The HSS may report its current load by including a Load AVP of type HOST in answer commands as described in IETF RFC 8583 [43].
The HSS calculates its current load by implementation specific means. For example, the HSS may take into account the traffic over the Sh interface or other interfaces, the level of usage of internal resources (e.g. CPU, memory), the access to external resources, etc.
The HSS determines when to send Load AVPs of type HOST by implementation specific means.
