the interaction of protocols, services and applications with a focus on HTTP, DNS, SMTP/POP, Telnet and FTP. The Transport layer: Focus on how TCP and UDP protocols apply to the common applications. The Network layer: through the examination of concepts related to network addressing, routing, path determination, data packets and the IP protocol. The Data link layer and the protocols associated with it. The Physical layer as well as the standards and protocols that manage the transmission of data across local media. Examine the characteristics and operation of Ethernet as it has evolved from a shared media, contention-based data communications technology to today's high bandwidth, full-duplex technology. Virtual Private Networks (VPN) Principles of communication security and how to secure communications links. Introduction to IPsec and VPN: Explore basic concept and technologies. VPN architectures, topologies and solutions. Mobile Connectivity Architectures, technologies and basic operation associated with Mobile connectivity. Content Delivery Networks (CDN) Investigate basic concept to CDN architectures and technologies. Study various content networking techniques and basic operation. Discuss CDN trends. Network Security Study the principles of Cryptography. Symmetric-Key and Public-Key algorithms: Focus on implementation and basic operation. Management of Public Keys: Certificates Authorities, Digital Certificates, Public Key Infrastructure (PKI). Introduction to Firewall technologies: Explore the different types of firewalls, architectures and basic operation. Intrusion Detection and Prevention Systems: Focus on architectures and real-world implementation. Geographic Information System (GIS) Introduction to GIS fundamentals and spatial analysis. Introduction to Remote Sensing. Introduction to Global Positioning Systems (GPS). Case Study System Introduction to the case study system Case study requirements Demonstration of fully operational case study system

Teaching / Learning Strategy

The course material will be introduced through lectures, while practical exercises, based on the lecture material, will be given to students for their laboratory sessions. Tutorials will be used to help explain and elaborate on both the lecture material and the laboratory exercises. The practical work and coursework will be based around the integrating case study.
