Quidway® NetEngine 5000E Core Router
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 5
th
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.
