Quidway® NetEngine 80 Core Router
System Architecture
Overview
The Quidway® NetEngine 80 core router (abbreviated to NE80) is a 5th generation high-end router
product launched by Huawei in orientation to carrier-class operation networks and backbone
networks. It is mainly applied in the key positions of IP backbone networks, IP MANs and various
large-scale IP networks. The NE80 provides multiple network solutions, and can also work with
other Huawei products to provide integrated solutions.
The NE80 has the switching capacity of 128 Gbps, the backplane capacity of 256 Gbps, and the
packet forwarding rate of 96 Mpps. The NE80 has 20 slots: two for MPUs (1:1 backup), two for
NETBs (1:1 backup) and 16 service slots, providing line cards and service interfaces ranging from
64 Kbps to 2.5 Gbps.
Architecture
The NE80 is based on a distributed forwarding architecture and adopts the passive backplane
design. All Line Processing Units (LPUs) are configured with independent CPU, NP and Physical
Interface Card (PIC), greatly improving the processing performance and scalability of the whole
system.

The NE80 provides the following major boards: Main Processing Unit (MPU), Switching Network
Board (NETB), Clock Board (CLK) and various LPUs. The key parts such as MPU, NETB/CLK, fan
and power supply adopt redundancy design, improving the reliability of the whole system. The
interface types of the LPU include Ethernet interfaces, E1, POS, CPOS, ATM, RPR, and NAT.
The whole system is divided up into three logical planes: forwarding plane, control plan and
monitoring plane. The NE80 realizes forwarding and control separation as well as routing and
switching separation.
z The data plane completes high-speed data packet processing and internal non-blocking
switching, including packet encapsulation/decapsulation, IPv4/MPLS forwarding processing,
QoS and packet scheduling, internal high speed switching and various statistics.
z The control and management plane completes system control and management functions. It is
the nerve center of the entire system. The control and management unit completes functions
such as protocol and signaling processing, system status configuration and maintenance
management as well as system status reporting and control.
z The monitoring plane independently completes system environment monitoring, including
voltage detection, system power on/off control, temperature detection and fan control to
ensure the safe and stable operation of the system. It isolates the fault in time when a unit is
faulty, thus guaranteeing the normal operation of the other system components.
