In LANs (Local Area Networks) and WANs (Wide Area Networks), routers and switches are the basic hardware components. Simple network switches have become ever more capable as technology and computing power has increased, so a fundamental knowledge of the basic operations of switches is key to progress for the networking professional. WAN technologies provide connectivity across geographical areas, and are key to extending the reach of networks, and are also integral building block for the Internet as a whole. Though the industry certification is not formally part of this course, students can undertake this course, as it will cover concepts and techniques which are consistent further progress towards the Cisco CCNA industry certification, should they wish to pursue it separately.

The course advances the knowledge of routing and routing protocols, building upon previous knowledge of routing and switching concepts. Virtual LANs, their configuration and deployment, and their interaction with routers are investigated in this course. WAN technologies and their implementation are discussed, as well as the advantages and disadvantages of particular technologies. Students will be using network documentation and troubleshooting methodologies for identifying and solving problems in routed and switched networks.
