Core Specifications and Design Philosophy
The Cisco ASR-9006-AC-V2 is a 6-slot aggregation router optimized for high-density traffic handling and AC power redundancy. Designed for service providers and enterprises, it delivers 3.6 Tbps per slot using Cisco’s Quantum Flow Processor and supports mixed-speed interfaces (1G/10G/100G) for seamless integration with legacy and next-gen infrastructure. Key technical parameters include:
- Power Supply: Dual 100–240V AC inputs with 99.999% uptime, reducing energy costs by 18% compared to DC variants.
- Environmental Resilience: Operates at -10°C to 55°C with IP54-rated chassis for industrial deployments.
- Security Compliance: Meets FIPS 140-2 Level 2 and China’s GB40050-2021 standards.
Technical Innovations and Deployment Scenarios
AC Power Efficiency Over Legacy DC Models
The ASR-9006-AC-V2 eliminates DC grid dependency and AC/DC conversion losses, achieving 15–20% lower total cost of ownership (TCO) over 5 years. Adaptive power scaling dynamically adjusts to traffic loads, critical for energy-sensitive sectors like data centers.
VoQ Architecture for Congestion-Free Traffic
Leveraging Virtual Output Queuing (VoQ), this router prevents head-of-line blocking through Fabric Interface Adapter (FIA)-managed credit scheduling. This ensures low latency for applications like 5G backhaul and IoT edge networks.
SDN and Multi-Vendor Interoperability
The router supports EVPN/VXLAN for hybrid cloud deployments. Validated with Juniper MX240 and Huawei NE40E-X2-M8A routers, it integrates seamlessly into multi-vendor SDN ecosystems.
ASR-9006-AC-V2 vs. ASR-9006-DC: Critical Comparison
| Feature | ASR-9006-AC-V2 | ASR-9006-DC (Legacy) |
|---|---|---|
| Power Efficiency | 1800W adaptive scaling | 2100W fixed draw |
| Cooling System | 40% improved airflow | Standard thermal design |
| Deployment Cost | Lower TCO over 5 years | Higher maintenance |
| SDN Compatibility | EVPN/VXLAN-ready | Limited programmability |
Addressing Key Deployment Questions
Q: Why prioritize AC power in modern network upgrades?
A: AC infrastructure is globally standardized, simplifying deployment in regions without DC grids. The dual redundant modules ensure zero downtime during power fluctuations, aligning with SLAs for sectors like healthcare and utilities.
Q: How does it handle 100G traffic congestion in high-density environments?
A: The Tomahawk line cards integrate 32x100G ports with 12 MB deep buffers per port. Combined with VoQ scheduling, this prevents packet loss in scenarios like video streaming or autonomous vehicle V2X communication.
Q: Is it backward-compatible with older ASR 9000 Series modules?
A: Yes. The AC-V2 supports legacy cards like the A900-IMA1C (100GE CPAK), enabling cost-effective upgrades from ASR-9006-DC deployments without chassis replacement.
For organizations prioritizing energy efficiency, terabit scalability, and regulatory compliance, the ASR-9006-AC-V2 remains a cornerstone of Cisco’s edge routing portfolio. Its modular design and SDN readiness future-proof investments in smart city infrastructures and hyperscale cloud connectivity.
