Juniper Networks Turns Transformative Network Architectures into Proven Design with the Lab in the Sky Testing Application
Juniper Networks harnesses the Lab in the Sky Testing Application—purpose-built for production-grade, at-scale network validation—to turn its forward-looking, cutting-edge Juniper Validated Designs (JVD) into proven, production-ready solutions—fast-tracking rollout and giving service providers a head start on next-generation capabilities.
Testing Application Validates Complex End-to-End Service Profiles in Juniper Validated Design ‘Metro as a Service (MaaS)’
Juniper Networks recently developed a new metro network blueprint—Metro as a Service (MaaS)—as part of its Juniper Validated Design (JVD) portfolio. Given the architectural scope and complexity of MaaS, validation under realistic, production-like conditions was essential. To meet this requirement, Juniper leveraged the Lab in the Sky Testing Application to conduct an extensive, end-to-end validation.
The objectives were to confirm service behavior across the full metro domain; verify support for a wide range of Carrier Ethernet service types—including E-Line, E-LAN, E-Tree, EVPN, BGP-VPLS, and L2Circuit; assess scalability, service assurance, and fault resilience; and streamline deployment readiness through pre-validated configurations and automation-aligned testing.
Lab in the Sky played a central role by generating and executing over 12,000 test cases. Its cloud-native, compute-intensive automation environment significantly reduced test time, increased repeatability, and delivered a depth and breadth of test data far beyond what is achievable with conventional frame-level testing methods.
