Final exam
Details
In a final examination (oral, optionally written), the students demonstrate their competences in summary form. The examination comprises the following sections, in which six taxonomy levels are included (reproducing, understanding, applying, analysing, synthesising, and evaluating).
1.) A good understanding of basic terminology, concepts and techniques.
2.) Application of planning and evaluation techniques.
3.) Evaluation of proposed solutions for correctness, identification of errors in statements or given networks.
Minimum standard
Achievement of the individual minimum score per exam, typically 50% of maximum score.

Learning goals
Knowledge
Achive basic understanding and implementation knowledge on Next Generation Network (NGN) defintion by ITU-T, IP Multimedia Subsystem by 3GPP, and ETSI, and Next Generation Internet (NGI) definition by IETF, ITU-T standards, Multimedia Services in NGN, VoIP, Video-over-IP, RTP encaplsulation, Service Signaling, SIP protocol, SIP Digest Authentication, SDP service description and capabilities, SIP servers, Session Border Controller (SBC), SIP Gateway Technologies, SIP routing, NAT Gateways, NAT solution, SRR, STUN , TURN, IMS in mobile networks, IMS in fixed-line networks, VoIP in enterprise networks. IMS in virtualized core network.
Skills
Students evaluate requirements for NGN services and plan, implement and analyze NGN services based on SIP signalling or alternative signalling protocols. They are competent in functional analysis and troubleshooting by deep packet inspection (DPI) protocol analysis. They evaluate the performance of NGN services in terms of timing, throughput, latency and delays, jitter, robustness in case of packet errors, and security aspects.

Learning goals
Knowledge
Naming, structuring and classifying concepts and technologies for NGNs or NGIs. Demonstrate network analysis techniques and tools, know methods for NGN services and network planning.
Skills
Working on a small project in a tiny team (2-3 team members) on actual technologies in the area of NGN services and NGI services.
Set-up an NGN/NGI environment and NGN service, including planning, implementation and evaluation of security aspects and protocol anlaysis plus performance evaluation.
The results are reviewed during the course period, summarised in a report and presented to the class. Individual project proposals by students are wellcome.
