For the purpose of supporting multiple service types (such as high speed Internet (HSI), voice over IP (VoIP), video on demand (VoD) and Broadcast TV) for a single subscriber, the hosts associated with a subscriber can be subdivided into multiple SLA profiles.
The SLA profile contains those QoS and security settings which are applicable to individual hosts. An SLA profile acts like a template and can be used by many subscribers at one time. Settings in the SLA profile include:
Egress and ingress QoS settings
Egress scheduler policy HQoS
Egress and ingress IP filters
Host limit
If the SLA profile does not explicitly define an ingress or egress QoS policy, the default SAP ingress or default SAP egress QoS policy is used.
See Determining the SLA profile for information about how the SLA profile is determined for dynamic hosts.
