Simple implementation of the Mutual exclusion within ring topology(Ping-Pong) algorithm. It uses ZeroMQ for the network communication.

Make sure that ZeroMQ is installed in you system (version >= 4.0.1).

dep ensure
make build

./bin/ping-pong (flags) [node_addr:port] [next_node_addr:port]

example:

./bin/ping-pong 127.0.0.1:8880 127.0.0.1:8881
./bin/ping-pong 127.0.0.1:8881 127.0.0.1:8882
./bin/ping-pong 127.0.0.1:8882 127.0.0.1:8880

You can also add additional flags to change algorithm behavior:
