### Example flow
|

The simplest configuration deploys a Router on each NameNode machine.
|
||||
The Router monitors the local NameNode and its state and heartbeats to the State Store.

||||
The Router monitors the local NameNode and heartbeats the state to the State Store.
|
||||
When a regular DFS client contacts any of the Routers to access a file in the federated filesystem, the Router checks the Mount Table in the State Store (i.e., the local cache) to find out which subcluster contains the file.
|
||||
Then it checks the Membership table in the State Store (i.e., the local cache) for the NameNode responsible for the subcluster.
|
||||
After it has identified the correct NameNode, the Router proxies the request.
