Chapter 1 Router Overview

1.1 Introduction

H3C AR 46 Series Routers are next generation high-performance edge routers that

H3C Technology solely developed. They provide high forwarding performance and a

broad service range. The series supports flexible interface cards (FICs), hot swappable

fan modules and power supply units (PSUs) in 1+1 redundancy. Along with the NE

Series Routers, the AR 46 series provides complete network solutions for service

providers and enterprises.

The following are the major features of the AR 46 series.

I. Abundant FIC options

The H3C AR 46 series are available with a wide range of FICs. This allows for great

flexibility and thus protects user investment.

II. Ethernet access

The electrical and fiber (multi-mode and single-mode) Ethernet FICs support PPPoE

and PPPoEoA, and can offer authentication, authorization, and accounting (AAA)

services for Ethernet access. These cards are suitable for providing broadband access,

for example, for government agencies and enterprises.

III. ATM and DSL

Digital subscriber line (DSL) is a simple but highly efficient broadband technology which

achieves great data transmission capacity over existing copper wiring by using the

digital code modulation technology. Installed with an ADSL or G.HSDSL card, the AR 46

series can connect medium-to-small-sized enterprises to digital subscriber line access

multiplexer (DSLAM) equipment across a public switched telephone network (PSTN) to

the Internet.

Asynchronous transfer mode (ATM) transmits, multiplexes, and switches information in

cells. In addition to DSL cards, the AR 46 series is available with these ATM cards: 25

Mbps, 155 Mbps, E3/T3, and IMA-E1/T1. The cards support ATM adaptation layer type

5 (AAL5) and offer traffic services such as constant bit rate (CBR), variable bit rate

(VBR) and unspecified bit rate (UBR). They are well-suited to transfer large packets

and provide high-speed data services. A small to medium-sized enterprise can use

them to connect its network to an ATM network.

IV. MPLS

Multiprotocol label switching (MPLS), a combination of IP and ATM technologies,

replaces the IP header with a short and length-fixed label as traffic identifier, based on

H3C AR 46 Series Routers Installation Manual Chapter 1 Router Overview

1-2

which each router makes forwarding decision. It thus provides faster forwarding speed,

gets support from IP routing and control protocols, and accommodates to emerging

applications. In an MPLS network, labeled packets are transmitted along a label

switched path (LSP) formed by label switching routers. As an LSP is virtually a tunnel

across the public network, MPLS has an intrinsic advantage in terms of VPN

implementation. The AR 46 series usually acts as label edge routers (LERs) to connect

an MPLS domain with a non-MPLS domain or connect MPLS domains of different

service providers, implementing service classification, label distribution, encapsulation,

and multi-label peel-off.

V. Data security and reliability

The following are the data security and reliability features that the AR 46 series

supports:

zNAT. Besides some basic functions, NAT can limit concurrent connections to a

single user, and thus alleviate negative impact caused by malicious resources

occupation without affecting the normal network applications. In addition, NAT of

the AR 46 series also provides the application layer gateway (ALG) function

specific to FTP and ICMP.

zIdentity authentication protocols such as PAP, CHAP, data RADIUS, VoIP

RADIUS, and TACACS.

zPacket filter and application specific packet filter (ASPF), which fend off external

attacks.

zVPN (including GRE, L2TP, DVPN, and MPLS L2/L3 VPN) and the technologies

of IPSec and IKE. They can ensure security of private networks in an Internet

environment.

zBackup center and virtual router redundancy protocol (VRRP). By providing a

backup scheme in case of communication line or device failures, they enhance

robustness and reliability of networks. Backup center also supports backup load

sharing.

zHot swappable fans, interface cards, and PSUs to ensure high reliability.

VI. Online software upgrading

You are allowed to upgrade application and Boot ROM programs, and add new

features and functions on line as needed.

VII. Abundant fault isolation methods

zYou are available with the means to monitor the states of system configurations,

system service channels, and system resources, as well as fault indication via

console and network management host. In addition, logging function is provided

for recording and outputting the abnormal information.

zYou are allowed to monitor the FIC running state and make the judgment by

observing the LEDs on FIC panels.

1-3

zYou are also provided with the functions of in-service system test, out-of-service

system test. In addition, loopback test and hardware key module self-test are

allowed.

VIII. Regulatory compliance

The AR 46 Series Routers are designed in compliance with the regulations and

standards of China, North America, Europe, Europe, Australia, and Japan in EMC,

safety, network access, and some other aspects.

1.2 Router Model and Structure

The H3C AR 46 series includes AR 46-20, AR 46-40, and AR 46-80. These three

models are similar in chassis structure and layout. All of them use a mid-backplane

allowing front and rear card insertion and can be mounted in 19-inch standard racks.

The following subsections will give you more details about these three models.
