# Chordy - a distributed hash table

In this homework assignment you are required to implement a distributed hash table following the Chord scheme. In order to understand what you're about to do you should have a basic understanding of Chord and preferably have read the original paper.

The task is to implement the distributed hash table up to the point where you have added the store and done some smaller experiments (section 1 and 2). Write up your results and experience in a report and hand it in at the corresponding reporting seminar.

Some code that might come in handy when testing the system.

At the corresponding reporting seminar you are required to present and demonstrate results of your homework, discuss your findings and problems (if any) you have faced, pros and cons of your solution, and your suggestions on how it can be improved. Specifically for this homework, be prepared to build a small ring (dht) and discuss how to handle possible failures.

At the seminar we will build a larger ring and perform some measurements. We will also discuss how to proceed with handling of failures.

Regarding the first version of chordy (section 1):

at the end on page 4, in the stabilize clause, i think it should say:

node(Id, Predecessor, Successor);

node(Id, Predecessor, Successor, Store);

You're so right, fixed.
