Overload Protection at Endpoint
For endpoints, the SMF offers overload protection at both the endpoint and client levels. The SMF defines the overload threshold limits for the inbound request messages. Based on the threshold range, the SMF can reject the inbound request messages. The SMF sends back an HTTP response with the configured status to the request initiator.
The following are the overload threshold limits defined in the SMF:
Low – When this threshold is met, only the POST method (with generic URI contributing to resource allocation) is rejected.
High – All messages are rejected with the configured (reject) statuses when this threshold is met.
Critical – All messages are rejected with the configured (reject) statuses when this threshold is met.
