The course is focused on technologies that support distributed computing: on mechanisms ensuring reliable, efficient and secure connection of application processes, programming interfaces of communication channels and up-to-date middleware technologies. A significant part of lectures is dedicated to distributed algorithms that assure causality, exclusive access, deadlock detection/avoidance, fault-tolerance, mobile computing, and security.

Basic knowledge in the area of computer networks and communication. Basic knowledge of Java programming language.

After passing the course, students will have an overview in the field of distributed systems. They will be aware of the limitations and advantages related to the deployment of such systems. They will also be able to design and implement a simple distributed system.

1. Distributed computation, graph algorithms (Dijkstra), synchronous and asynchronous model
2. Communication system - protocols, routing
3. A synchronous and asynchronous message passing, multicasting
4. Procedural communication - IDL interface, call semantics, asynchronous mechanisms
5. Models of distributed computing - client-server, peer-to-peer, publish-subscribe, cloud computing
6. Support for distributed applications - Java RMI, JMS, Jini; SOAP, REST
7. Time in distributed systems - physical clock synchronization, scalar and vector logical clocks
8. Sharing of resources, distributed algorithms of mutual exclusion
9. Leader election algorithms
10. Termination detection, deadlock - detection and avoidance
11. Replication of data and processes, ensuring consistency
12. Large scale distributed systems: Architecture and computations (DHT, CDN, MapReduce, PageRank, social networks)
13. Mobility in distributed systems - load balancing, mobile agents, cooperative ad-hoc systems
14. Security in distributed systems - Kerberos, PKI, PGP
