7500 a very scalable device by distributing the workload across multiple cards. Each VIP has
its own processor, which is capable of switching IP data packets and providing network
services. In addition to performing packet switching, the VIPs also can provide a set
of distributed IP network services, including access control, QoS, and traffic
accounting (NetFlow).

server to offer a versatile data communications platform that combines in one chassis the
functions of an access server, a router, and analog and digital modems. Companies that need to
centralize processing capabilities for mobile users and telecommuters typically use this device.
The AS5100 is optimized for high-speed modem access and is ideally suited for all traditional
dialup applications, such as access to a host, e-mail, file transfer, and dial-in access to a local-
area network.
