Pool User

A Pool User (PU) is a client in the Reliable Server Pooling (RSerPool) framework.

In order to use the service provided by a pool, a PU has to proceed the following steps:

• Ask a Pool Registrar for server selection (the Pool Registrar will return a list of servers, called Pool Elements),
• Select one Pool Element, establish a connection and use the actual service,
• Repeat the server selection and connection establishment procedure in case of server failures,
• Perform an application-specific session failover to a new server to resume an interrupted session,
• Report failed servers to the Pool Registrar.
