max-outstanding-requests (Diameter Applications)


Hierarchy Level


Limit the number of outstanding requests that the Diameter-based application (function) can retry to a remote server when the requests are improperly answered. Too many requests risks overloading the server and increases the chance of losing messages.

The gx-plus statement limits retries from the Gx-Plus function to the Gx-Plus server using the Gx and JSRC protocols. The ocs statement limits retries from the OCS function to the OCS server using the Gy protocol. The pcrf statement limits retries from the PCRF function to the PCRF server using the Gx protocol.
