General description

"What concepts and underlying technologies allow the Internet to operate correctly and efficiently?". As computer engineers, this is the basic question that we aim to respond in this course. To that end, we study the TCP/IP network architecture, which has lasted for more than thirty years and has provided "scalable connectivity" to more than 1800 million hosts spread all over the world -more than half of them are mobile hosts. This course offers a general perspective on computer networks, starting with a broad introduction to the discipline emphasizing architecture and performance. Next, we study the physical and datalink layers (TCP/IP layer 1), LAN switching, IP forwarding and routing, the global structure of Internet and, last, the TCP and UDP transport protocols. The core resource for the course is the textbook "Computer Networks: A Systems Approach" and the laboratory "Practical Exercises on Computer Networks", written by the lecturer and which goal consists of developing the students' intuition in a field so vast as computer networks.

Students will develop the ability to design small wired and wireless VLAN-based internetworks which includes the ability to plan and implement an IPv4/v6 numbering and addressing plan, design and define the internetwork's architecture based on IP routers and simulate the network operation. Students will be able to make sensible decisions regarding the use of technologies such as NAT/PAT, DHCP, DMZs, etc. The internetwork will be implemented upon real equipment and the functional and performance requirements will be properly established by using real traffic traces and a network analyzer, in the end, the students will be able to devise relevant experiments with the intention of adapting the design after the aforementioned feedback has been retrieved.	A8400 A8401 A8404 A8405 A8406 A8407 A8432 A8434 A8518 A8520 A8542 A8611 A8626	C5
Students will develop the ability to devise experiments with real equipment and real traffic patterns synthesized by their own network programs. These experiments will be aimed towards establishing the internetwork stability and its basic bandwidth, throughput and delay performance measures. These experiments are also aimed towards developing the student's intuition about the best effort model, reliable and non-reliable transmission. In the end, students will be able to manage a presentation and discussion session to the class.	A8400 A8401 A8404 A8405 A8406 A8432 A8434 A8518 A8520 A8542 A8583 A8602 A8611 A8626

Methodologies

Methodologies ::

	Description
Laboratory practicals	Design and implementation of experiments with real traffic and equipment in a data-communication specific laboratory
Problem solving, classroom exercises	Chalkboard network design and performance calculation problem solving. The objective of these sessions consists of exposing the student to simple, specific and example based problem resolution which will play a vital role in streamlining their mastery and understanding of the same problems ina laboratory setting.
Assignments	The objective of these sessions consists of exposing the student to simple, specific and example based problem resolution which will play a vital role in streamlining their mastery and understanding of the same problems ina laboratory setting.
Presentations / expositions	These sessions are directed toward helping the student to develop their writing and communication skills about advanced computer networking topics which somewhat lay outside the scope of the course and, nevertheless, it is convenient for them being able to convey the knowledge even though they are not fully competent on it.
Practicals using information and communication technologies (ICTs) in computer rooms	In these sessions the student will get hands on experience in configuring computers and basic network equipment, will use a network simulator and write a simple C/S Java/C application. These abilities will contribute to the student being able to develop a subtantial piece of software in a progressive, gradual manner.
Personal tuition	Lecturer's office hours.
Lecture	Detailed explanations of the functions, structures ald essential algorithms on which many computer network features are based. Lectures will summarize the essential aspects of each chapter and provide students with guidance as to how to approach their study.

Personalized attention

Personal tuition

Description

Students may request personal and group tutorial sessions on an ongoing basis as the semester develops. Also, office hours are scheduled on a weekly-basis on the course Google calendar

Assessment

	Description	Qualification
Mixed tests	In-lab progress-report practical exam. Students are required to keep up-to-date a LabBook record of the results obtained in each practcial, this LabBook will be required by the intructor to be submmitted several times in the semester.	10%
Practical tests	A single, final submission of a practical work composed of software and documentation. Can only be submitted and assessed in the continuous assessment period. Every submission will be subject to a written exam which must be passed in order for the instructor to evaluate the practical submission.	10%
Extended-answer tests	Two closed-book written exams that consist of test, quiz, short answer and exercise questions. The pass mark is granted on the basis that the student obtained a passing mark in each of two term tests. Every theory and problems test that has not been passed will have to be re-examined in a face to face, closed book written exam in June. Each of the two term exams must be passed so that the final grade is computed.	80%

Other comments and second call
The pass mark is granted on the basis that the student obtained a passing mark in each of two tests. Every theory and problems test that has not been passed will have to be re-examined in a face to face, closed book written exam in June or in July. The laboratory practical work submissions must be submitted on their due date in june only since no other new submission will be planned in July. Each of the two term exams must be passed for the final passing to be computerd. Regular attendance and completion of Lab practicals is a requirement for granting the passing mark.
