Objectives



Acquire sufficient knowledge to take on the following tasks:



• Manage computer network infrastructures (local, corporate campus, data centre, or a corporate network with WAN links).

• Design computer networks.

• Manage teams of technicians responsible for these networks.

• Self-training in any specific area of networked technologies.



Context in the degree course



The subject:

• Deepens and extends the concepts and techniques seen in the ”Introduction to Computer Networks” subject in the 2nd year.

• It complements the “Systems and Networks Administration” subject in the 3rd year.

• It provides a solid basis to the subjects “Komunikazio Mugikorrak eta Multimediakoak”, “Network Design and Projects” and “Security, Performance and Availability of Services and Infrastructures” in the 4th year.



Previous knowledge



To take the course, it is necessary to have knowledge of the content of the subject ”Introduction to Computer Networks” (2nd year). To do this, we recommend not enrolling in “Network Technologies and Infrastructures” if you have not previously passed “Introduction to Computer Networks”.

Contribution to the vocational training of students



• Knowledge of commonly-used technologies in the computer networks around us.

• Practical experience in the use of networked equipment, mainly switches and routers.

• Confidence in oneself when it comes to taking on responsibilities as a network engineer.

==================

Practical credits

==================



Practical credits will be taught in the laboratory using the GNS3 emulator. In general, they will aim at a dual objective: (a) to assist through practice in assimilating and expanding some concepts studied in theoretical sessions, and (b) to exercise in the configuration and management of network equipment.



1. Routing protocols: OSPF, BGP.

2. WAN lines: MPLS, VPN.

3. Local network technologies: Spanning Tree Protocol.

Teaching Methodology



Different teaching methodologies will be followed, using the most suitable one for each area to be worked on or skills to be acquired. In general, autonomous work and personal initiative will be encouraged for the search of information that can complement that provided in class.



Theoretical sessions



Conceptual content in the subject will be introduced by lectures, with the students participating in occasional debates. Problem-solving in class will be done in a participative way. Problems and exercises to be solved will be given individually or in groups in order to facilitate the comprehension and assimilation of the technical concepts presented in class.

As a complement to the theoretical sessions, the faculty will provide, through graduation, readings or exercises for the personal work of the students.

The formulation of questions and open discussion will be encouraged so that the student can acquire skills in oral communication, the ability to summarise and teamwork.



Practical sessions



Practical credits will be developed in the laboratory, on the GNS3 network simulator installed on a Linux virtual machine.

For each laboratory students are provided with a statement and a network topology GNS3 about which to do the experiments and exercises proposed in the statement. The learning activities to be developed in each laboratory include:



1. Network configuration exercises. Students are presented challenges. They have to make the network work properly, making use of the technology object of learning. Its academic objective is for students to acquire skills in network management tasks, while also consolidating knowledge on the technologies studied in theory.



2. Experiments. In them, students must reproduce experimental situations on the provided network, observe its behavior, obtain conclusions, and, in many cases, propose and implement solutions to the detected problems.



3. Research exercises. Challenges are posed to students regarding aspects beyond those exercised in the laboratory, so that they can investigate and put into practice the provided network. These kinds of exercises are for the personal work of the students, to develop outside the laboratory.



Non-classroom work



Apart from the personal work linked to completing the objectives of the specific theoretical and practical sessions, and to the preparation of the corresponding evaluation tests, the students who opt for continuous evaluation should prepare two works outside the school hours, one linked to the theory of the subject (individual) and another to the practical part (group).



The objectives of this work outside school hours are as follows:

- Enhance the participation of students in their own training.

- To be able to delve into theoretical and practical questions little or nothing worked in the classroom sessions.

- Strengthen self-training capacity.

- Improve the capacity to produce written technical reports.

• Continuous Assessment System
• Final Assessment System
• Tools and qualification percentages:
  • The percentages and types of evaluation are specified in subsequent sections (%): 100

Students have to choose between two types of evaluation: continuous or global evaluation.



By default, all students will be considered in continuous evaluation. The step to global evaluation takes some of the following forms:

- Automatic transition to global assessment. It occurs due to lack of class attendance, non-submission to a continuous evaluation test, or non-compliance with deadlines in the delivery of evaluated works continuously.



Students who, having been kept under continuous evaluation want to give up at the last minute, must email the professor, with a deadline of one week before the last written evaluation test. If they did not, and did not attend to that last test, their note will be calculated by measuring that test with zero points.



Overall assessment



For the overall evaluation, the students must perform a written examination where the weight of the theory is 60% and that of the practical part is 40%. The final rating shall be obtained from the average of the ratings of the two parties with a minimum rating of 3.5 required for each. To approve the subject, a minimum final grade of 5 must be obtained.



Failure to take the written test of the global evaluation will be considered as a resignation from the evaluation.

The extraordinary call will be the same as the overall evaluation of the ordinary call, that is, by means of a written examination where the weight of the theory is 60% and that of the practical part is 40%. The final rating will be obtained from the average of the ratings obtained in the two parts, but a minimum rating of 3.5 is required for each part. To approve the subject, a minimum final grade of 5 must be obtained.



Those who have presented in an ordinary call and, having suspended the subject, have approved one of their two parts (theory and practice), will be kept the note obtained in the approved part, so that they will only be evaluated in an extraordinary call of the suspended party. If you do not want to keep that note, in order to qualify for a better qualification, you must communicate that decision to the faculty, by email and not later than one week before the date of the test.



In order to renounce the call, it is sufficient not to attend to the final examination.
