Teaching Material

This course will deal with the fundamental issues in large distributed systems which are motivated by the computer networking and distribution of processors, and control. The theory, design, specification, implementation, and performance large systems will be discussed. Concurrency, Consistency, Integrity, Reliability, Privacy, and Security in distributed systems will be included.

A special feature of the course includes interesting problems in Mobile Ad hoc networks and Cloud Computing that can benefit from research ideas in distributed systems. Research related to Mobile Computing, Streaming databases, Video conferencing, Peer to Peer systems, Cloud computing will be covered.

b)    Distributed control for synchronization and concurrency (will include the models for concurrent processing and transactions, theory of serializability, classes of concurrency control approaches, performance evaluation of these classes, centralized control vs. decentralized control).........(12 Hrs.)

c)    Distributed commitment/termination (involves preservation of atomicity of transaction execution, blocking/non-blocking protocols).........(6 Hrs.)

d)    Resiliency in distributed systems (involves design of protocols for site failure, network partitioning, loss of messages or variable transmission delays, consistent recovery)..........(3-6 hours.)

e)    Security in distributed systems. (involves study of a variety of attacks on the components of system (such as on routing protocols in ad hoc networks), privacy issues in Peer to Peer systems, trusted collaboration and dissemination of data among cooperative entities).........(9-12 hours)

f)     Design and Implementation of Prototype/commercial systems, Experimental Evaluations. Details of peer to peer system developed at Purdue and several commercial systems .....(9 Hrs)

Assignments and Grading Policy:

The following assignments/exams etc. are planned.

a)    Non programming assignments ....5 (Once every two weeks: 20% of grade)

b)    Programming assignments in the form of a project that you select from a choice of 6-8 projects. You may suggest a project based on your interest. Demonstration of project is scheduled on April 16, 2013. (30% of grade)

c)    Mid Term and Final Exams ....2 (20% of grade each)

d)    Class contributions (e.g., class attendance and participation, discussions, outside reading/presentation of research papers) .... (10% of grade) You should attend all classes for highest class contribution credit.

e)    You can expect a grade of A if you score close to 87% or higher. If you do not do the project or home works or score less than 75%, a C grade is possible.

f)     To pass the qualifier, a grade of high B in class and 75% in qualifier questions is expected.


Your programming projects can involve implementing some component for integrity, security, reliability, or privacy policy. Or communication facility for LAN, or routing in mobile adhoc networks can be developed.


You can conduct experiments on ns2, or peer to peer system prototype, JAVA RMI (I suggest using java and java RMI for communications. If you haven't used RMI, the Hello World tutorial at http://java.sun.com is a good starting point.
