Seminar Thursday, 12:15 pm – 01:45 pm, room 04.137 UnivIS

Teilnehmende arbeiten sich selbständig anhand der ausgewählten wissenschaftlichen Literatur in ein vorgeschlagenes Thema aus dem Bereich der Kommunikationssysteme ein, erstellen dazu eine schriftliche Ausarbeitung, bereiten einen Seminarvortrag vor und präsentieren ihn vor Lehrenden, interessierten wissenschaftlichen Mitarbeitern des Instituts und Kommilitonen der Lehrveranstaltung.

Zu den zu erwerbenden Kompetenzen zählen
  • die Literaturrecherche,
  • korrektes Zitieren,
  • die Fähigkeit auszuwählen, welche Aspekte in der Ausarbeitung und im Vortrag behandelt werden,
  • zielgruppengerechtes Schreiben,
  • die Verwendung von Textverarbeitungswerkzeugen für die Präsentation – und die Ausarbeitung,
  • sicheres Auftreten beim Vortragen eines wissenschaftlichen Themas sowie
  • fachspezifische Fragen zum ausgewählten Themengebiet zu beantworten.
Am Ende jeder Lehreinheit
  • stellen die Teilnehmenden gezielt Fragen zum vorgetragenen Thema,
  • diskutieren über fachliche Aspekte der Präsentation,
  • üben konstruktive Kritik an der Darstellung des Themas und
  • bewerten die Präsentation aus vortragstechnischer Sicht.

  • gesammelte Bücher, Artikel und Weblinks zu einem einschlägigen Themengebiet
  • Reinhard German. Allgemeine Hinweise zu Seminarvorträgen und -ausarbeitungen.

Software Defined Networking (SDN) is a paradigm shift in networking to decouple the control plane from the data plane and place the control of the system in a logically centralized node called “SDN controller”. The SDN controller has a view of the entire network and can perform online control actions. Quality-of-Service (QoS) refers to traffic characteristics and requirements such as load, delay, and loss and is important in today and future networking. Traffic engineering (TE) refers to the selection of routing paths through a network in order to satisfy certain conditions, such as low resource utilization or achieving QoS goals, important techniques in this context are constraint-based routing algorithms. With SDN new opportunities have emerged. In this seminar we will first recapitulate some basic principles on the subject and then read and present recent research papers.
