 * 8.18.  Session-Server-Failover AVP

   The Session-Server-Failover AVP (AVP Code 271) is of type Enumerated
   and MAY be present in application-specific authorization answer
   messages that either do not include the Session-Binding AVP or
   include the Session-Binding AVP with any of the bits set to a zero
   value.  If present, this AVP MAY inform the Diameter client that if a
   re-auth or STR message fails due to a delivery problem, the Diameter
   client SHOULD issue a subsequent message without the Destination-Host
   AVP.  When absent, the default value is REFUSE_SERVICE.

   The following values are supported:

   REFUSE_SERVICE 0

      If either the re-auth or the STR message delivery fails, terminate
      service with the user and do not attempt any subsequent attempts.
      
   TRY_AGAIN 1

      If either the re-auth or the STR message delivery fails, resend
      the failed message without the Destination-Host AVP present.

   ALLOW_SERVICE 2

      If re-auth message delivery fails, assume that re-authorization
      succeeded.  If STR message delivery fails, terminate the session.

   TRY_AGAIN_ALLOW_SERVICE 3

      If either the re-auth or the STR message delivery fails, resend
      the failed message without the Destination-Host AVP present.  If
      the second delivery fails for re-auth, assume re-authorization
      succeeded.  If the second delivery fails for STR, terminate the
      session.
