Carrier-Grade Infrastructure Solution Brief: Deploying Bulk Network Routers

CARRIER-GRADE INFRASTRUCTURE SOLUTION BRIEF: DEPLOYING BULK NETWORK ROUTERS

EXECUTIVE SUMMARY

ApexTel™ Bulk Network Router Series (BNR9000) represents a paradigm shift in high-density, carrier-grade edge and core routing. Designed for telecommunications providers, large-scale data center interconnect (DCI), and national research networks, the BNR9000 series decouples control plane intelligence from the forwarding ASIC, delivering deterministic sub-microsecond latency and JEDEC-qualified hardware reliability. This document provides a comprehensive technical overview, performance specifications, and deployment architecture guidance for network architects and procurement specialists.

SYSTEM ARCHITECTURE & CHASSIS DESIGN

The BNR9000 is architected around a fully non-blocking, Clos-based switching fabric deployed across a 5RU or 12RU modular chassis. The system separates the control plane (running on dual, hot-swappable supervisor modules with 2.8 GHz octa-core processors) from the data plane (forwarding engines based on the ApexTel Titan-III programmable ASIC). Key architectural highlights include:
– **Virtual Output Queuing (VOQ):** Eliminates head-of-line blocking, ensuring line-rate performance under 95%+ load.
– **In-band Network Telemetry (INT):** Real-time per-packet latency and queue-depth monitoring without external probes.
– **Synchronous Ethernet & IEEE 1588v2 PTP:** Carrier-grade timing delivery for mobile backhaul and 5G transport.

HARDWARE FEATURE SET

– **Forwarding Capacity:** 12.8 Tbps (BNR9000-5RU) | 25.6 Tbps (BNR9000-12RU) full-duplex.
– **Port Configurations:** Up to 48 x 400GE (QSFP-DD), 96 x 100GE (QSFP28), or 192 x 25GE (SFP28) per chassis.
– **Redundancy:** N+1 fabric modules, 1+1 supervisor, and 3+3 power supply units (AC or DC -48V).
– **Packet Buffer:** 48 GB of shared buffer with intelligent congestion management (WRED, PFC).
– **Security Co-processor:** Line-rate MACsec (IEEE 802.1AE) on all front-panel ports with 256-bit encryption.

COMPLIANCE & INDUSTRY STANDARDS

The BNR9000 series is validated against the following regulatory and interoperability standards:
– NEBS Level 3 (GR-63-CORE, GR-1089-CORE) for central office deployment.
– European Union: CE, RoHS, REACH.
– Global safety: IEC 62368-1, UL 60950-1.
– MEF 3.0 (Carrier Ethernet 2.0) certified.
– OpenConfig & gNMI support for streaming telemetry.
