RingPaxos

Throughput of RingPaxos and other Atomic Broadcast protocols RingPaxos is designed to deliver high-throughput traffic within a cluster of machines. This protocol uses IP-Multicast combined with a ring overlay to achieve the best performance.
It can for example deliver close to 900Mbps to each receiver (independently of their number) in a Gigabit switched network.
For more details refer to Ring Paxos: A High-Throughput Atomic Broadcast Protocol, published in the Proceedings of DSN-2010.

The first prototype of RingPaxos is due to Parisa Jalili Marandi and Nicolas Schiper. The source code here is a complete rewrite by Marco Primi.

libPaxos

A C library to be linked by any application. Atomic broadcast is provided by means of a simple submit/deliver interface.
Although the Paxos protocol guarantees safety despite the number of failures, this version assumes that processes do no crash. Some benchmark results are available here (pdf 500kb).

ErlangPaxos

A Paxos algorithm "simulator" implemented in Erlang. Useful for observing the runtime behavior of the protocol and play around with some parameters (e.g. inject failures and packet loss).
Two versions of ErlangPaxos are available, Simple implements the basic protocol, Fast adds different optimizations (it is not an implementation of FastPaxos).
