This unit aims to introduce the systematic top-down network design approach for designing enterprise computer networks. A top down process focuses on requirements analysis and architecture design, which should be completed before the selection of specific network components. The unit provides students with tested processes and tools to help them understand traffic flow, communication protocol behaviour, and internetworking technologies. On completion of the unit, students are equipped to design enterprise computer networks that meet an enterprise users requirements for functionality, capacity, performance, availability, scalability, affordability, security, and manageability.
At the completion of this unit, students should be able to:
- select and apply major protocols used in computer networks for the design of LAN, WAN and WLAN systems;
- analyse and resolve all issues in implementing the selected protocols at LAN, WAN and WLAN designs;
- apply the detailed knowledge and understanding of secure network architectures for the design and implementation of firewalls;
- demonstrate the ability to incorporate the latest developments in TCP/IP protocols (e.g. IPv6, IPSec, multicasting, VoIP, QoS, iSCSI) into network design;
- apply the knowledge and skills gained to implement and manage TCP/IP services within wired and wireless LANs;
- exhibit the ability to use network performance evaluation tools, network packet analysers, and other performance measurement tools;
- demonstrate the ability to use simulation packages to construct models of computer networks;
- analyse the use of models for performance measures and performance prediction of advanced data networks;
- demonstrate practical ability to design and setup LANs, WANs, and wireless LANs using standard protocols and typical hardware;
- make recommendations for network performance improvements;
- demonstrate practical skills in setting up TCP/IP connections and routing configurations for different environments;
- demonstrate the ability to fully document the design for future reference and upgrade.
