PRODUCT OVERVIEW AND EXECUTIVE SUMMARY
The NexaCentric 8000 Series represents a paradigm shift in Wide Area Networking, engineered explicitly as a hardware-forwarding plane for Software-Defined Networking (SDN) architectures. These routers decouple the proprietary control plane from high-performance data forwarding, enabling full compatibility with open-standard SDN Controllers (OpenFlow 1.3+, NETCONF/YANG, and gRPC). Designed for the AI-driven transport era, the 8000 Series provides line-rate throughput, deep buffer telemetry, and real-time programmability.
ARCHITECTURE & CHASSIS DESIGN
The system is built upon a distributed, non-blocking CLOS fabric architecture. The central chassis supports a 2+1 redundant Fabric Card set and utilizes a 500 Gbps per-slot backplane. The hardware pipeline integrates a programmable P4-capable ASIC (NexaFlow-3), allowing operators to push forwarding behaviors directly from the controller without firmware upgrades. Key architectural tenets include: Flow-based load balancing, In-band Network Telemetry (INT) insertion, and hardware-native Segment Routing MPLS/SRv6.
HARDWARE FEATURES & PERFORMANCE ENVELOPE
– Centralized SDN Agent: Dual-core ARM Cortex-A72 control complex running a lightweight, controller-dominant OS.
– Interface Density: Up to 36 x 100G QSFP28 ports or 4 x 400G OSFP ports per 2RU slot.
– Forwarding Capacity: 3.2 Tbps per line card; 12.8 Tbps per chassis.
– Telemetry: Hardware timestamping at 1 nanosecond resolution for gNMI streaming.
– Security: MACsec 256 (802.1AE) on all front-panel ports.
COMPLIANCE & STANDARDS
