The Nokia Network Services Platform (NSP) is architected around modern, model-driven automation principles. Its core building blocks include model-driven mediation (using YANG models and protocols like NETCONF/gNMI), analytics & telemetry for closed-loop operations, and robust multi-vendor support to manage heterogeneous networks. Terminal emulation configuration, which relies on legacy CLI scripting, is a traditional, more brittle approach that model-driven automation is designed to supersede. While NSP can interface with legacy devices via CLI through its mediation layer, this method is not considered a foundational building block of its modern automation architecture.

B. Model-driven mediation: This is a fundamental building block of NSP, using standardized data models (YANG) to abstract network configuration and state, ensuring consistency and reliability.

C. Analytics & telemetry: This is an essential component for NSP's advanced automation, enabling the collection and analysis of network data to drive intelligent, closed-loop actions.

D. Multi-vendor support: This is a key architectural feature of NSP, allowing it to provide a single, unified automation platform for networks composed of equipment from various vendors.

1. Nokia Network Services Platform (NSP) Data Sheet. This document outlines the core capabilities of NSP. On page 2, under "Key capabilities," it explicitly lists "Model-driven multi-vendor mediation for configuration and real-time state" and "Real-time telemetry and analytics for network monitoring and assurance," confirming options B, C, and D as core components. The document's focus on model-driven approaches implicitly positions CLI-based methods as a legacy integration point, not a core building block.

2. Nokia White Paper: "The five-step journey to network and service automation". This paper details the evolution of network management. On page 4, it describes the transition from "Step 1: Manual operations" (characterized by CLI) to "Step 3: Domain automation," which is "based on model-driven principles." This highlights that terminal emulation (CLI) is a method to be automated away from, not a building block of the modern automation platform itself.

3. Nokia Application Note: "Automating network operations with the Nokia Network Services Platform (NSP)". In the section "A model-driven, programmable and extensible platform" (page 5), the document states, "The NSP is a model-driven platform that uses YANG as its core modeling language... This model-driven approach enables NSP to support multi-vendor networks." This reinforces that model-driven mediation and multi-vendor support are foundational pillars.
