Test Objectives

Juniper Validated Designs (JVD) are a cross-functional collaboration between Juniper solution architects and test teams to develop coherent multidimensional solutions for domain-specific use cases. The JVD team comprises technical leaders in the industry with a wealth of experience supporting complex customer use cases. The scenarios selected for validation are based on industry standards to solve critical business needs with practical network and solution designs.

The key goals of the JVD initiative include:

  • Test iterative multidimensional use cases.
  • Optimize best practices and address solution gaps.
  • Validate overall solution integrity and resilience.
  • Support configuration and design guidance.
  • Deliver practical, validated, and deployable solutions.

A reference architecture is selected after consultation with Juniper Networks global theaters and a deep analysis of customer use cases. The design concepts that are deployed use best practices and leverage relevant technologies to deliver the solution scope. Key performance indicators (KPIs) are identified as part of an extensive test plan that focuses on functionality, performance integrity, and service delivery.

Once the physical infrastructure required to support the validation is built, the design is sanity-checked and optimized. Our test teams conduct a series of rigorous validations to prove solution viability, capturing, and recording results. Throughout the validation process, our engineers engage with software developers to quickly address any issues found.

The goal of this JVD is to validate that the MX304, MX10004, ACX7100-48L and ACX7509 devices can meet the requirements of enterprise WAN edge deployments and that the PTX10003 and PTX10001-36MR devices can meet the network requirements of the enterprise core. PTX-systems perform an additional function of a x`. These devices under test are validated with the scale mentioned in the scaling section of this document.

The focus of the validation efforts:

  • Using MPLS LDP with OSPF and TI-LFA.
  • Using segment routing (SR) with OSPF and TI-LFA.
  • Assessing VPN services, including EVPN-VPWS, EVPN-FXC, and EVPN-ELAN for consistency and resiliency over SR-MPLS transport architecture.
  • Evaluating TI-LFA redundancy mechanisms over SR.
  • Testing HQOS with different traffic profiles.
  • Using BGP flowspec and unicast RPF as DDoS protection mechanisms.
  • Validating network resiliency, traffic restoration, and measured convergence time for MX304 (WAN Edge 1), ACX7100-48L (WAN EDGE 4), and ACX7509 (WAN EDGE 3) against adjacent link/node failure across all traffic types.
  • Assessing network stability for major traffic flows at scale with each VPN service type during normal and stress conditions.
  • Evaluating the consistency and resiliency of the device under test (DUT) against negative stress conditions (enable/disable control and data plane daemons, add/delete configurations, and so on.).
  • Identifying any product limitations, anomalies, and open PRs exposed during validation stages.

The testing process focuses on these areas to ensure security, stability and efficiency of the network solutions being developed. The validation stages are designed to identify and resolve any potential issues and to improve the overall performance of the network system.
