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.

Solution Validation Non-Goals

Non-goals represent protocols and technologies outside the scope of this JVD:

  • Class of Service (CoS).
  • Underlay MPLS/SR transport other than specified in the Solution Goals section.
  • Multi-Instance ISIS.
  • OSPF as L3VPN routes only.
  • EVPN over colored transport BGP-CT.
  • Management and Automation.
  • BGP PIC-Edge at border routers.
  • End-to-End Timing and Synchronization Distribution:
    • Synchronous Ethernet
    • IEEE1588v2
  • SLA Monitoring: RFC 2544, Y.1564, TWAMP, Active Assurance
  • Telemetry
  • Loopback filters on DUT

The regulatory trends are as follows:

  • 3GPP Forum
  • O-RAN Alliance
