1.1.1 Overview
Nowadays the IP Metropolitan Area Network (MAN) has developed into a new stage. It is no
longer limited to merely supplying individual broadband internet access services, but covers
all-around services including enterprise interconnection, virtual leased line, IP telephone/
videoconferencing, content service, and security service. All these raise higher requirements
to MAN devices.
According to the development of IP MANs, Huawei launches the NE80 Series USR. The
NE80 has the following features: large capacity, high performance, high reliability, and
abundant service capability required by MANs, such as line-speed forwarding on high-speed
interface, Ethernet switching, Multi-Protocol Label Switching Virtual Private Network
(MPLS VPN), perfect Quality of Service (QoS) mechanism and carrier-class reliability, which
provide abundant service processing capabilities and flexible networking capability.
The NE80 incorporates the powerful IP service processing capability of routers and the
low-cost Ethernet switching capability of Layer 3 Ethernet switches, and serves as a powerful
core router or a Layer 3 Ethernet switch. Therefore, the NE80 is an optimal choice for new
MANs.
The NE80 is the fifth-generation router, oriented to the carrier's backbone edge networks, the
core and the convergence layer of MANs, and networks of various industries and enterprises.
The NE80 enriches and perfects the high-end router series of Huawei, for it provides
cost-effective network solutions, and offers more choices.
1.1.2 Hardware Architecture
The boards of the NE80 are classified into Switch and Routing Unit (MPU) and Line Card
(LC). The LCs include Line Processing Unit (LPU), Flexible Card Line Processing Unit
(LPUF) and service board.
MPU
The MPU completes such functions as system management, route control, data exchange, and
stratum-3 clock.
The NE80 have two MPUs for 1 + 1 redundancy. When one MPU fails, the service will be
automatically switched to the other MPU.
LPU
LPUs implement the interconnection and data forwarding with other devices. The NE80
supports the following LPUs:
