Core Technical Architecture The Cisco...
Hardware Architecture & Functional Overview
The NC55P-BDL-36HT is a specialized interface bundle for Cisco’s NCS 5500 series routers, designed to address three critical service provider challenges:
- High-Density 100G/400G Aggregation – 36x QSFP-DD ports with 14.4 Tbps bidirectional throughput
- Modular Service Flexibility – Mix of 4x100G, 8x25G, and 2x400G breakout configurations per port
- Energy-Efficient Design – 0.38W per Gbps at full load, 40% improvement over previous generations

Operational Reliability Insights
Field Performance Data
- MTBF: 147,000 hours (16.8 years) in 24/7 operation
- Common Configuration Errors:
- Mismatched FIB/RIB scaling limits causing BGP session flaps
- Oversubscribed QoS policies triggering buffer starvation
Final Operational Assessment
The NC55P-BDL-36HT redefines core routing economics – its hardware-assisted telemetry pipeline enables real-time jitter measurement at nanosecond granularity, critical for 5G timing-sensitive applications.
