High Efficiency, Bearing More Value

---ZTE ZXR10 8900 Series Terabit MPLS Routing Switch

Overview

ZXR10 8900 Series Terabit MPLS Routing Switches are high-end modular switches featuring big

switching capacity, full L2/L3/MPLS service capability, high-performance, superior reliability and

enhanced security. ZXR10 8900 is designed for the core/aggregation layer of the Metro network or

Datacenter.

ZXR10 8900 includes four models: ZXR10 8902, 8905, 8908 and 8912. Multiple kinds of line card

modules are available for the 8900 switching platform while one specific interface module can be

equipped on any of these four switch types, providing maximum flexibility and protecting hardware

investment for users.

Advanced Features

Robust Hardware Architecture

ZXR10 8900 adopts a large-capacity and high-speed serial bus backplane to connect the main

control board with all service line cards. The control module and switch matrix are integrated in one

main-control unit and can provide 1:1 redundancy. A large-capacity switch matrix is used to

guarantee sufficient switching capacity for the system. The control board uses a high-performance

CPU and large memory to ensure adequate computing power and storage space for speedy

protocol processing and quick look up in big table structures. Each line card provides packet

processing capability at wire speed through ASIC and offers 10G, 1G and 100M interfaces to

different services.

High Performance Software Platform

For software, the ROS operating system of ZXR10 8900 is a multi-task, real-time operating system.

It is responsible to manage the hardware architecture of the entire routing switch, providing a

unified operation platform for the applications. Based on the VxWorks kernel, task scheduling,

process collaboration, data-structure synchronization, memory management, and time

management can be well-implemented.

With a software platform featuring high efficiency and loose-coupling relationship between different

functional modules 8900 would bring maximum reliability for user, especially when it is deployed at

a critical network position.

Large Capacity/High Performance

Targeting for the aggregation or core layer of the network, ZXR10 8900 is designed to have big

switching capacity and high performance for high quality multi-service bearing purpose.

Taken ZXR10 8912 as an example, ZXR10 8912 supports up to 1152Gbps non-blocking switching

capability, or 857Mpps packet forwarding capability; it has 384K routing table depth, 512K MAC

table depth and can provide 4096 VLAN , 10K ACL per interface module.

ZXR10 8900 also supports extremely abundant types of line cards. Users can choose from a wide

selection of line cards to meet their unique demands of interfaces, fulfill their customized

requirements for their networks, and protect their network investment at the same time.

Powerful Service Bearing Capability

ZXR10 8900 supports L2/L3/L4 full-rate switching and full metro Ethernet service bearing

capabilities, including MPLS and multicast, adding more new value to the network when deployed

at core/convergence layer of the network. It also supports hardware-based Qos mechanism like

traffic accounting, classification, rate limit and queue scheduling to help users deploy value-added

services.

Excellent Security

ZXR10 8900 supports complete ACL security filtering mechanisms. It's able to provide security

control based on MAC/IP address or application layer port number. Meanwhile, it also supports

uRPF, anti-DDOS attack, SSH2.0 security management, 802.1x access authentication, port

number and IP address binding, etc.

Comprehensive MPLS Related Features

ZXR10 8900 fully supports L2 MPLS VPN based on draft Martini, and L3 MPLS VPN based on

RFC2547. The standard realization of L2 VPN and L3 VPN enables internetworking of 8900 with

devices from other vendors. The equipment also supports MPLS-TE to better utilize network

bandwidth and enhance network reliability.

Carrier-class Reliability to Ensure Ever-online Services

Key modules of ZXR10 8900, such as system main-control units and power supply modules all

adopt 1:1 backup design.

When deployed in layer 2 environment, ZESR/ZESR+ (ZTE Ethernet Smart Ring) and ZESS (ZTE

Ethernet Smart Switching) can be used to implement fast switchover in case of single point failure.

ZXR10 8900 supports both close ring ZESR and open ring ZESR+, which are very good network

redundancy solutions in ring topology networks.

ZESS is a very simple yet effective means to realize dual-homing purpose.

Compared with STP, the biggest advantage is that the link will switch and recover quickly when

one way is disconnected and the time needed for switchover is less than 50ms. ZESR/ZESR+

supports VLAN load balancing to enable efficient utilization of redundant links.

Service reliability requirements can be met with full support for all kinds of redundancy/backup

mechanisms including VRRP, LACP, FRR, NSF and BFD.

Excellent Operation and Maintenance Design

The ever-accelerating growth of network service makes fast deployment of network service

become more and more important. ZXR10 8900 can be used together with ZTE's unified network

management platform to provide customers with service configuration, management, problem

diagnosis, and performance monitoring means.

Customers can get to know the network operating status at any time. The deep inspection carried

out by intelligent OAM tools simplifies trouble-shooting and makes network management much

easier.
