Chapter 1 Introduction
1.1 Quidway R2600/3600 Series Modular Routers
Quidway R2600/3600 series modular routers (referred to as R2600/3600 series
hereafter) are independently developed by Huawei for enterprise networks. They can
be used as core routers in medium- and small-sized Intranets, or as access servers at
some major branch offices.
With a modular structure, R2600/3600 series adopt the Versatile Routing Platform
(VRP), a proprietary software platform of Huawei, and incorporate high-performance
processor, bus technology and fast routing policy. While providing a large array of
service interfaces, it can also be used together with Quidway
R1600 series, Quidway
R2500 series, and Quidway NetEngine08/16E series routers to provide overall
solutions for large- and medium-sized industry users such as telecom, private network
carrier, ISP, finance, tax, police, and railway, etc. At the same time, its function modules
comply with various network standards. So R2600/3600 series are in the best interests
to protect your existing investments while guaranteeing interoperability at various
levels with major products on the global market.
1.2 Models
R2600/3600 series include: R2620,
R2621, R2630, R2631, R3640, R3680, R2630E,
R2631E, R3640E and R3680E:
z
R2620 and R2621 adopt Power PC 8240 CPU main board, but they differ from
other R2600/3600 series routers in that they have two fixed synchronous serial
interfaces besides the fixed Ethernet interfaces.
z
R2630E, R2631E, R3640E and R3680E differ from R2630, R2631, R3640 and
R3680 in that the former adopt Power PC 8240 CPU main board and the latter
adopt Pentium CPU main board. They have the same software features and
functional implementations. The interface modules used by them are completely
compatible, but the former are more powerful in their processing capability and
packet forwarding performance.
R2600/3600 series provide different number of module slots:
z
Quidway R2620 provides one 10/100Mbps Ethernet interfaces, two synchronous
serial interfaces, and two standard PCI slots.
z
Quidway
R2621
provides two 10/100Mbps Ethernet interface, two synchronous
serial interfaces and two standard PCI slots.
z
