services are not affected. This ensures continuous evolution and expansion of the customer
service system.
Comprehensive Virtualization Capabilities Implement Simple, Efficient
Networking
VS Implements On-demand Resource Sharing
•
Highest device virtualization capability: The CE12800 uses Virtual System (VS) technology to
provide an industry-leading virtualization capability that enables one switch to be virtualized into
as many as sixteen logical switches. This 1:16 ratio enables one core switch to manage services
for an enterprise's multiple service areas such as production, office, and DMZ, or for multiple
tenants.
•
Higher security and reliability: VS technology divides a network into separate logical areas
for service isolation. The failure of one virtual switch does not affect other virtual switches,
enhancing network security.
•
Lower CAPEX: VS technology improves the use efficiency of physical devices by implementing ondemand resource allocation. This ensures network scalability and reduces investment in devices.
•
Lower OPEX: Using one physical device to implement multiple logical devices saves space in a
data center equipment room and reduces the cost of device maintenance.
CSS Simplifies Network Management
2
•
The CE12800 uses industry-leading CSS technology, which can virtualize multiple physical
switches into one logical switch to facilitate network management and improve reliability.
•
The CE12800 provides the dedicated system inter-connect port and separates the control
channel from the service channel, improving reliability.
•
The CE12800 provides a cluster bandwidth of 1.6 Tbit/s. This super-high bandwidth prevents
traffic bottlenecks on data center networks.
•
The CE12800 switches establish a cluster using service ports with distances of up to 80 km
between cluster member switches.
•
The CE12800 uses CSS+VS synergy technology to turn a network into a resource pool so that
network resources can be allocated on demand. On-demand resource allocation is ideal for the
cloud-computing service model.

Large-Scale Routing Bridge Supports Flexible Service Deployment
•
The CE12800 series switches support Transparent Interconnection of Lots of Links (TRILL), a
standard IETF protocol. The TRILL protocol helps build a large Layer 2 network with more than
500 nodes, which permits flexible service deployments and Virtual Machine (VM) migrations. A
TRILL network can use 10GE/GE servers.
•
The TRILL protocol uses a routing mechanism similar to IS-IS and sets a limited Time-to-Live (TTL)
value in packets to prevent Layer 2 loops. This significantly improves network stability and speeds
up network convergence.
•
On a TRILL network, all data flows are forwarded quickly using Shortest Path First (SPF) and
Equal-cost Multi-path (ECMP) routing. SPF and ECMP avoid the problem of suboptimal path
selection in the Spanning Tree Protocol (STP) and increase link bandwidth efficiency to 100
percent.
•
The CE12800 supports up to 32 TRILL-based Layer 2 equal-cost paths, greatly improving links'
load-balancing capabilities. The network's fat-tree architecture supports easy expansion.
EVN Supports Resource Sharing Across Data Centers
•
The Ethernet Virtual Network (EVN) implements inter-data center Layer 2 interconnection across
the IP WAN, and integrates multiple data centers into a large IT resource pool. VMs can migrate
between data centers. EVN supports Layer 2 interconnection of a maximum of 32 data centers,
which enable scalability that is 5 times higher than the industry. EVN combines the advantages of
the Border Gateway Protocol (BGP) and Virtual Extensible LAN (VXLAN) to provide high scalability
and highly efficient use of bandwidth.
•
High scalability: Based on BGP at the control plane, the CE12800 supports millions of MAC
addresses and routes, 32K tenants, and 256K VMs.
•
Highly efficient bandwidth usage: The forwarding plane uses VXLAN encapsulation. Flow-based
load balancing is implemented on the entire network, which optimizes bandwidth usage.
nCenter Implements Fast VM Migration
•
The CE12800 works with Huawei's nCenter automated network management platform to permit
network policies to be dynamically deployed on the CE12800. nCenter also supports online VM
migration.
•
nCenter delivers network policies through high-speed RADIUS interfaces. Its online VM migration
is 10 to 20 times the rate of other industry platforms, enabling large-scale VM migrations.
•
nCenter is based on open APIs and is compatible with all major virtualization platforms including
VMware.
Fully Programmable Switch Permits Agile Service Provisioning
ENP Implements Programmability at the Forwarding Plane
•
The CE12800 is based on Huawei's innovative, programmable Ethernet Network Processor (ENP).
The high-performance 480 Gbit/s ENP card implements openness and definition capabilities for
the first time at the forwarding plane on data center networks.
•
The ENP card defines network functions through software and extends network functions. When
new services are provisioned, there is no need to invest in replacement hardware.
•
The ENP card reduces service provisioning from two years to six months - an improvement of
four times over current industry capabilities that help customers to quickly implement service
innovations.
OPS Implements Programmability at the Control Plane
•
The CE12800 uses the Open Programmability System (OPS) embedded in the VRP8 software
platform to provide programmability at the control plane.

CloudEngine
12800
•
The OPS provides open APIs. APIs can be integrated with mainstream cloud platforms (including
commercial and open cloud platforms) and third-party controllers. The OPS enables services to
be flexibly customized and provides automatic management.
•
Users or third-party developers can use open APIs to develop and deploy specialized network
management policies to implement extension of fast service functions, automatic deployment,
and intelligent management. The OPS also implements automatic operation and maintenance,
and reduces management costs.
•
The OPS provides seamless integration of data center service and network in addition to a
service-oriented, Software-Defined Network (SDN).
Virtualized Gateway Achieves Fast Service Deployment
•
The CE12800 can work with a mainstream virtualization platform. As the high-performance,
hardware gateway of an overlay network (NVGRE/VXLAN), a CE series switch can support more
than 16M tenants.
•
The CE12800 can connect to a cloud platform through an open API to provide unified
management of software and hardware networks.
•
This function implements fast service deployment without changing the customer network. It
also protects customer investments.
ZTP Implements Zero-Configuration Deployment
•
The CE12800 supports Zero Touch Provisioning (ZTP). ZTP enables the CE12800 to automatically
obtain and load version files from a USB flash drive or file server, freeing network engineers from
onsite configuration or deployment. ZTP reduces labor costs and improves device deployment
efficiency.
•
ZTP provides built-in scripts for users through open APIs. Data center personnel can use the
programming language they are familiar with, such as Python, to provide unified configuration of
network devices.
•
ZTP decouples configuration time of new devices from device quantity and area distribution,
which improves service provisioning efficiency.
Advanced Architecture Ensures Industry-Leading Network Quality
High-Performance, Non-blocking Switching Architecture
4
•
The CE12800's non-blocking switching architecture includes an orthogonal switch fabric design,
Clos architecture, cell switching, Virtual Output Queuing (VOQ), and a super-large buffer.
•
Orthogonal switch fabric design: CE12800 service line cards and switch fabric units (SFUs) use
an orthogonal design in which service traffic between line cards is directly sent to the SFUs
through orthogonal connectors. This approach reduces backplane cabling and minimizes signal
attenuation. The orthogonal design can support signal rates as high as 25 Gbit/s per Serdes,
which is 2.5 times the industry average. This design greatly improves system bandwidth and
evolution capabilities, enabling the system switching capacity to scale to more than 100 Tbit/s.
•
Clos architecture: The CE12800's three-level Clos architecture permits flexible expansion of switch
fabric capacity. The architecture uses Variable Size Cell (VSC) and provides dynamic routing. Load
balancing among multiple switch fabrics prevents the switching matrix from being blocked and
easily copes with complex, volatile traffic in data centers.
•
VOQ: The CE12800 supports 96,000 VOQ queues that implement fine-grained Quality of Service
(QoS) based on the switch fabrics. With the VOQ mechanism and super-large buffer on inbound
interfaces, the CE12800 creates independent VOQ queues on inbound interfaces to perform endto-end flow control on traffic destined for different outbound interfaces. This method ensures
unified service scheduling and sequenced forwarding and implements non-blocking switching.

Highly Reliable Industry-grade Hardware Architecture
•
Hot backup of five key components: Main Processing Units (MPUs) and Centralized Monitoring
Unit (CMUs) work in 1+1 hot backup mode. SFUs work in N+M hot backup mode. Power
supplies support dual inputs and N+N backup and have their own fans. Both fan trays work in
1+1 backup mode; each fan tray has two counter-rotating fans working in 1+1 backup mode,
ensuring efficient heat dissipation.
•
Redundancy of three types of major buses: Monitoring, management, and data buses all work in
1+1 backup mode. Bus redundancy ensures reliable signal transmission.
•
Independent triple-plane design: The independent control, data, and monitoring planes of the
CE12800 improve system reliability and ensure service continuity.
High-Performance VRP8 Software Architecture
•
The CE12800 takes advantage of Huawei's next-generation VRP8, a high-performance, highly
reliable modular software platform that provides continuous services.
•
Fine-grained distributed architecture: VRP8, the industry's high-end software platform, uses
a fine-grained, fully distributed architecture that can process network protocols and services
concurrently using multiple instances. This architecture takes full advantage of multi-core/multiCPU processes to maximize performance and reliability.
•
Highly reliable In-Service Software Upgrade (ISSU): VRP8 supports ISSU.
Pioneering Energy-saving Technologies
Strict Front-to-Back Airflow Design
•
The CE12800 uses a patented front-to-back airflow design that isolates cold air channels from
hot air channels. This design meets heat dissipation requirements in data center equipment
rooms.
•
Line cards and the switching network use independent airflow channels, which solve the
problems of mixing hot and cold air and cascade heating, and effectively reduce energy
consumption in equipment rooms.
•
Each fan tray has two counter-rotating fans, ensuring efficient heat dissipation.
•
The fan speed in each area can be dynamically adjusted based on the workload of line cards in
the area. This on-demand cooling design lowers power consumption and reduces noise.
Low Power Consumption (5 W/10GE)
•
The CE12800 uses innovative energy saving technologies. Each 10GE port consumes only 5 W
power, which is half the industry standard. It greatly reduces power consumption in the data
center equipment room.
•
Miercom has performed a series of strict tests for the CE12800, proving its low power
consumption.
•
Miercom test report: http://enterprise.huawei.com/ilink/cnenterprise/download/HW_200123.
Efficient, Intelligent Power Supply System
•
The CE12800 incorporates the industry's most efficient digital power modules, which provide
power efficiency of 96 percent.
•
The power supply system measures power consumption in real time and puts one or more power
modules into sleep mode when system power demands are low.
•
The CE12800 can save energy dynamically by adjusting the power consumption of components
to adapt to changes in service traffic volume.
