Apache FreeMarker is a templating language used to create dynamic webpages. It is designed to separate the configuration and data states, allowing the template to have a consistent look and feel across all webpages. FreeMarker allows the template to instantiate the data, allowing the template to be reused in different contexts. It does not allow communication between NSP applications or transport YANG data.

 a Kafka topic is a channel where publishers (producers) publish data and where subscribers (consumers) receive data. A topic represents a stream of messages of a particular category. 

In Kafka, a topic represents a stream of messages of a particular category or type. Producers publish messages to a specific topic, and consumers subscribe to and read messages from topics. Brokers are responsible for managing topics and ensuring that messages are distributed efficiently across the cluster.

Service Fulfilment API does not provide alarm monitoring; rather, it allows customers to quickly and easily order and provision services from a single interface, allowing for increased service agility and reduced human error.

According to the Nokia NSP Service Fulfilment API User Guide, Service Fulfilment API offers the following benefits:

A. Increases service agility by providing a programmable interface for automated service provisioning and management, allowing network operators to quickly respond to customer demands and network changes.

B. Reduces human errors by automating the service provisioning process, which minimizes the risk of manual configuration errors and improves service quality.

C. Allows multi-vendor service provisioning by providing a vendor-agnostic interface that supports different types of network equipment and technologies, reducing vendor lock-in and enabling greater network flexibility.

Terminal emulation configuration is not one of the building blocks of NSP automation. The building blocks of NSP automation are Model-driven mediation, Analytics & telemetry, Multi-vendor support and Automation scripting. Model-driven mediation enables the automation of common tasks across multiple vendors and devices, and analytics & telemetry enables the gathering of critical data to ensure service quality. Multi-vendor support enables the automation of tasks across multiple vendors, and automation scripting enables the development of robust and secure automation scripts.

NSP automation is based on four key building blocks:

• Model-driven mediation: This enables NSP to communicate with various network devices and protocols using a common data model and abstraction layer. It supports YANG models, NETCONF, RESTCONF, SNMP, TL1 and CLI2.
• Analytics & telemetry: This enables NSP to collect and analyze network data using streaming telemetry, SNMP polling, syslog and other methods. It supports various analytics applications such as Network Insight, Service Assurance and Traffic Engineering2.
• Multi-vendor support: This enables NSP to manage and automate networks that consist of devices from different vendors and technologies. It supports Nokia SROS devices as well as third-party routers, switches and optical equipment3.
• Programmable APIs: This enables NSP to expose its functionality and data to external applications or systems using RESTful APIs. It supports various use cases such as network supervision, service fulfillment, fault management and workflow management2.
