A9K-40GE-L Use Case
Hyperscale Data-Center Spine with A9K-40GE-L-40PORT for Unmatched Throughput
Scenario: A global cloud provider deploys the A9K-40GE-L-40PORT GE Low-Queue line card with SFPs in ASR 9000 series routers as the spine layer in a leaf-spine fabric. Outcome: Consistent sub-millisecond latency under full 1.6 Tbps load, predictable buffer management and zero-packet loss during traffic bursts. Benefit: Scales to thousands of virtual machines, accelerates East-West traffic and maintains SLAs for IaaS and PaaS workloads.
Service-Provider Metro Edge for Ultra-Low-Latency 5G Backhaul
Scenario: A Tier 1 carrier integrates A9K-40GE-L-40PORT line cards at metro POPs to aggregate 5G cell-site backhaul over 40 GE SFP interfaces. Outcome: Deterministic queuing and hardware-based QoS deliver sub-10 µs jitter and end-to-end SLA compliance for voice, video and IoT slices. Benefit: Maximizes port density, simplifies fiber management and future-proofs the edge for 5G/FTTx services.
Enterprise Hybrid-Cloud WAN with High-Density 40 GE Connectivity
Scenario: A multinational corporation leverages the A9K-40GE-L-40PORT in its ASR 9000 backbone to interconnect branch offices and public-cloud gateways via 40 GE SFP links. Outcome: Seamless dynamic bandwidth scaling, sub-1 ms inter-site latency and deterministic buffer allocation for real-time collaboration and data replication. Benefit: Reduces MPLS costs, enhances disaster recovery and accelerates cloud-native application performance.
