Learning outcomes |
The aim of the course is to provide students with a broad perspective on the state of the art of overlay
communication networks and to provide students with skills to identify open problems and to conduct
research in this area. At the end of the course the student should be able to characterize the state of the art
and know the boundaries of knowledge on some topics of overlay communication networks, should be able
to identify open problems in the field and be able to formulate possible solutions to those problems.

Syllabus |
Overview of overlay communication networks: content distribution networks, Virtual Private Networks
(VPN), peer-to-peer (P2P) systems, anonymous communication, and emerging applications. Peer-to-peer
filesharing: a general perspective on the evolution of P2P traffic worldwide, unstructured peer-to-peer
systems, search methods, structure addition to unstructured systems, Distributed Hash Tables (DHT),
structured peer-to-peer, P2P systems performance. Peer-to-Peer media streaming: streaming applications
based on overlay topologies, IP multicast versus multicast overlay. Security aspects in overlay communication networks: security and privacy, anonymous communication systems (Tor (online
anonymity), Invisible Internet Project (I2P), others), detection and classification of encrypted traffic,
blockchains, and crypto-coin transactions
