Table 1: Supported Platforms and Positioning
Platform Device Positioning
Device Under Testing (DUT) Platforms ACX710 and ACX5448 ACX710 is selected as the primary DUT for access role as 5G and/or 4G CSR
Helper Platforms ACX710 and ACX5448 Access Nodes (AN1, AN2, AN3) cell site routers
ACX5448

AG1 Pre-Aggregation hub site routers (HSR)

AG1.1 and AG1.2 are deployed as redundant route reflectors with access client peers.

MX204 Aggregation routers AG2.1/AG2.2
MX10003/MX480 Aggregation routers AG3.1/AG3.2
MX10003 Core routers CR1/CR2. PTX1000 Router is used for core role (CR1). CR1 and CR2 act as redundant route reflectors with client peers of AG1.1 and AG1.2.
MX10003 Service router SAG (SAG)

Scale and Performance

This section contains key performance indexes (KPIs) used in solution validation targets. Validated KPIs are multi-dimensional and reflect our observations in customer networks or reasonably represent solution capabilities. These numbers do not indicate the maximum scale and performance of individual tested devices. For uni-dimensional data on individual SKUs, kindly contact your Juniper Networks representatives.

The Juniper Networks JVD team continuously strives to enhance solution capabilities. Consequently, solution KPIs may change without prior notice. Always refer to the latest JVD test report for up-to-date solution KPIs. For the latest comprehensive test report, please reach out to your Juniper Networks representative.

Solution Validation Goals

Here are the major test goals:

  • Validation of network stability and pre-slicing functionalities for Seamless SR 5G xHaul design architecture:
    • End-to-End Seamless SR across ISIS L1 and L2 domains and Inter-AS BGP-LU stitching.
    • Flex-Algo with red (128) and blue (129) FADs IGP & TE metrics.
    • BGP-CT creation of transport RIBs for underlay and service mapping functions using bronze and gold extended color communities.
    • Color-mapping results in deterministic path selection and traffic steering.
  • Validation of overlay service mapping (service slicing):
    • BGP-CT service/prefix mapping per supported VPN type (L3VPN, L2VPN, and Layer 2 circuit (L2CKT))
    • Validate BGP-CT Resolution Scheme fallback operations.
    • BGP-VPLS performs color agnostic path selection.
  • Validation of network stability for major 4G/5G traffic flows at scale with each VPN service type over Seamless SR during normal and stress conditions.
  • Validation of network resiliency, the ability for seamless traffic restoration, and measured convergence time for ACX710 AN and ACX5448 AN/AG, along with adjacent links and node failures for all services/traffic flows.
    • Solution resilience of layer 2/3 flows from AN to AG1, AG1 to SAG and AN to SAG (EPC).
  • Validation of consistency and resiliency of the ACX710/ACX5448 systems against negative stress conditions (enable or disable control and data plane daemons, add or delete configurations, and so on).
  • Identify product limitations and anomalies exposed during validation stages.
