[1] Implementation of the Coordinator (Worker type: Loop)
|
|
|
|
The Coordinator coordinates all handlers. He has to accept new handlers,
|
|
give them an task and save information about them to optimize (and recover)
|
|
the network.
|
|
|
|
He also receives all queries, saves them and assignes them to workers.
