distributed-system-hw

This is a semestral work for MI-DSV course at CTU FIT

It is a simple distributed system that mainatains a shared variable.

• Uses leader election
  • Chang-Roberts election algorithm
• Uses unidirectional ring topology
  • Each node knows about one neighbour
  • Nodes can join and leave the ring
  • Topology is resistent to one simultaneous node fail
  • Heartbeat messages are used to detect failed nodes
• Uses Lamport's clock
  • Log messages have logical clock timestamp
• Written in Golang
• Uses GoRPC for message sending

Run 5 node cluster using Vagrant like this:

1. Compile the project with make build
2. Create 5 virtual machines with vagrant up
3. For each machine (dsv1, dsv2, dsv3, dsv4, dsv5):
   • Connect to machine with vagrant ssh dsvX
   • Run with make dsvX
