SmartStack STS16-20D/STS16-20R Token Ring Switches Installation and User Guide
Introduction
network management statistics. Total network capacity and throughput increase 
dramatically for attached desktop workstations.
Switch of Floors and Buildings
For network managers, multistorey buildings and campuses can represent a unique 
networking challenge. How can a network manager provide an efficient LAN 
interconnect for users that are located on several floors of a building or in different 
buildings?
Token Ring switching and the SmartStack product family can provide the best 
solution. The SmartStack STS16-20D/STS16-20R provides enhanced throughput 
to local wiring closets that can be connected to a switch located in the data center.
Many networks consist of users located in different buildings of a campus 
environment. The switches can be used as a collapsed backbone interconnecting 
multiple buildings of a campus. They can provide the connectivity solution and 
enhanced throughput that such campus environments require.
Switch of Routers
Router technology has had a significant impact on the design of today’s 
internetworks. Routers have become the cornerstone of most production networks. 
Although well equipped to provide firewall, WAN connectivity, security, and 
connection between dissimilar LANs, routers are unable to provide high throughput 
between desktop devices and servers. Because of these limitations, routers and 
switches perform complimentary functions in the network.
The SmartStack STS16-20D/STS16-20R can be used as a front-end to routers to 
increase performance in each subnet. Communication between local clients and 
servers is enhanced at the workgroup level below the router.
The SmartStack STS16-20D/STS16-20R can also be used to back-end routers. In 
networks were many routers are interconnected over Token Ring and backbone 
performance is not acceptable, the SmartStack STS16-20D/STS16-20R provides 
nonblocking communication between the routers for enhanced network 
performance. This provides protocol transparency with enhanced throughput in 
each subnet between local servers and desktops, thus allowing network managers 
to build logical networks as large as network layer protocol and broadcast traffic 
allow.
The Switched Port Analyzer also gives a collapsed backbone network superior 
network management and the ability to perform protocol analysis from a single 
location. The Switch Port Analyzer provides the latest technology for monitoring 
switch-based networks and helps to reduce the cost of managing these networks.
