2083766 - Is the Relay Server application-aware? How behaves the Relay Server? - SMP/SUP

Symptom

  • In what sense is the Relay Server application aware for application servers running MobiLink?
  • Is it possible that connections are dropped because the MobiLink application server is no longer available, or will the Relay Server route this to another application server without package loss?
  • What happens when there was a connection with application server A and the Application Server goes down, can application server B pick up this connection and continue processing (get the remaining packages/chunks assigned)?
  • Can the Relay Server do request throttling, preferably based on the information it gets from the application server?
    It would be preferable to use request throttling (based on the application server and MobiLink instance running on it), to avoid overloading the application servers. This would entail that the requests are queued by the Relay Server when a certain threshold of number of connections has been reached and it takes the number of connections to a specific application server into account when forwarding requests.
