fantoch: framework for evaluating (planet-scale) consensus protocols

Protocols currently implemented

• EPaxos: (source)
• FPaxos, and thus Paxos as a special case: (source)
  • implemented following Paxos Made Moderately Complex, which enables a certain degree of parallelism at the leader
• Caesar: (source)
• Atlas: (source)
• Newt: (source)

What does it do?

• all protocols implement the Protocol trait
• this specification can then be used for
  • simulating the expected latency in a given geo-distributed scenario (infinite CPU is assumed)
  • running the protocols in a real setting
  • (model checking is coming soon!)
• this is achieved by providing a "simulator" and a "runner" that are protocol-agnostic and are only aware of the Protocol (and Executor) trait
