Objetivos

This course covers topics in advanced networking, namely congestion control, quality of service, multimedia networking, peer-to-peer networks, and communication services, like email, web and cloud. The goal is to give students deeper understanding of networking by covering concepts, principles, protocols and services that are not covered in basic computer networking courses. Typical network services, such as email, web, voice over IP or video on demand, are covered focusing on their design principles and evolution.

The student should acquire theoretical and practical knowledge in the fields of communication services, multimedia services and de-centralised services running on top of TCP/IP infrastructure. The course will also cover models for quality of service (QoS) support as well as mechanisms for its implementation in IP networks.

The student should be able to analise requirements of communication services, recognise trade-offs (theoretical and practical) and propose appropriate solutions in terms of protocols and network connectivity. The student should also understand ethical, legal and economical issues related to the availability and deployment of communication services.

Observações Bibliográficas

Support material will consist also of survey papers and books available online. The references to these materials will be made available per topic in the moodle page of the UC.

Métodos de ensino e atividades de aprendizagem

The course is based on lectures, interleaved with example exercises and discussion of relevant networking papers on the covered topics.

Additionally, laboratory assignments aim at solidifying concepts from the lectures with hands-on experience in setting up, debugging and monitoring networking applications and services, as well as offer the opportunity to get acquainted with practical issues related to the services and protocols discussed.

Obtenção de frequência

Distributed component of evaluation D > 50% and delivery of all 5 reports of laboratory assignments.

Fórmula de cálculo da classificação final

The components for student evaluation are:
E – Exam
H – Homework (average of best n-1, n=11)
P – Projects (average of n, n=6)
R – Article reviews (average of n, n=4)

Each component will receive a grading in 0-20 and the final grade will be calculated according to the following rule:

35%*E + 15%*H + 10*R + 40%*P

Passing requires a minimum grade of 50% in each component.

Provas e trabalhos especiais

Each student must participate actively in the laboratory classes and must deliver all reports on the assignments. The majority of the work should be concluded during the lab classes.

Avaliação especial (TE, DA, ...)

Students under special legal provisions will be subject to all evaluation procedures of regular students except the weekly questions, i.e., students must deliver article reviews and project reports. They must do so up to one week before the exam they pretend to write, and the exam will be graded only in case all other evaluation components have been handed-in on time. This shall also apply in cases where the students are allowed to required exceptional exams.

Melhoria de classificação

Students shall be allowed to improve grades upon request in the first exam following the exam they pass.
