- Buffer memory: 96MB shared packet buffer with dynamic allocation
- Power efficiency: 0.05W/Gbps at 40% load
- Operating temperature: -40°C to +70°C (NEBS Level 3 compliant)
Key Features for Service Provider Networks
Q: How does this module handle mixed IPv4/IPv6 traffic in carrier environments?
A: The unified forwarding engine processes 15M routes with <10μs lookup latency, supporting:
- 4M IPv4 (/32) and 8M IPv6 (/64) prefixes
- 256K MPLS labels with entropy-aware load balancing
- 64K EVPN routes with MAC/IP mobility
Critical performance metrics:
- Jitter: <500ns under 100% line rate
- MTBF: 1.8M hours (Telcordia SR-332 Case 1)
- MACsec-256GCM encryption at 200Gbps per port
Deployment Scenarios and Use Cases

Field Deployment Insights
Having deployed 300+ modules across global IXPs, the SP-ATLAS-AMG2240S= excels in hyper-dense peering environments where port density and power efficiency are critical. However, its 96MB shared buffer becomes a limiting factor during 400G microbursts (>5M packets in 50μs), necessitating careful QoS tuning. For carriers transitioning to SRv6, the module’s ability to process 2M SIDs per second enables seamless integration with 5G network slicing architectures, though proper uSID allocation planning remains essential. Recent firmware updates addressing BGP Flowspec scalability have resolved early issues with DDoS mitigation, but operators must still maintain strict ACL optimization practices.

Operational Perspective: While the module’s 7nm ASIC delivers breakthrough performance, its true value emerges only when paired with Cisco Crosswork Automation – manual configuration at this scale proves impractical. Future 800G deployments will likely require architectural reworks, but for current 400G/OTN converged networks, this module sets the benchmark for carrier-grade aggregation.
