Communication Technology 2 (DAT300)

This course builds and expands on the contents of DAT230 Communication Technology 1. Key topics include LAN/WAN switching and routing protocols, WLANs, quality of service, and recent advancements in computer networking - e.g., IoT, cloud-based and software-defined networking. The completion of this course together with DAT230 and additional independent studies provides the student with the necessary skills to obtain the Cisco CCNA certification.

NB! This is an elective course and may be cancelled if fewer than 10 students are enrolled by August 20th.

The course builds and expands on DAT230 Communication Technology 1. It provides a detailed overview of how Local Area Networks (LANs) are configured and scaled by utilizing modern switching and routing technologies. In doing so, it discusses multiple dynamic routing protocols (e.g., OSPF). Further, it provides an overview of Wide Area Networks (WAN) technologies and protocols with a focus on encapsulation, tunnelling and routing protocols for branch and P2P connections over WANs (e.g., VPN, BGP, GRE, IPSec and MPLS) and will also briefly overview general aspects of network security and monitoring in such environments. Further, Quality of Service (QoS) in the network will be discussed. This will include discussion of QoS strategies at different network stack layers e.g., AQM and queueing strategies, Diffserv and Intserv. In addition, ACLs and will be discussed.

In the latter part of the course, the state-of-the-art networking trends and evolution of communication networks (and Internet technologies) at multiple layers of the networking stack will be discussed. Among other things, this will include the latest trends on network softwarization and virtualization concepts using SDN and NFV in the cloud and network edge environments.

It is worth noting that the course curriculum comprises of both lecture and lab sessions. The completion of this course together with DAT230 and additional independent studies provides the student with the necessary skills to obtain the Cisco CCNA certification.

Learning outcome

Course assessment

There must be an early dialogue between the course supervisor, the student union representative and the students. The purpose is feedback from the students for changes and adjustments in the course for the current semester.In addition, a digital subject evaluation must be carried out at least every three years. Its purpose is to gather the students experiences with the course.
