S 3 P Updates Optimization Service Design Framework (OSDF) Performance Stability Homing and Allocation Service (HAS) Level 1, develop plans for performance improvement Level 1 Resiliency Level 2; OSDF is stateless; clients retry requests if OSDF container crashes or times-out. Clients manage timeouts. Security CII Passing Badging – No critical security and licensing issues Increase Code coverage from >50% to >60% AAF based authentication; encrypted communication between components Scalability Level 1 Level 3; HAS provides Active/Active resiliency across multiple sites Level 2 Manageability Level 1; with progress on adherence to Logging v 1. 2 spec Usability Level 1 6

Optimization Framework – R 3 (1/4) • • Service Orchestrator (SO) Change Management Portal SDNC PCI Handler MS Optimization Framework (OOF) • • • Policy Interface Inventory Service Interface Service/Policy Models Interface Infrastructure Metrics Interface MUSIC REST API interface Config data interface, SDNC(R) Definition: - ONAP Optimization Framework (OOF) enables easy creation of optimization applications by leveraging a policy-driven, declarative approach, that supports different specializations (applications) with specific domain and optimization needs. - Current scopes include (but are not limited to) VNF placement support via Homing and Allocation Service (HAS) with different use cases, change management scheduling service, Route Optimization, and PCI Optimization. Provided Interfaces: - Placement Optimization Interface - Provides functionality for the Service Orchestrator to enable optimized homing/placement of Services - PCI Optimization Interface - Provides functionality for PCI Allocation to minimize conflicts and confusion - Route Optimization Interface - Provides functionality for path/route optimization given a topology - Change Management Portal Interface - Provides functionality for calculating schedules that satisfy time constraints and conflicts [CM scheduling use case] Consumed Interfaces: - Policy Interface, from: Policy - Inventory Service Interface, from: Available and Active Inventory - Service/Policy Models Interface, from: SDC - Infrastructure Metrics Interface, from: Multi.
