1. l The leader starts accepting connections from followers.
2. f Followers connect the the leader and send SERVERINFO(lastZxid, info).
3. l The leader sends SERVERINFO(lastZxid, info) to followers that connect.
4. l Once the leader has quorum, it stops accepting connections, and sends NEWEPOCH(e) to all followers, where e is greater than all f.acceptedEpoch in the quorum.
5. f Followers send ACK(e<<32) When the follower receives NEWEPOCH(e) it will do one of the following:
   • if e > f.acceptedEpoch
   . (If e < f.acceptedEpoch
   • , the
   follower will abandon the leader. If
   • the follower sets f.acceptedEpoch = e and sends ACK(e<<32);
   • if e == f.acceptedEpoch, the follower
   will
   • does not send ACK(e<<32), but
   will still maintain
   • continues to next step;
   • if e < f.acceptedEpoch, the follower closes the connection to the leader
   .)
   • and goes back to leader election;
6. l The leader waits for all followers to ack NEWEPOCH(e)
7. l If the following conditions are not met for all connected followers, the leader disconnects followers and goes back to leader election:
   • f.currentEpoch <= l.currentEpoch
   • if f.currentEpoch == l.currentEpoch, then f.lastZxid <= l.lastZxid
