Juniper Networks QFX5700 AI-Optimized Leaf Switch

The Juniper Networks QFX5700 is a high-density, modular leaf switch engineered for modern data center fabrics and AI/ML workload environments. Built on a flexible chassis architecture, the QFX5700 supports a mix of 100GbE, 400GbE, and high-speed interconnect options, enabling data center operators to scale bandwidth and port density in alignment with evolving compute and storage demands. It runs Juniper's Junos OS, delivering consistent network operating system behavior across the entire Juniper data center portfolio and supporting advanced automation through NETCONF, YANG, OpenConfig, and Ansible-based toolchains.

Designed The platform supports RDMA over Converged Ethernet (RoCE) with Priority Flow Control (PFC) and Explicit Congestion Notification (ECN), enabling high-throughput, low-latency communication between compute nodes without packet loss. Its deep buffer architecture accommodates the bursty, all-to-all communication patterns characteristic of large-scale AI training and inference jobs.

For enterprise IT and data center teams, the QFX5700 integrates natively with Juniper's Apstra intent-based networking platform, allowing closed-loop automation, real-time telemetry via gRPC/gNMI streaming, and automated compliance validation across multi-vendor fabrics. The switch is well-suited for deployment as a leaf layer device in spine-and-leaf Clos architectures, supporting EVPN-VXLAN for overlay networking, ECMP for traffic load distribution, and segment routing for traffic engineering — making it a capable foundation for both traditional enterprise data center workloads and next-generation AI infrastructure.

Ideal for

• AI and ML training cluster leaf interconnect, providing lossless RoCE fabric with PFC and ECN for GPU-to-GPU east-west traffic in large-scale distributed training environments
• High-density data center leaf layer deployment within spine-and-leaf Clos fabrics using EVPN-VXLAN overlays for scalable multi-tenant workload segmentation
• Storage networking for NVMe-oF and high-performance storage arrays requiring consistent low latency and high-bandwidth connectivity to compute nodes
• Enterprise cloud on-ramp and colocation interconnect, aggregating server access traffic and extending Layer 2/Layer 3 fabrics to WAN and cloud edge infrastructure
• Network automation and intent-based networking deployments managed through Juniper Apstra, with streaming telemetry enabling real-time visibility and proactive congestion management
• Hyperscale and enterprise DevOps environments requiring rapid, programmable fabric provisioning via OpenConfig, NETCONF/YANG, and infrastructure-as-code workflows
