A9K-2T20GE-L Use Case
Hyperscale Cloud Data Center Spine Aggregation with A9K-2T20GE-L Low-Queue Line Card
In a hyperscale cloud environment, service providers deploy the A9K-2T20GE-L-2PORT 10GbE 20-port GBE low-queue line card (requiring XFP & SFP) as the spine aggregation layer. Its non-blocking 2.4 Tbps throughput and sub-100 µs latency absorb east-west VM migrations and container microbursts, driving SLA compliance. Outcome: 25% reduction in rack-to-rack congestion, consistent low-latency performance, and simplified optics management with mixed 1GbE/10GbE ports.
5G Mobile Backhaul Aggregation & Microburst Mitigation
Telecom operators integrate the A9K-2T20GE-L-2PORT 10GbE 20-port GBE low-queue LC into ASR 9000 for 5G mobile backhaul aggregation. Using XFPs for 10GbE and SFPs for 1GbE, it consolidates multiple cell-site links while the low-queue architecture mitigates microburst-induced jitter. Outcome: 40% lower packet loss during traffic spikes, under-1 ms jitter for fronthaul, and streamlined optics inventory for scalable, SLA-driven 5G services.
Enterprise Campus Core for HD Video Conferencing & IoT
Global enterprises upgrade campus cores with the A9K-2T20GE-L-2PORT 10GbE 20-port GBE low-queue line card, leveraging mixed SFP/SFP+ and XFP optics. It delivers sub-millisecond latency for HD video conferencing and real-time IoT telemetry across thousands of edge devices. Outcome: 30% improvement in video-call MOS scores, seamless high-density IoT data aggregation, and future-proof scalability to 5GbE/10GbE with unified optics management.
