Service Models Explained

Abstract

The IETF has produced many modules in the YANG modeling language. The majority of these modules are used to construct data models to model devices or monolithic functions.

Intent-based Network Management and Orchestration for Smart Distribution Grids

“…Intents are integrated into the service design process and augment an automated intent processing mechanism to convert abstracted user requirements into service and resource provisioning configurations for the underlying network orchestrators. The network creates a service model comprising of a customer service model and a service delivery model from the translated user requirements acquired through the customer intents [11]. Network function virtualization (NFV) has enabled the automation in the deployment of required network functions for different service models in a servicecentric network environment.…”

“…Several feasibility checks are performed in order to ensure the required services are made available to the users, including the possible tradeoffs between different services and the dynamic nature of user requirements. A service model can be represented in the YANG modeling language [11], and following service orchestration, it instructs the network orchestrators to provision the required functionality for ensuring the generated service profiles for different user applications. The information exchange in the form of NEST profiles (Fig.…”

Fog computing systems: State of the art, research issues and future trends, with a focus on resilience

“…The requirements of emerging applications can be specified in YANG service modules [165], including a description of how each application is expected to be experienced by the customer. To give an example, a service model can be associated with video traffic.…”
