Module Description: The role of the internet has evolved from a research collaboration tool to a resource many people use day-to-day for work and entertainment applications. In addition over the years, networks have become more heterogeneous in terms of their technology with an increasing reliance on cloud operations and virtualisation to ensure that the applications are supported with higher reliability and lower latency. As a result of the evolution and complexity of networks, new methods of maintaining and managing networks are required. This module teaches the skills required to manage, debug, and scale modern networks to meet modern demands, and maintain consistent performance and reliable operation. It explores how network administration evolved from device-centric to network-centric, and examines recent developments such as intents, programmable data planes, and formal verification of networks.
Learning Outcomes
On successful completion of this module the learner will be able to:
LO1 Critically evaluate the complexities in managing a complex network and the interaction and correlation between nodes in the network.
LO2 Configure and monitor network devices and automate their management using appropriate tools and approaches.
LO3 Configure, monitor, and troubleshoot complex networks using northbound applications running on top of software-based networks.
LO4 Automate network management using policies and intents and network automation frameworks.
