A coordinator is used to sychronise the usage of resources in a distributed system.

The Bully Algorithm is a method to elect a new coordinator in a distributed system when the current coordinator disappears for some reason.

I am just wondering what happens when two processes realise the demise of the coordinator simultaneously and both decide to hold an election using the Bully Algorithm?

Both processes will anounce themselves. However, the one with the highest indentifier will become the leader. For example, 3 and 4 announce themselves. 3 asks who has an id greater than me, and 4 responds. Then 3 knows 4 is the new leader. 4 does the same. No process replies. 4 tells everyone that he's the new leader.
