This is a project done during the course Distributed Systems Development taken at ESCOM - IPN. The purpose of this project was to learn how to design and implement a Distributed System in C++ language, coding an entire Object Oriented library from raw sockets up to a web page where the final user could see the results. Take a deeper insight into the system here.
Design and implement a prototype of a distributed system to tackle down the problem of register, store and show in a web page the statistics of the votes received from a fictional text messaging service (SMS) national server.
- C++
- C
- Javascript
- Materialize
- HTML 5
- CSS
- User Datagram Protocol (UDP)
-
Taking note of the Request-Reply Protocol described in "Distributed Systems" by George Colouris 5 Edition Chapter 5 implement a reliable version (against packet loss), Object Oriented approach and adapt it according to the project needs using the User Datagram Protocol (UDP).
-
The System must acknowledge each vote received by sending back a message with an unique timestamp including the exact moment in which the vote was stored in the server.
-
The System has to check whether a vote was already been done. This must be accomplished by maintaining a TRIE data structure which has a record of all cellphones that had already participated.
-
Because it is a distributed system use 3 servers to do all the task. This involves having a balance and a communication mechanism among the servers.
-
Last, the system must have a web interface i.e. a web page in which the administrators can check the statistics about all the votes registered in real time. This involves that each of the servers will have a web server embedded, use Mongoose for this task.
