Description
Server failover is transparent to the Client: the Client does not care or even know that failover has occurred.

Usage Considerations

  • No Client code required to keep connection operational.
  • Clients able to determine
    • which Servers are in the redundant set
    • the service level of each server
    • which Server is currently responsible for the client session
    • Client-Server connection information is synchronized across servers

Conformance Testing

Client Server

Nothing needed in the CLient.
