Overview #

The RG-N18000-XH series from Ruijie Networks is a next-generation, high-performance core switch designed for data center environments and DCI (Data Center Interconnect) scenarios. The series leverages cutting-edge CLOS cell-based architecture with a zero-backplane design, offering industry-leading performance, scalability, and energy efficiency. It is a future-proof solution supporting 400G and 100G interfaces, with a long-term evolution path toward 800G.

The RG-N18000-XH series includes two main models:

• RG-N18018-XH: Supports up to 576x400GE ports.
• RG-N18010-XH: Supports up to 288x400GE ports.

This product line is ideal for ultra-large-scale data centers, enabling maximum flexibility, scalability, and reliability.

Key Features #

1. Zero-Backplane Design for Maximum Efficiency #

The zero-backplane design of the RG-N18000-XH series allows direct connection between business line cards and the switching network boards, without requiring an intermediary backplane. This architecture minimizes transmission losses, significantly boosting traffic handling efficiency within the switch and enhancing its overall performance and capacity.

Key benefits include:

• No backplane bottleneck: The direct line card-to-switching board interface ensures maximum internal transmission efficiency.
• Future-proof architecture: Designed with future upgrades in mind, it supports a long-term evolution path to 800G bandwidth without needing to replace the chassis.

2. CLOS Multi-Plane Non-Blocking Switching Architecture #

The switch employs a CLOS cell-based multi-plane architecture that provides fully non-blocking switching. By separating the forwarding and control planes, the system offers higher operational efficiency, scalability, and enhanced fault tolerance, ensuring seamless operation in even the most demanding environments.

• Independent Switching and Control Boards: The architecture allows for non-blocking, full line-rate switching across all ports.
• High Scalability: Supports up to 576x400GE line-rate ports, with future support for 800G ports.

3. Front-to-Back Airflow Design #

The front-to-back airflow design ensures optimized cooling for data centers, improving the device’s overall energy efficiency while minimizing fan noise and power consumption.

• High-Density Panel Design: The front panel has a 60% perforation rate, increasing airflow for better cooling.
• Energy-Efficient Cooling: Intelligent fan speed control based on temperature zones improves reliability by 30%.

4. Extensive VXLAN and Overlay Networking Capabilities #

• VXLAN Support: The switch can support up to 16M VXLAN segments, facilitating the creation of large-scale overlay networks within data centers. This addresses the limitation of VLAN scalability in traditional data center networks.
• EVPN Protocol Support: The system enables VTEP (VXLAN Tunnel Endpoints) auto-discovery and authentication, simplifying VXLAN deployment and reducing reliance on multicast for VXLAN operation.

5. Segment Routing Support (SR-MPLS and SRv6) #

The series is designed to support Segment Routing (SR) technology, both for SR-MPLS and SRv6, allowing for more flexible and intelligent traffic engineering.

• SR-MPLS: Provides more flexible traffic path planning at the ingress node, offering better control over business traffic.
• SRv6: This IPv6-based segment routing technology supports the next generation of networking with seamless IPv6 integration, addressing large-scale tenant access requirements.

6. Data Center-Class High Reliability #

The RG-N18000-XH series is built with redundancy at its core, ensuring high availability and business continuity:

• N+M redundancy for switching boards.
• 1+1 management engine redundancy.
• N+M power supply redundancy and 2+1 fan redundancy.
• Hot-swappable modules: All power and fan modules can be replaced without affecting device operation.

Additionally, the switch supports BFD (Bidirectional Forwarding Detection) for rapid failure detection across protocols like VRRP, BGP, IS-IS, OSPF, and RIP, ensuring fast protocol failover and recovery.

7. Hardware-Based Data Encryption #

The switch supports MACSec (Media Access Control Security) for hardware-level data encryption. This provides robust security with data integrity verification and source authenticity checks, ensuring secure communication even in large, complex networks.

8. Long-Distance 400G ZR Optical Module Support #

The series supports 400G ZR optical modules that provide up to 80KM transmission distance, simplifying long-distance DCI interconnections and reducing overall network deployment costs.

Energy-Efficient Innovations #

• Platinum-grade power supplies: Power conversion efficiency up to 94%.
• Low Impedance Copper Busbar Design: Reduces power distribution losses to below 0.3%.
• Phase Change Material (PCM) Cooling: Utilizes advanced cooling technologies such as PCM to improve thermal efficiency by 15°C compared to traditional heat pipes, boosting board reliability by 20%.
