Introduction

The contents of this course are distributed services implemented on the higher layers of the ISO/OSI stack, with a special focus on the application layer. After covering the basic features of distributed applications, the largest part of the course will be centered on peer-to-peer (p2p) architectures.

The course will teach the architecture, principles, mechanisms and functionalities of P2P search and content distribution overlays, explaining in detail unstructured and structured overlays, DHTs, file-sharing and video streaming, while giving an in-depth view on popular applications like BitTorrent, eDonkey, Kademlia, etc.

To round out the offered knowledge, other examples/protocols for distributed services, such as remote procedure calls, web services or some directory services will also be discussed. While for this type of service, the degree of distribution is lower, they serve to illustrate architectures with application logic on networked machines, and will give the student an overview over current techniques to implement distributed applications.
