The CR19000 core router series (hereinafter referred to as the CR19000) is a set of new-generation core routers developed for service provider-level applications. It can be deployed as service providers' backbone nodes and MAN core nodes, or data centers backbone interconnection nodes. The CLOS architecture, cutting-edge optical connection technology, and Comware V7 operating system enables the CR19000 to deliver extraordinary availability and compatibility, making it an ideal choice for service providers.
The CR19000 router adopts the most advanced fourth-generation non-blocking CLOS switching architecture, which enables data to be transmitted at a super high speed with low latency. Support for variable-length cell switching significantly improves operation efficiency of the overall cluster.
On a single CR19000 with 1800G capacity on each slot, each port can provide a capacity as high as 400Gbps. The router supports a maximum of 360 100G ports and this number will be continuously increased.
The CR19000 supports multiple cluster modes, such as back-to-back, 2+6, and 3+12, and supports cascade of up to 12 chassis. Smooth expansion from a single chassis to a cluster protects users' investment
With full support for SDN, the CR19000 provides various protocol interfaces for collaboration with external systems and can communicate comprehensively with SDN controllers. This enables users to precisely control network resources on demand and greatly improves network operation efficiency.
The CR19000 provides comprehensive high availability performance by using the following methods:
Advanced distributed architecture—With separated routing, service, and switching engines, the failure of a single hardware component does not affect the operation of the whole system. The separation of control plane and service plane prevents service processing and system control from affecting each other and ensures service continuity during active/standby switchover. Support for N+M redundancy of switching fabric modules guarantees line-speed traffic forwarding during switching fabric module replacement.
Comware 7-based operating system—The control plane of the OS adopts multi cores and the Symmetrical Multi-Processing (SMP) technology to provide separate processing and running space for each software module, enabling dynamic loading and independent upgrade. Support for running specific processes on the dedicated CPU set, together with preemptive scheduling and priority settings, guarantees resources for critical services when the CPU usage is high. Distributed computing and refined management further improves system stability.
Abundant availability features—The CR19000 supports abundant availability features, including hot patching, link detection protocols NSR, GR, BFD, and NQA, fast convergence protocols IP FRR and LDP FRR, and Embedded Automation Architecture (EAA). With all these features, the CR19000 is able to provide ultra-large service capacity and ultra-fast service convergence as required by service providers in large-scale deployment.
The industry-leading environment-friendly and sustainable design greatly increases the energy efficiency and ensures smooth upgrade.
The router uses cut-through ventilation aisles, which brings much higher cooling efficiency than the traditional U-shaped, Z-shaped, or C-shaped air isles. This design enables the air to flow through the router with almost no loss in air volume and speed and can fully satisfy the cooling requirements of core network devices with continuously increasing capacity.
With the smart micro-module heat dissipation system, the router perfectly balances ventilation and power consumption. The cluster system can intelligently adjust the fan speed based on the hotspot information to meet the overall ventilation requirements.
