The objective of the course “Applications and Services in Internet” is to teach the students some of the preliminary concepts in networking, network pricing and how the content delivery and the de-facto video streaming systems work in the Internet. Through some beginning sessions, students become familiar with some of the fundamental concepts in computer networking and wireless communications, auction-based network pricing strategies, quantifying the factors that impact the quality of service (QoS) in data delivery as well as identifying the criterias which impact the perceived quality of experience (QoE) of video streaming mobile users. The discussions are then followed by learning how and with which mechanisms the content delivery networks (CDNs) forward the clients request in the Internet. The structure and the ways that video streaming systems work in the Internet are then taught by the course. Some new topics in live and interactive video streaming are also covered. In addition to the live sessions, the course also consists of multiple online sessions which are in the form of recorded videos. Online sessions are related to the assignments and students should watch them according to the scheduling. There are four assignments which students should perform in groups of two people and deliver the report of their experimental results. The evaluation is performed based on the quality and depth-analysis of the conducted experiments.
