Usage and event management BSSs can be created as applications on top of the DCAE environment as well as applications outside DCAE. These applications can collect customer events and perform mediation of the usage and events to downstream BSSs or OSSs (Operational Support Systems). BSSs can also collect network events such as bill-impacting configuration changes, consumption or any new bill-impacting network product or service . This data which can in turn be used for various purposes such as rating, balance management, charge calculations, and so on.ECOMP Data sources will provide data to BSS for Customer SLA credit processing. SLA Data Sources will collect information needed to perform Customer SLA Management. The ECOMP Data Sources are as follows: DCAE – network measurement, ECOMP Orchestration – service orchestration (activation), Policy – rules/violations, ASDC – SLA Definition, data templates for products. Note that both ECOMP Data sources and BSS will need to be informed about the fields to be gathered for those SLAs by the product definition in ASDC. The actual determination if an SLA has been violated, calculation of credits, and applying those credits to the customer bill will be done by BSS, not ECOMP Data sources. However, if there is an elastic response required based on a SLA violation being approached, the service may require an action by ECOMP to monitor and respond to a defined policyand charge calculations.
