This course focuses on basic concepts underlying the design, implementation, and management of distributed systems. It covers fundamental topics in distributed systems, including but not limited to distributed system architectures, inter-process communication, distributed middleware, synchronization and coordination,  distributed agreement, concurrency control, replication, and fault tolerance.


CS 571 (Operating Systems).  NOTE: Prerequisites will be enforced strictly.


The textbook for this class is  Andrew Tannenbaum and Maarten van Steen, ``Distributed Systems: Paradigms and Principles'', Prentice-Hall, 3rd edition, version 3.01, 2017.  Additionally, the following books may be used as reference texts.

  1.  G. Coulouris, J. Dollimore, T. Kindberg, “Distributed Systems: Concepts and Design,” 5th Edition, Addison-Wesley, 2012.
  2.   K. Birman, "Reliable Distributed Systems: Technologies, Web Services and Applications,"  Springer Verlag, 2009.

Academic Integrity

You are expected to abide by the University's honor code and the CS Department's Honor Code and Academic Integrity Policies during the semester, i.e., collaboration between students in different groups on an assignment is unacceptable. Any violation of the honor code will result in referral to the honor council.

NOTE: I will be using tools, e.g., MOSS , to detect plagiarism in the programming assignments.
