Intranets

Intranets are the next wave in enterprise networking as they

enable a wide spectrum of applications, which present a whole

new value proposition in terms of streamlining fundamental

business processes throughout the enterprise. The convergence of

voice, video, and data is also being witnessed in the Internet and

intranets with the emergence of voice over IP and ATM and

through multimedia applications such as video multicasting and

conferencing.

Intranet applications create trafﬁc patterns that are dynamic

and varied in their requirements from the network. The

underlying network infrastructure, therefore, needs to provide

scalable and advanced network services such as IP multicasting

and IP and ATM QoS.

Cisco’s Value

Cisco’s experience in building some of the largest enterprise

networks while also building the largest network of them all—the

Internet—has been integrated into Cisco IOS software over many

years. Cisco IOS software is the common framework integrated

across all Cisco products; it provides the foundation for building

a scalable and intelligent network infrastructure.

Cisco 7500/7200 series routers and the Cisco 12000 GSR

series power over 85 percent of the Internet and provide the

scalable infrastructure needed to support the Internet.

Incorporating the capabilities of the Cisco 7500 and 12000 series,

the Catalyst 8500 series is specialized for campus backbone

applications.

The Catalyst 8500 integrates smoothly into any

existing network; it is a powerful new addition to the Cisco

end-to-end solution, consisting of industry-leading products such

as:

• Catalyst 5000/5500 series, ideal for the wiring closet and LAN

backbone aggregation

• Cisco 7500/7200 series routers for diverse LAN and WAN

integration, multiprotocol routing, and System Network

Architecture (SNA) integration

• Cisco LightStream 1010 and Cisco IGX 8400 wide-area

switches for LAN/Metropolitan-area network (MAN)/WAN

Asynchronous Transfer Mode (ATM) and Frame Relay
