Data Networks (5 cr)

Evaluation scale

0-5

Objective

You learn the structure, protocols of data networks used by computers (and other end devices). You also know the principles of planning a data network.

You are familiar with protocols and data transmission principles used on the Internet. You know the layers of the OSI model and identify the technologies and protocols used on each layer of the model. You can design a local area network using switches, routers, workstations, and servers. You are able to design cabling, switching topology, and routing scheme to run the data network. You know the different devices used on a network (e.g. switches, routers, firewalls, wireless base stations). You can change, handle and save the configuration used in network devices. You know how local area networks interconnect to one another through wide area networks.

EUR-ACE Knowledge and understanding
You know the main modeling methods of data networks and you have knowledge and understanding of data networks and their effects. You know the basic principles of network design and how to configure network devices.

EUR-ACE Engineering practice
You can apply data network skills to communication between devices.

Content

In this course, you will learn the principles of network structure and protocol design, as well as the principles of Internet communication. You will master the layers of the OSI model and be able to design and implement local area networks using switches, routers and servers. You will learn how to design cabling and routing plans and how to handle network equipment configurations. You will also understand how to efficiently connect local area networks to backbone networks.

The contents stated through the OSI model:

Layer 1
Physical cabling (copper, fiber)
Wireless Local Area Networks
Basic modulations in data transfer
Devices

Layer 2
Ethernet switching
Network Segmentation (VLANs)
Loop detection (Spanning Tree)
MAC addressing

Layer 3
IPv4 and IPv6 addressing, subnetting
Routing (Static, OSPF and BGP)
DHCP, ARP

Layer 4
TCP and UDP

Layers 5 to 7
SSH, HTTP, DNS, SMTP

In addition, best practices in network design and configuration management are covered in the course.
