Product Overview

Product Definition

The Ruijie RG-N18000-XH series represents a new epoch in high-performance core switching, meticulously engineered for the demanding environments of modern data centers and large-scale Data Center Interconnect (DCI) scenarios. These switches leverage a state-of-the-art CLOS (originally from Charles Clos, referring to a multistage circuit switching network topology) direct orthogonal switching architecture, designed to deliver line-rate forwarding across an impressive density of high-speed ports, including 400G, 100G, and 10G Ethernet. A hallmark of the series is its forward-thinking design, which anticipates future bandwidth requirements with a clear roadmap for 800G port evolution. This future-proofing ensures that investments made today will continue to deliver value as network demands escalate. Beyond raw performance, the RG-N18000-XH series incorporates a direct front-to-back airflow design, crucial for optimal thermal management in data center racks, and integrates numerous green energy-saving technologies to significantly reduce power consumption without compromising operational capabilities. The design philosophy emphasizes not just capacity, but also efficiency, reliability, and adaptability to evolving network paradigms like Software-Defined Networking (SDN) and advanced overlay technologies.

Product Models and Family Comparison

The RG-N18000-XH series currently includes two primary chassis models, the RG-N18018-XH and the RG-N18010-XH. These models cater to different scale and density requirements, allowing network architects to choose the optimal platform for their specific needs. Both models share the same advanced architectural principles but differ in physical size, slot capacity, and maximum port density.

This modularity is central to the RG-N18000-XH series’ value proposition, offering granular scalability and flexible deployment options. Organizations can scale their networks incrementally, adding capacity as needed. The foundational architecture, common across the series, features independent switch fabric cards and control engines. This deliberate separation of the data plane (forwarding) from the control plane (management and routing protocols) is fundamental for achieving both high, predictable performance and robust system reliability, preventing control plane issues from impacting data forwarding operations.

Revolutionizing Network Core with Advanced Architecture

The performance and efficiency of a core switch are fundamentally tied to its underlying architecture. The RG-N18000-XH series introduces groundbreaking architectural innovations, specifically its leading-edge zero-backplane design and a sophisticated CELL-based CLOS fabric. These elements work in concert to overcome traditional limitations and deliver a truly next-generation switching platform.

The zero-backplane design is a paradigm shift from conventional chassis-based switches. As stated in the product documentation:

“The RG-N18000-XH series switches adopt a leading-edge zero-backplane design, where service line cards and switch fabric cards directly interface. This eliminates the need for a traditional backplane connection. Cross-card traffic is transmitted directly to the switch fabric for switching, minimizing transmission loss and exponentially increasing the efficiency of business traffic flow within the switch.”

This direct interconnection philosophy has profound implications. Traditional backplanes, while enabling modularity, can become a bottleneck. They introduce signal integrity challenges, contribute to latency, and can limit the overall bandwidth potential of the system, especially as port speeds increase. By removing the backplane, the RG-N18000-XH series achieves shorter, more direct signal paths between line cards and the switching fabric. This not only reduces signal degradation and power consumption associated with driving signals across a large PCB but also significantly enhances internal data transfer speeds. The benefits are manifold: higher effective throughput for applications, lower end-to-end latency, and a more robust physical layer. Crucially, this design “infinitely expands the switch’s performance and switching capacity” and “greatly enhances the device’s upgradeability, ensuring that even future upgrades to 800G bandwidth can be achieved without replacing the chassis.” This provides significant investment protection and a clear path for future growth.

Complementing the zero-backplane design is the adoption of a CELL-based CLOS architecture. The documentation highlights:

“The RG-N18000-XH series switches employ a brand-new CLOS multi-stage, multi-plane switching architecture, achieving complete separation of the forwarding and control planes. It enables the configuration of independent switch fabric cards and independent main control boards. The CELL-based switching architecture ensures full line-rate non-blocking performance between ports, providing continuous bandwidth upgrade capability and business support capability.”

The CLOS architecture is renowned for its scalability and ability to build large, non-blocking switch fabrics. By dividing traffic switching into multiple stages, it ensures that sufficient internal bandwidth is available to handle traffic from any input port to any output port without contention, even under heavy load conditions. The “CELL-based” aspect refers to the fixed-size data units used for internal switching, which optimizes performance and predictability within the fabric. The separation of the forwarding plane (handled by the switch fabric and line cards) and the control plane (managed by dedicated management engines) is a cornerstone of modern high-reliability network devices. This separation means that intensive control plane operations (like routing table updates or SNMP queries) do not impact the data plane’s ability to forward traffic at line rate. Conversely, data plane issues are less likely to affect the stability of the control plane. This architectural choice provides sustained bandwidth upgrade capabilities and robust service support, forming a resilient and high-performance foundation for the data center network.

Unmatched Scalability and Port Density for Future Demands

In the rapidly evolving digital landscape, the ability to scale network capacity smoothly and cost-effectively is paramount. The RG-N18000-XH series is engineered with this imperative at its core, offering exceptional port density and a clear path towards next-generation interface speeds, ensuring that data centers can confidently meet both current and future bandwidth requirements.

The series provides remarkable flexibility in port configurations, accommodating a diverse mix of interface speeds. The RG-N18018-XH, with its 31RU height, stands as a capacity behemoth, capable of supporting up to 576 ports of 400G Ethernet, or alternatively, 768 ports of 40/100GE, or 768 ports of 10GE, all at line-rate performance. Its smaller sibling, the RG-N18010-XH, in a more compact 16RU chassis, offers substantial capacity as well, supporting up to 288 ports of 400G, or 384 ports of 40/100GE, or 384 ports of 10GE. This high density allows for the consolidation of network infrastructure, reducing the number of discrete devices required, which in turn can lead to savings in space, power, and cooling, as well as simplified management.

This impressive port density is realized through a selection of versatile line cards. For instance:

• The M18000XH-36QC-CES line card provides 36 ports of 400G Ethernet using QSFP-DD transceivers, ideal for high-bandwidth spine-leaf connections or DCI links.
• The M18000XH-48CQ-CES line card offers 48 ports of 100G Ethernet with QSFP28 interfaces, a common choice for interconnecting high-performance servers or aggregating leaf switches.
• For legacy or lower-bandwidth requirements, the M18000XH-48XS-DB line card delivers 48 ports of 10G Ethernet via SFP+ interfaces.

This range of line cards ensures that organizations can tailor their port configuration precisely to their needs, mixing and matching interface types as required. The design inherently supports “future evolution towards 800G rate ports,” a critical aspect for organizations looking to protect their infrastructure investments over the long term. As applications demand even greater bandwidth, the RG-N18000-XH chassis is ready to accommodate the next generation of high-speed optics and line cards, providing a seamless upgrade path without necessitating a complete forklift replacement of the core infrastructure. This forward-looking approach significantly enhances the total cost of ownership (TCO) and allows network architects to design with confidence, knowing their core platform can adapt to the relentless growth in data traffic. The system’s ability to provide such high port counts within standard rack unit footprints directly contributes to building more efficient and powerful network fabrics, capable of supporting the most demanding applications and services.

Enabling Agile and Scalable Data Center Fabrics with Overlay Technologies

Modern data centers require a level of agility and scalability that traditional Layer 2 networking technologies struggle to provide. Overlay networks, particularly those based on VXLAN (Virtual Extensible LAN), have emerged as a key enabler for building flexible, multi-tenant data center fabrics. The RG-N18000-XH series provides robust support for these technologies, empowering organizations to construct dynamic and scalable network environments.

A primary challenge in large data centers is the limitation of VLANs, which are capped at 4094 identifiers. This is often insufficient for multi-tenant environments or large-scale virtualized deployments. The RG-N18000-XH series addresses this directly by offering extensive VXLAN capabilities. The product specifications state it “can provide up to 16M VXLAN segments, meeting data center Overlay network construction needs, and solving the problem of insufficient VLANs and difficult-to-expand scale in traditional data center networks.” This massive increase in logical network segmentation allows for fine-grained isolation between tenants or applications, even across physically disparate parts of the data center. With VXLAN, Layer 2 segments can be extended over an underlying Layer 3 network, effectively decoupling the logical network topology from the physical infrastructure. This means that virtual machines or services can be migrated across the data center without needing to reconfigure IP addresses or be constrained by physical Layer 2 boundaries. As the documentation notes, “Based on the fundamental network built with RG-N18000-XH series switches, new subnets can be carved out using Overlay without changing the physical topology, and without considering the limitations of physical network IP addresses and broadcast domains.”

To further enhance VXLAN deployments, the RG-N18000-XH series supports Ethernet VPN (EVPN). EVPN serves as a more advanced control plane for VXLAN, offering significant advantages over traditional flood-and-learn mechanisms.

“The RG-N18000-XH series switches support the EVPN protocol, providing VTEP (VXLAN Tunnel Endpoint) auto-discovery and authentication. This can reduce VXLAN data plane flooding and avoid VXLAN’s dependency on underlying multicast deployment, simplifying VXLAN deployment and improving the construction efficiency of large Layer 2 networks, better meeting the requirements for large Layer 2 networks within data centers and Layer 2 interconnection for active-active data centers.”

By using BGP as the control plane for EVPN, VTEPs can automatically discover each other and exchange MAC address and IP address reachability information. This eliminates the need for widespread flooding of BUM (Broadcast, Unknown Unicast, Multicast) traffic within VXLAN segments, leading to more efficient use of network bandwidth. It also simplifies the configuration and management of VXLANs, as VTEPs do not need to be manually configured with information about all other VTEPs in the same VXLAN. This is particularly beneficial in large-scale deployments or in environments with dynamic virtual machine mobility. The support for EVPN facilitates the creation of highly scalable and resilient Layer 2 VPN services over an IP/MPLS core, making it an ideal solution for connecting multiple data centers or extending Layer 2 connectivity for disaster recovery and business continuity purposes.

Intelligent Networking with Advanced Routing Capabilities

Beyond raw switching capacity and overlay support, intelligent traffic steering and network programmability are becoming increasingly important. The RG-N18000-XH series incorporates advanced routing features, prominently featuring Segment Routing (SR), to enable more granular control over traffic paths and simplify network operations.

Segment Routing represents a significant evolution in how packets are forwarded through a network. It moves much of the path information from transit routers to the ingress node, simplifying the core network and allowing for more flexible and source-defined traffic engineering. The RG-N18000-XH series supports two key instantiations of this technology: SR-MPLS and SRv6.

For networks currently leveraging MPLS, SR-MPLS offers a streamlined approach. The documentation highlights:

“The RG-N18000-XH series switches support SR-MPLS features. SR-MPLS technology offers more flexible path selection; the traffic forwarding path can be specified at the Ingress node, satisfying user requirements for business path planning.”

With SR-MPLS, a path is defined as an ordered list of segments, where each segment can represent a topological instruction (e.g., “go to node X”) or a service instruction. The ingress router imposes an MPLS label stack corresponding to this segment list onto the packet. Transit routers simply process the top label, pop it, and forward based on the next label, without needing to maintain per-flow state. This simplifies the MPLS data plane and control plane, reduces the need for protocols like LDP or RSVP-TE for basic path establishment, and offers enhanced Traffic Engineering capabilities directly from the source node.

Looking towards the future, particularly in IPv6-centric environments, SRv6 provides an even more powerful and integrated solution.

“The RG-N18000-XH series switches support SRv6 features. SRv6 is a next-generation network protocol oriented towards the future, supporting seamless connection with IPv6 networks. It provides massive address space access, meeting the needs of massive tenants. Traffic forwarding paths can be flexibly defined according to a Segment List, satisfying user business path planning requirements.”

SRv6 leverages the IPv6 address architecture itself to encode segment information within an SRH (Segment Routing Header). This eliminates the need for MPLS in the data plane for segment routing, allowing SR capabilities to be deployed natively over IPv6 networks. The vast IPv6 address space allows for globally unique segment identifiers (SIDs), enabling highly scalable and flexible network programming. SRv6 can simplify network functions virtualization (NFV) service chaining, provide fine-grained traffic engineering, and support network slicing with greater ease than traditional methods. The ability to define paths as a sequence of SRv6 SIDs offers unprecedented control over how traffic traverses the network, allowing for policy-based routing, service insertion, and explicit path control for critical applications. The support for both SR-MPLS and SRv6 ensures that the RG-N18000-XH series can adapt to diverse network architectures and evolving industry standards, providing a foundation for more intelligent, programmable, and application-aware networks.

Ensuring Business Continuity with Data Center-Grade Reliability

In the mission-critical environment of a data center, network uptime is non-negotiable. The RG-N18000-XH series is engineered with a comprehensive suite of reliability features, designed to ensure business continuity and minimize service disruption. This commitment to high availability is evident in its redundant hardware design, rapid fault detection mechanisms, and sophisticated software-based resiliency protocols.

Hardware redundancy is fundamental to the resilient design of the RG-N18000-XH series. The switches support:

• N+M Switch Fabric Card Redundancy: Multiple switch fabric cards can be installed, with extras providing immediate failover capacity, ensuring sustained forwarding performance even if one or more fabric cards encounter issues.
• 1+1 Management Engine Redundancy: Dual management engines operate in an active-standby or load-sharing mode, allowing for hitless failover of the control plane.
• N+M Power Supply Redundancy: The chassis accommodates multiple power supply units (PSUs), exceeding the operational power demand, so the failure of one or more PSUs does not impact the switch’s operation. The power system also supports dual input feeds for enhanced power source diversity.
• 2+1 Fan Tray Redundancy: Multiple fan trays ensure optimal cooling, with redundant units capable of maintaining sufficient airflow if a fan tray fails.

All these critical components—power supplies, fan trays, management engines, and line cards—are hot-swappable, meaning they can be replaced without powering down the switch or interrupting network traffic. Furthermore, the “zero-backplane design avoids single points of failure” by eliminating a component that, in traditional designs, could bring down the entire chassis if it malfunctioned. The system also includes “over-current protection, over-voltage protection, and over-heat protection technologies.”

Rapid fault detection and recovery are equally crucial. The RG-N18000-XH series supports Bidirectional Forwarding Detection (BFD), a low-overhead, short-duration protocol for detecting failures in the path between two forwarding engines.

“The RG-N18000-XH series switches support BFD for VRRP/BGP/IS-IS/OSPF/RIP static routes, etc., for rapid fault detection. By linking with control plane protocols, it achieves rapid protection switching and fast convergence of protocols.”

BFD can detect link or node failures in milliseconds, far faster than typical routing protocol hello mechanisms. This rapid detection allows for near-instantaneous failover to redundant paths or backup devices, minimizing packet loss and service impact. Other reliability features include Non-Stop Routing (NSR) to maintain routing adjacencies during a control plane switchover, Device Link Detection Protocol (DLDP) to detect unidirectional link failures, Fast Reroute (FRR) for MPLS path protection, and Graceful Restart (GR) for common routing protocols like OSPF, IS-IS, and BGP, allowing a restarting router to continue forwarding traffic while its control plane recovers.

Fortified Security and Cost-Effective Interconnectivity

Data center security is a multi-faceted challenge, requiring protection at various layers. The RG-N18000-XH series integrates robust security features to safeguard network infrastructure and data traffic. Simultaneously, it offers innovative solutions for cost-effective, high-bandwidth Data Center Interconnect (DCI).

At the hardware level, the series supports MACsec (Media Access Control Security), providing Layer 2 data protection. As the documentation states, “RG-N18000-XH series switches support MACSec, enabling hardware-level data encryption functions. MACSec can provide users with MAC layer data encryption, data frame integrity checks, and data source authenticity verification, safeguarding user data.” This is particularly valuable for securing sensitive traffic between switches or from switches to trusted servers, ensuring confidentiality and integrity without impacting performance, thanks to hardware-based processing (on specific line cards, indicated by “#” in the PDF).

Beyond MACsec, a comprehensive suite of security mechanisms is available:

• NFPP (Network Foundation Protection Policy) and CPP (Control Plane Policing): These protect the switch’s CPU from being overwhelmed by excessive protocol traffic or denial-of-service attacks.
• Attack Prevention: Features to mitigate DDoS, ARP spoofing, and ICMP-based attacks.
• Access Control: Dynamic ARP Inspection (DAI), port security (limiting MAC addresses per port), IP Source Guard (preventing IP spoofing), and protected ports.
• uRPF (Unicast Reverse Path Forwarding): Helps prevent spoofed IP packets.
• Authentication and Authorization: RADIUS and TACACS+ for user login authentication, password security policies, hierarchical user management.
• Secure Management: SSHv2 for encrypted command-line access.
• Protocol Security: MD5 authentication for BGP, OSPF, IS-IS, and RIPv2 routing protocol updates.
• Traffic Control: Suppression of unknown unicast, broadcast, and multicast traffic to prevent storms.

For connecting data centers over distance, the RG-N18000-XH series offers a compelling solution with its support for 400G ZR and ZR+ optical modules.

“The RG-N18000-XH series switches support 400G ZR module interconnection, with transmission distances up to 80KM, simplifying long-distance DCI for data centers and significantly reducing DCI interconnection costs.”

The 400G ZR standard enables coherent optical transmission directly from switch ports over dense wavelength-division multiplexing (DWDM) systems, eliminating the need for separate, costly transponder equipment for many DCI applications. This simplifies the network architecture and dramatically lowers the cost per bit for inter-data center links. The future support for *400G-QDD-ZR+-SM1550 indicates even longer reach, “point-to-point unrepeatered transmission distance of 120km,” further expanding the possibilities for cost-effective, high-capacity DCI without intermediate amplification for many regional connections.

Innovative Green Technology for Sustainable Data Centers

Energy consumption is a significant operational expense and environmental concern for data centers. The RG-N18000-XH series incorporates multiple innovative green technologies designed to minimize power usage and improve thermal efficiency, contributing to more sustainable data center operations.

The core architectural choices play a vital role in energy efficiency. The “zero-backplane design brings direct airflow cooling functionality to the switch, perfectly matching the airflow path in data center rooms. This forms a high-speed, unimpeded airflow across the front and rear line cards, significantly improving heat dissipation efficiency.” This allows more cool air to enter the chassis for cooling, effectively lowering device temperature and preventing excessive power consumption due to overheating. The front panel itself is designed with “high-density perforations, increasing the air intake area at bends, achieving a panel perforation rate of up to 60%, effectively increasing air intake volume.”

Intelligent fan control further optimizes cooling and power use. “Fans support intelligent zoned speed adjustment + temperature-controlled speed adjustment, which can precisely control component temperatures, improving reliability by 30%.” Instead of fans running at full speed constantly, their speed is dynamically adjusted based on real-time temperature readings from various zones within the chassis. This ensures that components receive adequate cooling when needed, while reducing fan power consumption and acoustic noise during periods of lower load or cooler ambient temperatures.

Advanced thermal management materials and techniques also contribute to efficiency:

“The RG-N18000-XH series switches use vapor chamber and phase-change TIM (Thermal Interface Material) heat conduction technology. Compared to traditional heat pipe radiators and TIM material technology, this results in a temperature improvement of 15°C+ and a 20% increase in single-board reliability.”

Better heat transfer away from critical components like ASICs means they can operate at lower temperatures, which not only improves reliability and lifespan but can also reduce their power leakage and overall consumption.

Power supply efficiency is another key focus. The switches utilize “platinum-grade power supplies, with power conversion efficiency up to 94%.” High-efficiency PSUs waste less energy as heat during the AC-to-DC conversion process. Additionally, “400G cards adopt a PHY-less chip design, greatly reducing single-board power consumption,” and the system employs “low-impedance copper busbar design, with power distribution process losses less than 0.3%.” Every stage of power delivery and consumption is optimized to minimize waste, leading to a significant reduction in the overall power footprint of the switch. These combined efforts in airflow design, intelligent cooling, advanced thermal solutions, and power system efficiency make the RG-N18000-XH series a leader in energy-conscious core switching.
