Computer and communication have merged with each other. This has had a profound influence on the way computer systems are organized. The concept of computer center is now totally obsolete. The model of a single computer serving all of the organization's computational works has been replaced by Grid Computing or Cloud Computing, in which a large number of separate but interconnected computers work together. These systems are called computer networks.
This course offers fundamental knowledge about the design and organization of computer networks.
Our students will learn the following in detail:
(1) Layered architecture of computer network software;
(2) Basic concepts such as packet, frame, addressing, routing, congestion control, QoS, error control, and flow control;
(3) Basic protocols in each layer.

This course covers the basic network-management principles any system
administrators need to know to set up, operate and maintain IP-based networks.
As one of the core courses in the computer network field, this course provides
students details of layer-3 networking
principles and protocols necessary to understand the operation of the
IP-based networks. Students are asked to set up various small IP networks using real routers.
Network management consists of five main areas, namely fault
management, configuration management, accounting management,
performance management and security management. The goal of this
course is to let the students acquire basic skills of how to configure
and maintain computers, switches and routers in LAN and Internet.
Mastering the concept of IP addressing and routing is central to this goal.
This course consists of lectures and hands-on exercise. Each student
will be required to work with real routers and performs some basic
internet management tasks.
Course material is available on the web page (see below).

Optical networks play a very important role in today's communication networks, not only in the backbone but also in the access networks to the customers. To understand the basic principles as well as advance technologies that enable the optical networks is a must for computer science engineers, a network engineer in particular.
