About This Document

This document explains a Juniper Validated Design (JVD) for building and deploying a 5G xHaul solution architecture using the Juniper ACX7000 series, MX series, and PTX series platforms. This JVD extends solutions that are provided previously with 5G CSR Seamless Segment Routing and 5G Fronthaul Class of Service for the focused delivery of differentiated services supporting ultra-low latency workloads. Comprehensive Quality of Service (QoS) in the 5G network architecture is mandatory to ensure reliable and efficient performance across diverse applications and services. QoS mechanisms prioritize traffic, manage bandwidth, and preserve latency budgets, ensuring critical applications receive the necessary resources and maintain overall network performance and user experience. The capabilities and performance of the 5G network become paramount as technological advancements are considered to support autonomous driving, remote surgery, industrial automation, and other mission-critical services.

The functional and performance aspects of Fronthaul services and Class of Service (CoS) operations are thoroughly analyzed to support multi-level traffic priorities with low latency queuing. After conducting rigorous testing, Juniper ACX7024, ACX7100, and ACX7509 provide scalable and flexible platforms for implementing CoS in 5G Fronthaul networks. These routers offer robust performance, high port density, and advanced traffic management capabilities, allowing seamless expansion and adaptation to evolving network requirements.

This JVD is based on 5G reference architectures. However, you can apply the CoS modeling, best practices, and performance results to many implementations.
