Network Operations

Description

The Network Operations software suite enables operators to manage multi-vendor networks using mechanisms such as SNMP or MDM. The feature packages enable configuration, supervision, and assurance functions, and provide telemetry and analytics reporting.

The Network Operations feature packages are:

• Network Infrastructure Management

• Service Assurance

• Service Activation and Configuration

• Network Operations Analytics

• Transport Slice Operations

Network Infrastructure Management

Network Infrastructure Management is a mandatory feature package that provides mediation-agnostic device management. Network Infrastructure Management uses the Platform feature package with either the Base Services or Pluggable Network Adaptation installation option for communication with the network.

The Network Infrastructure Management functions are enabled using the installation options described below.

Basic Management

The Basic Management installation option includes network management capabilities such as network mediation, network infrastructure and service management, and fault management, which are spread among various NSP functions:

Basic Management also includes various KPI dashboards and provides API access to NSP functions.

The Basic Management internal services use the NSP data synchronization framework to ensure that the NSP network infrastructure view is current and consistent with the actual network configuration. The NSP OAM framework manages the execution of various infrastructure tests.

Device Config

The Device Config installation option provides zero-touch provisioning (ZTP) and infrastructure configuration management (ICM) for model-driven device management..

Performance Indicators And Alerts

The Performance Indicators and Alerts installation option enables you to define and monitor network key performance indicators (KPIs), and create threshold-crossing alerts based on the KPIs.

IGP topology

The IGP Topology installation option provides the IGP topology information that is required to populate the IGP topology map in Network Map and Health and the IGP layer in the Object Troubleshooting multi-layer map.

Simplified RAN Transport

The Simplified RAN Transport (SRT) installation option provides SRT dashboard views in the Network Health application. Specifically, the SRT-specific network health summary displays the health of T-BTS nodes and their associated radio plane bindings. See the NSP Simplified RAN Transport Solution for information about the installation options that are required for T-BTS management.

gnmiTelemetry

The gNMI telemetry installation option enables gNMI telemetry collection for classic and model-driven devices.

gNMI onChange

The gNMI onChange installation option enables NE mediation using gNMI.

Service Assurance

The Service Assurance feature package provides mediation-agnostic monitoring and troubleshooting of multi-vendor IP/MPLS and Ethernet services.

The Service Assurance functions use the NSP OAM framework to invoke and manage service-level tests, and the NSP data synchronization framework to ensure that the NSP view of the network infrastructure is consistent with the actual network configuration.

Service Activation and Configuration

The Service Activation and Configuration feature package licenses customers to use any one of the following:

• NSP service management

• NSP classic management component, NFM-P

The mediation-agnostic, multi-vendor service provisioning and activation features within this feature package use operator-defined policies to guide dynamic network resource selection and automated service provisioning, and can execute pre- and post-activation workflows using the NSP Workflows framework. Service Activation and Configuration also includes a service management REST API.

Service management

The NSP service management function adds the programmability of the intent management framework to service provisioning and activation. The programmability supports flexible service constructs and hot-deployable models, and extends to augmentation that supports new NSP service offerings without an NSP upgrade. Nokia provides a set of predefined service models (intent types) for a variety of services. See the NSP Service Management Guide for more information.

Network Operations Analytics

The Network Operations Analytics feature package provides a pre-integrated solution that enables operators to better understand how their network works. The feature package provides full L0-L7 analytics with detailed visualizations and also real-time analysis from hardware inventory to L2 and L3 services by collecting, warehousing and aggregating event, performance and volumetric data.

Analytics

Prepackaged reports and dashboards are integrated with the Nokia SR portfolio regardless of the mediation layer and mode the network elements are running in. Drag-and-drop and web-based tools are provided to create insightful ad-hoc reports and dashboards to enable self-service reporting. Analytics is installed via RPM.

Baseline analytics

The Baseline Analytics installation option is used to enable baselining and anomaly detection that are ideally suited for advanced event-based and closed-loop automation use cases. Baselines automatically learn the normal behavior pattern for selected network and service resources. Anomalies can be triggered when a deviation from the normal historical pattern is observed. This advanced capability can provide an early warning of unforeseen network issues and provide additional time for mitigation and resolution. Baselines are configured and visualized using Data Collection and Analysis.

Transport Slice Operations

Transport Slice Operations is a feature package that enables the 5G Transport Slice Controller dashboard. The dashboard provides a summary of the overall health of all transport slices in the network, as well as allowing drill-down into health views on a per-slice basis. The TSC dashboard displays details about L0/L1/L2/L3 services and tunnels/paths used during the realization of transport slices, and provides pro-active monitoring telemetry data and reports on transport slices.

Note: The Service Activation and Configuration feature package is required with the Transport Slice Operations feature package in all use cases.

Depending on your use case, you may require feature packages in addition to Service Activation and Configuration:

If your deployment uses FlexAlgo - a nodal capability for optimal path selection - then no additional packages are needed.

If your deployment uses the centralized NSP PCE (NRC-P) for manual or automatic [LSP] traffic re-routing, then it requires either:

• Control and Visualization Starter FP + Path Control and Optimization FP, or

• Control and Visualization Starter FP + Path Control and Optimization FP + Enhanced Optimization FP (if your deployment uses the extra precision/options of telemetry-based optimization and/or traffic-engineered ECMP)
