Chapter 1 Overview
1.1 Brief Introduction
Quidway AR 28 Series Routers were independently developed by Huawei
Technologies for use on enterprise-level networks. Depending on the network size,
Quidway AR 28 Series Routers can be either core routers on small and medium
enterprise networks, or access routers for network branches on some large-sized
enterprise networks. Therefore, Quidway AR 28 Series Routers are suitable for the
application on the carrier-level networks, such as telecom management networks and
billing networks.
Quidway AR 28 Series Routers adopt modular design and provide a wide range of
optional MIMs (Multifunctional Interface Modules) and SICs (Smart Interface Cards).
Among all models of the series, the AR 28-10, the AR 28-11, the AR 28-12, the AR
28-13, and the AR 28-14 are available with two types of units: AC-powered and
DC-powered.
Quidway AR 28 Series Routers adopt high speed PowerPC microprocessor and the
VRP (Versatile Routing Platform), a network operation system platform developed by
Huawei Technologies. Besides the benefit of simple configuration, VRP provides rich
network security features, and supports dumb terminal access, SNA (Systems Network
Architecture)/DLSw (Data-Link Switching), IP multicast, and abundant QoS (Quality of
Service) features. Thereby, Quidway AR 28 Series Routers can operate together with
other Quidway series routers and Ethernet switches to provide overall end-to-end
network solutions for clients in industries such as telecommunication, ISP, finance,
taxation, public security, and transportation, medium-and-large-sized enterprises.
Quidway AR 28 Series Routers deliver features of xDSL (Digital Subscriber Line),
MPLS (Multiprotocol Label Switch), NTP (Network Time Protocol). Networked with the
NE Series High-End Routers, the AR 28 series can provide comprehensive solutions
for carriers and large industrial users.
Currently, the AR 28 series include these models:
z AR 28-09
z AR 28-10/28-11/28-12/28-13/28-14
