The course trains the student in WAN technologies that enable the interconnection of networks at a global level, backbone networks and access networks, as well as in the design of global networks within fully heterogeneous environments with the application of Quality of Service (QoS) technologies that allow the integration of all types of services.

It is recommended to have completed Local Area Networks (49063 / 49A63).
The course aims to provide the student with a solid foundation in the fundamentals of transport and access networks, developing the ability to understand their characteristics, protocols, interfaces and operating criteria within the field of telematic networks. Likewise, it seeks to promote the understanding of Quality of Service principles and their application to different types of traffic, as well as the development of competences for the analysis, configuration, administration and troubleshooting of networks, contributing to the technical training required for professional practice in the field of engineering and information and communication technologies.

9. SD-WAN
- Definition
- Application example
The course combines the following teaching methodologies: lectures, exercises and classroom activities, and practical sessions.
It has two relevant training activities:
- The exercises carried out in class. As the syllabus progresses, exercises are carried out in which the concepts studied in class are applied in a practical way to network design and configuration scenarios.
- Practical sessions: In these, the student implements real network interconnection scenarios in a “cloud” environment.
The Final Grade (FG) is calculated as follows:
- Continuous assessment (AC): 40%
- Class exercises: 20% of AC
- Practical sessions: 40% of AC
- Checkpoint Exam: 40% of AC
- Ordinary Exam (February) / Extraordinary Exam (July): 60% (Entire syllabus)
Final Grade (FG) = Max(Exam (100%), AC (40%) + Exam (60%))
The course will be successfully passed if FG >= 5.
The following will be assessed:
- The understanding of the fundamental concepts related to transport and access networks, as well as the associated main protocols and interfaces.
- The ability to analyse and differentiate the essential elements of telematic networks according to their function, characteristics and fields of application.
- The understanding of the concept of Quality of Service and its application to the different types of network traffic, such as voice, data and video.
- Knowledge of the basic principles of routing, as well as the elementary criteria for network planning and sizing.
- Correctness in the basic configuration and administration of telematic networks in accordance with the technical requirements set out.
- Conceptual and terminological rigour in the use of the language specific to networks and communications.
- Clarity, coherence and correctness in the presentation and justification of the proposed answers, procedures and solutions.
- Course notes.
