Learning Outcomes (English) This course aims to equip students with a comprehensive understanding of computer networks and the Internet, covering fundamental principles and architectural concepts. Students will learn about basic network performance metrics, exploring the intricacies of packet and circuit switching, and gaining insights into the various protocol layers and service models that underpin network communication. Furthermore, the course delves into the application layer of networking, where students will become familiar with protocols like HTTP and FTP, while also exploring concepts such as web caching and cookies. Moreover, students will gain knowledge of email protocols (SMTP), DNS, Peer-to-Peer file sharing mechanisms, and streaming video protocols like DASH, used in popular platforms such as Netflix and YouTube. In the multimedia networking part, students will explore the intricacies of multimedia network applications, including UDP and HTTP streaming protocols. They will understand the principles of Voice over IP (VoIP) and become acquainted with SIP and RTP protocols. Additionally, they will learn about multiple service classes, integrated/differentiated services, Quality of Service (QoS) and Quality of Experience (QoE) principles, and the Resource Reservation Protocol (RSVP).
