Overview
The Quidway

NetEngine 40E-8 Core Router (“NE40E” hereinafter) is an enhanced high-end
network product of the NE series launched by Huawei. It is mainly applied in IP backbone networks,
IP MANs and the edge of other large IP networks. It can provide wire-speed 10G interfaces and can
be networked with core routers of the NE5000E and NE80E series to form an IP network solution of
integral architecture and clear hierarchy.
In addition to the powerful IP service processing capabilities of core routers, the NE40E integrates
Layer 3 (L3) Ethernet switching capabilities and provides abundant IP edge service features,
including Ethernet switching, PE, tunneling and stream queuing. It can serve as a service router of
the MAN to fully satisfy the development requirements of MAN IP and Ethernet services.
The NE40E provides a switching capacity of 640 Gbps, an interface capacity of 160Gbps and a
packet forwarding rate of 200Mpps. It may provide higher capacity in subsequent versions. It has
altogether 12 slots. Among these slots, two are for the SRU (1:1 backup), two are for the SFU
(working with two SRU boards to provide 1+3 backup for the switching network) and eight are
service slots.
System Architecture
Based on the distributed hardware forwarding and non-blocking switching technology, the NE40E
employs the industry-leading high-performance Network Processors (NPs). It provides carrier-class
reliability, wire-speed forwarding performance, complete QoS mechanism, powerful service
processing capabilities and high scalability. It pushes the IP network towards broadband, security,
service and intelligence.
