DetNet Flow Information Model
draft-ietf-detnet-flow-information-model-02
Abstract
This document describes flow and service information model for
Deterministic Networking (DetNet). The DetNet service is provided
either for a Layer 3 or a Layer 2 flow. This document provides
DetNet flow and service information model both for Layer 3 and Layer
2 flows in an integrated fashion.
