Chapter 1 Router Overview

1.1 Introduction

3Com 6000 Routers are next generation high-performance edge routers that 3Com Corporation solely developed. They provide high forwarding performance and a broad service range. The Router 6000 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 Router 6000 provides complete network solutions for service providers and enterprises.

The following are the major features of the Router 6000.

I. Abundant FIC options

Abundant FICs are available with the Router 6000 allowing great flexibility and investment protection.

II. Ethernet access

The electrical and fiber (multi-mode and single-mode) FE FICs available with the Router 6000 support PPPoE and PPPoEoA that can offer authentication, authorization, and accounting (AAA) services for Ethernet access, hence satisfying the requirements of government offices and enterprises in broadband access.

III. ATM and DSL

Digital subscriber line (DSL) is a simple but highly efficient broadband technology that 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 Router 6000 can connect the medium-to-small-sized enterprises to the digital subscriber line access multiplexer (DSLAM) equipment through a public switched telephone network (PSTN) and then to the Internet.

Asynchronous transfer mode (ATM) transmits, multiplexes, and switches information in cells. The Router 6000 can be installed with these ATM cards: 25 Mbps, 155 Mbps, E3, and T3. The cards support ATM adaption 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 medium-and-small-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 each routers
