1 Overview
ZXR10 ZSR V2 is ZTE’s intelligent multiservice router integrating routing, switching,
wireless, security and VPN. The modular and scalable system structure builds intelligent,
efficient, reliable, flexible and maintainable network.
ZXR10 ZSR V2 series router includes 1800-2S/2S(G)/2S(W), 2800-4, 3800-8, 1800-2E
/2E(G)and 2800-3E/3E(G). They can meet different market demands. Their forwarding
performance ranges from 1Mpps to 5Mpps. They can be applied to VIP access, DCN,
campus network, enterprise network egress gateway, enterprise headquarter/branch
access, mobile office, industry network convergence/access, etc.
The appearance of each product is shown as below:

2 Highlights
2.1 Strong performance, no bottleneck for network
access
The rise of enterprise application content and network data traffic and the appearance of
video-conference, remote teaching and remote data disaster recovery backup lead to
higher performance requirements for node equipment processing network data.
High-performance multi-core processor + Smart Switching Engine (SSE) ensure

ZXR10 ZSR V2 Series Router Product Description
8ZTE Confidential & Proprietary
high-performance protocol processing and management control processing as well
as L2/L3 high-speed forwarding of data, increasing the overall system performance
by 10 times than the previous generation of access router. The multilayer distributed
forwarding allocates system resources reasonably in system multiservice overlay to
assure excellent forwarding performance. Single slot has the bus bandwidth of up to
10Gbps.
Support high-speed interface of GE, FE, E1, POS, CPOS, xDSL,
Synchronous/asynchronous serial wire port and 3G/LTE, Wi-Fi wireless port, and the
device Integrated industry's largest fixed-Gigabit interfaces, which can be used as
WAN or LAN access, providing a complete and flexible access capability.
The perfect high reliability design. AC/DC power supply 1+1 hybrid redundancy.
Power supply, fans and interface boards hot-swappable. The software modular
design, which can overlay new features flexibility and improve system stability and
flexibility. Perfect OAM detection mechanisms and BFD for everything, FRR, VRRP,
links bundled and other rich reliability technologies to enhance service reliability.
Control plane security technologies include classification of the control plane packets,
multi-level speed restrictions, multi-level scheduling, traffic suppression, protocol
white name, protocol authentication, anti-DDOS attack mechanism and attack trace
functions. The greatest degree to ensure the safety of equipment itself.
Strong ACL, excellent L2/L3 ACL mixed processing algorithms, up to 8K ACLs
capacity (all overlay loads scene, the system performance degradation is less than
30%) and humanization ACL log statistics management function helps users to
easily achieve fine management of various services.
Compact design, 1800-2S adopts the desktop design. 2800-4 and 3800-8 adopt the
front cabling design where operation and maintenance can be fulfilled at single side.
They can be installed into 300mm-deep cabinet to saving the space in equipment
room, and or into outdoor cabinet, vehicle equipment, BS and office locker to cut
O&M cost.
