Scalability
The Cisco IOS software uses scalable routing protocols to avoid need-
less congestion, overcome inherent protocol limitations, and bypass
many of the obstacles that result from the complex scope and geo-
graphical dispersion of an internetwork.
The Cisco IOS software eliminates the need for static routes and re-
duces network costs by efficiently using network bandwidth and re-
sources. Advanced features such as route filtering, protocol
termination and translation, smart broadcasts, and helper address ser-
vices combine to create a flexible, scalable infrastructure that can keep
pace with evolving network requirements.
Reliable, Adaptive Routing
The AI2524 Cisco IOS software identifies the best network paths and
routes traffic around network failures. Policy-based features such as
route filtering and route redistribution save network resources by pre-
venting data from being broadcast to nodes that do not need it. Priority
output queuing and custom queuing grant priority to important ses-
sions when network bandwidth is scarce. Load balancing uses every
available path across the internetwork to preserve bandwidth and im-
prove network performance. The Cisco IOS software also provides the
most effective and efficient scaling available for network applications
that require transparent or source-route bridging algorithms.
Remote Access and Protocol Translation
Your router connects terminals, modems, microcomputers, and net-
works over serial lines to LANs or Wide-Area Networks (WANs). It
