MD-IWF Administrative State and Operational Status

The MD-IWF application has an Administrative State and an Operational Status. The Administrative State (or Admin State - enabled or disabled) indicates the state that the operator desires the MD-IWF application to be in. The Admin State can be manually modified by the operator. The Operational Status indicates the actual status of the MD-IWF application.

Table 7-1 lists the MD-IWF Admin State and Operational Status related to the MD-IWF Routed Service State, MD-IWF Routed Service Congestion Level and MD-IWF (internal) congestion levels. It specifies the actions that MD-IWF will take in various situations.

ComAgent DM-IWF Routed Service presents an aggregated view of the all DM-IWF instances (one instance per DA-MP) that have registered as service providers for the DM-IWF Routed Service. ComAgent reports the DM-IWF Routed Service State and the DM-IWF Routed Service Congestion Level to each MD-IWF instance.

In the Diameter to MAP direction, the MD-IWF Operational Status and the DM-IWF Routed Service congestion level determine whether a given Request from DRL can be forwarded to an MD-IWF. The MD-IWF Operational Status is determined by multiple attributes including MD-IWF Admin State, MD-IWF (internal) congestion level, MD-IWF Routed Service State and MD-IWF Service Congestion Level. In Table 7-1, MD-IWF Congestion Level is the maximum of the MD-IWF (internal) Congestion Level and MD-IWF Routed Service Congestion Level.

In Table 7-1, the MD-IWF Admin State, DM-IWF ComAgent Provider Status, MD-IWF Congestion State, and SS7-MP isolated from SS7 network? are the inputs for calculating the MD-IWF Operational Status, MD-IWF Operational Reason, and MD-IWF Operational Color.
