Description
Specify the destination and transmission parameters for the Diameter Network Access Server Requirements (NASREQ) protocol.
NASREQ is a Diameter-based authentication and authorization protocol. The NASREQ client has two queues, the transmit queue and response queue. The transmit queue stores outbound packets until sent to Diameter, and includes requests and responses. The response queue stores request packets until Diameter responds to the request, and includes only requests waiting for a response.
The following configuration options control transmission flow and use of the queues:
max-outstanding-requestsoption specifies the maximum number of requests (includes AAR and STR) that the NASREQ client sends to Diameter for wireline transmissions. Effectively, this is the maximum count of requests on the response-queue (the maximum number of in-flight requests for which there has not been a response or timeout); it does not include sent responses.The
request-retryoption specifies how many times the NASREQ client retries transmitting a packet to the Diameter server when a timeout is received from the Diameter server for the request.The
timeoutoption specifies the number of seconds that an outbound packet remains in the transmit queue before it is declared to have timed out. The NASREQ client does not transmit packets that have timed out. The timeout value applies to all packets in the transmit queue, including both requests and responses to be sent. Diameter manages packets that time out after transmission.
Options
| number | Maximum number of requests that the NASREQ client sends to Diameter.
|
| retries | Number of times to re-send a timeout request to Diameter after the initial request. This value applies only to requests in the response queue. A value of 0 indicates to try transmission once and then do not retry.
|
| seconds | Number of seconds that an outbound packet remains in the transmit queue before it is declared to have timed out.
