System Architecture
Overview
The Quidway® NetEngine 5000E core router (hereinafter referred to as "NE5000E") is a top-level router launched by Huawei in orientation to Internet backbone node, MAN core node and data interconnection center node. The NE5000E inherits the design philosophy of the 5th generation router. Based on advanced network processor technology, ASIC technology, IPv6 technology and optical backplane interconnection technology, the NE5000E adopts a distributed and scalable design and achieves a mass switching capacity and super high forwarding performance, fully satisfying bandwidth performance, QoS and service provisioning capability requirements of the new generation Internet.
The NE5000E has a switching capacity of 2.56 Tbps and an interface capacity of 1.28 Tbps, supporting high-density 10G/40G interfaces and delivering a forwarding performance of up to 1600 Mpps. The NE5000E is scalable through interconnection of optical backplanes, and also supports multi-chassis cascading, improving the interface capacity and system performance greatly. The NE5000E has 22 slots: two for MPUs (1:1 backup), four for SFUs (1+3 backup) and 16 service slots.
Architecture
The NE5000E is based on full-distributed hardware forwarding and non-blocking CROSSBAR switching technology and configured with three sets of built-in buses: monitor bus, management bus, and high-speed data bus.The interface boards of the NE5000E adopt advanced ASIC and network processor technologies to implement high-speed service processing.

NE5000E hardware architecture
The NE5000E has the following major boards: Main Processing Unit (MPU), Switch Fabric Unit (SFU) and multiple Line Processing Units (LPUs). The key parts such as MPU, SFU, fan and power supply adopt redundancy design, improving the reliability of the whole system. The interface types of LPUs include GE, 10GE, 10G POS, 2.5G POS, and so on.
Logically, the NE5000E can be divided into three planes: data plane, control & management plane, and monitoring plane. The three planes provide the following functions:

Logical architecture of NE5000E
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.
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.
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.
