1.1 Introduction

This section describes the basic knowledge of the NE80 Series USR, including:

Overview

Hardware Architecture

Software Architecture

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 coversall-around services including enterprise interconnection, virtual leased line, IP telephone/

videoconferencing, content service, and security service. All these raise higher requirementsto 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, andabundant 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 thelow-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 newMANs.

The NE80 is the fifth-generation router, oriented to the carrier's backbone edge networks, thecore 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:

Gigabit Ethernet optical interface PIM PIC card

E1/T1 interface PIM card

E3 interface PIM card

T3 interface PIM card

Service Board

The NE80 provides Network Address Translation (NAT) service board. The NAT boardfeatures large capacity and high performance, and can support the translation between private

and public network addresses. The NAT board is used to solve the problems like the shortageof public network addresses and ensure the network security on the Internet.

For more information about the NE80 hardware system, refer to the Quidway NetEngiNE80Core Router Installation Manual.

1.1.3 Software Architecture

The software system of the NE80 adopts the architecture of two physically independentfunctional units, namely route control and packet forwarding. The architecture can improve

the stability and the processing performance of the system.

The system software consists of the following five parts: Network Management System(NMS), Routing Process System (RPS), Forwarding Support Unit (FSU), Express Forwarding

Unit (EFU), Driver (DRV), and the switch fabric monitoring module running on the MPUmanages the MPU and monitors its operation.

DRV modules are distributed in the RPS, FSU and EFU for driving the hardware of the MPU

and the LPU. Figure 1-1takes the NE80-8 for example to illustrate the NE80 softwarearchitecture.

As the control and management unit of the system, the RPS runs on the active and standbyMPUs and performs the following tasks:

Route control

The RPS calculates and maintains the routes. In addition, it generates the Forward

Information Base (FIB) table and delivers it to each LPU for IP forwarding.

Label control

The RPS distributes labels, sets up and maintains the Label Switch Paths (LSPs). In addition,it generates the FIB table and delivers it to each LPU for MPLS forwarding.

Traffic control

The RPS defines the traffic classification rules, configures the traffic parameters, configures

the queue resources and flow control parameters for Diff-Serv QoS.

Maintenance and management

The RPS maintains the devices, manages the network and devices, monitors the whole system,

diagnoses faults, and collects statistics for services.

Running on the CPU of the LPU, the FSU manages the service interfaces (configuring and

monitoring them), forwards data, controls the links, and negotiates the link parameters. Inaddition, the FSU can maintain and manage local devices for LPUs and provide some system

monitoring and diagnosis services.

In addition to fast forwarding of IP packets, the EFU can provide such QoS functions as

traffic classifying, traffic measuring, traffic policing, traffic shaping, traffic scheduling, and

congestion avoiding and controlling. It can implement Diff-Serv, firewall, and Class ofService (CoS) features according to different configuration requirements.

The Switch Fabric monitoring module monitors the internal switching network in the NE80

Series USR.

Implemented on the Huawei integrated network management platform, the NMS maintains

and controls devices uniformly.

The NE80 applies the Versatile Routing Platform (VRP) software system. As a versatileoperating system platform for Huawei's data communications products, the VRP realizes amodular architecture with IP services as the core. In addition to abundant functions and

features, the VRP provides some application-based capabilities such as scalability andflexibility.

With the TCP/IP protocol stack as the core, the VRP integrates multiple crucial technologies

for data communications such as routing, QoS, VPN, and security, thus providing excellentdata forwarding capability for the routing device.

The VRP provides consistent network, user, and management interfaces for various hardware

platforms and flexible solutions for users. The VRP is open to sustainable development, whichcan protect carriers' investment to its maximum extent.

1.2 Characteristics of the NE80

This section includes:

Support for Flattened Network Architecture

Line-Speed Forwarding

Multiple Interfaces

Carrier-Class Availability

Rich Services

Perfect Diff-Serv/QoS

Excellent Security Mechanism

Practical NMS

Flexible Networking Capabilities

1.2.1 Support for Flattened Network Architecture

Modern telecom network has a hierarchical architecture, within which data services are

typically provided after they are processed by four vertical function layers. This classicalarchitecture will still exist for a certain period. This architecture reveals its deficiency

increasingly because IP services are becoming leading services in the network. Flattening ofthe network architecture is the trend with the development of technologies and the change of

services.

The devices at the core layer of the telecom network are used with high efficiency because agreat amount of user data is processed there. Whereas, the devices out of the core layer are

used less efficiently due to sparse distribution of access users. Therefore, a flattened IPnetwork architecture should be employed if possible. Fewer network layers help carriers

utilize network devices more efficiently and slash the maintenance and management cost. Theoperable and manageable IP network becomes the development trend of MANs and enterprise

networks at present.

The flattened network architecture puts forward higher requirements on the devices at theconvergence layer, that is, they need function as both access devices and core devices. The

NE80 is such a product that implements various services due to its abundant service features,excellent hardware platform, and high reliability. For example, the NE80 can directly connect

downlink with Gigabit Ethernet switches or dedicated access devices, and uplink withprovincial backbone or national backbone networks. In addition, the NE80 can form a ring

network through Resilient Packet Ring (RPR) or connect to core devices through dual homing.

In this case, the NE80 may reduce the levels of the network construction to achieve theflattened network, which improves the service quality and optimizes the network architecture.

1.2.2 Line-Speed Forwarding

The NE80 supports the IPv4/MPLS distributed forwarding at the line speed. Thus the NE80

can meet the bandwidth requirements when it is used as the Point of Presence (POP), theconvergence layer, or the switching node on the backbone networks.

1.2.3 Multiple Interfaces

At present, the NE80 provides the Fast Ethernet (FE) interface, Gigabit Ethernet (GE)interface, E1/cE1 interface, E3 interface, T3 interface, Packet over SDH/SONET (POS)

interface, channelized POS (cPOS) interface, Asynchronous Transfer Mode (ATM) interface,and RPR interface with high interface density. Users can select the cards flexibly as required

to meet the requirements for different networking solutions and network expansion.

1.2.4 Carrier-Class Availability

The key parts of the NE80 adopt redundant hot backup design, including system control, data

exchange, route processing system, internal management bus and power supply. All thecomponents are hot swappable. Thus, the router can meet the high reliability requirement

when it is used as the POP, the convergence layer, or the switching node on the backbonenetworks

1.2.5 Rich Services

The IP multicast forwarding feature provides the foundation for carriers to carry on variousnetwork voice and video services (Web TV, E-learning, telemedicine and video conference).

With the rich routing features, the router is adaptable to complex environments.

The policy service mechanism enables the system to have powerful performance optimization

capability, satisfactory attack defense capability and QoS guarantee while ensuring the linerate processing and forwarding capability.

The application of the MPLS VPN service guarantees the delivery of services of carriers

using networks more economically and rationally with no need to increase the bandwidth.

The application of the NAT service supports addressing with public and private networkaddresses mixed in the MAN to save IP addresses. In this way, the shortage of

public IP addresses can be solved.
