H3C CR19000-20 Router 48Tbps Cluster Performance SDN-Ready & Carrier-Grade Reliability

The H3C CR19000-20 is a next-generation carrier-grade core router designed for high-performance, ultra-scalable networking in operator backbone networks, data center interconnects (DCI), and enterprise core deployments. With 48Tbps cluster performance, SDN-ready architecture, and military-grade reliability, it sets a new benchmark for high-density, low-latency routing.

Key Features & Benefits

Petabit-Level Scalability – Supports 3+12 multi-chassis clustering, scaling up to 72 chassis for future expansion. Delivers 48Tbps full-mesh throughput with 480x100G ports at zero packet loss.
SDN & Cloud-Optimized – Fully SDN-compatible with NETCONF/YANG, BGP-LS, and PCEP for seamless integration with SDN controllers. Features cloud-based cluster control for uninterrupted operations.
Carrier-Grade Reliability – Distributed control/forwarding planes, N+M redundancy, NSR/GR (Non-Stop Routing), and sub-50ms failover ensure 99.999% uptime.
Energy-Efficient Design – Direct-through airflow cooling and liquid cooling support reduce power consumption by 30% vs. traditional routers.
Advanced Routing & Security – Supports MPLS, SRv6, EVPN, VxLAN, and network slicing for multi-service isolation.
