Orchestration is the function defined via a process specification that is executed by an orchestrator component which automates sequences automates the sequencing of activities, tasks, rules and policies needed for on-demand creation, modification or removal of network, application or infrastructure services and resources. The Master Service Orchestrator (MSO) provides orchestration at a very high level, with an end-to-end view of the infrastructure, network, and application scopes.
The Master Service Orchestrator’s (MSO’s) primary function is the automation of end-to-end service instance provisioning activities. MSO provides the BSS systems an interface to orchestrate delivery of D2 cloud services.
BSS End to End Orchestration will decompose the customer request in to D2 into cloud and non-D2 cloud services based on rules from the product catalog. The BSS End to End Orchestration triggers the MSO to initiate ECOMP activity, and the MSO manages the provisioning/network activity by interacting with Controllers as required. The MSO sends the business level status back to the BSS Orchestration. The BSS Orchestration does not maintain provisioning logic nor manage provisioning processes.
