A project for Distributed Systems course at NTUA, ECE, academic year 2020-2021.
We implemented ToyChord, a simple version of Chord, as discribed in Stoica, Ion, et al. "Chord: A scalable peer-to-peer lookup service for internet applications." ACM SIGCOMM Computer Communication Review 31.4 (2001): 149-160)..
Our application is a file sharing application with a lot distributed nodes DHT. Every node can interact with Chord either as a server, or as a client. The nodes keep information in key-value pairs, where the key is the title of each song saved in the Chord and the value is the node that has this song. Replication is supported with two types of consistency, linearizability (chain replication) and eventual.
Project's assignement and report are written in greek, because this is the main language of this course.

python3 Bootstrap_node.py bootstrap_ip:port bootstrap_ip:port number_of_replicas type_of_consistency
For example:
python 3 Bootstrap_node.py server1:5000 server1:5000 3 eventual
Will fire up bootstrap node in host server1 and port 5000. Chord will keep 3 replicas and the consistency type will be eventual.
python3 Normal_node.py node_ip:port bootstrap_ip:port
For example:
python3 Normal_node.py server2:5000 server1:5000
Will fire up a normal node in host server2 port 5000, that communicates with boostrap in host server1 port 5000.
python3 cli.py --help
This will provide a description of all supported commands by our cli.
Note: It is important to change the bootstrap ip in common_function.py and cli.py to bootstrap_ip:port of your system!
Project is implemented in Python 3.8.5
