The Sh Cache Microservice (ShCM) provides a caching layer in front of a Home Subscriber Server (HSS) for certain queries over Diameter Sh.
For a high level architecture overview see: Sh Cache Service Overview
ShCM is realised as two Services running in a Rhino TAS.
The Cache Service processes Diameter Sh/HTTP triggers received by clients.
The Notification Service processes Diameter Sh triggers received from the HSS.
Each software component in the ShCM collects statistics. Components related to the interfaces between the ShCM and external entities may generate alarms.
The following diagram shows the software components used in the Cache Service.
The following diagram shows the software components used in the Notification Service.
