STS16-20D/STS16-20R to be used as a switch of switches which provides media flexibility in an Token Ring configuration.

The SmartStack STS16-20D/STS16-20R can easily connect with other SmartStack products to deliver a broad range of network carrying capacity. Bandwidth is easily scaled to meet all performance requirements.

Switch of Servers

With client/server applications, many client workstations may attempt to access a single server at the same time. This traffic pattern may create bottlenecks at the server. To further enhance performance, the SmartStack STS16-20D/STS16-20R can deliver dedicated bandwidth to high-speed file servers. All servers perform better with dedicated 16 Mbps bandwidth.

Even better performance can be achieved by installing multiple adapters in the server. By connecting these adapters to the switch, multiple 16 Mbps paths to the server are created, a solution that is only possible when using a switch.

The switch ties together all Token Ring devices lined to a local wiring center. In networks, where a significant portion of the traffic moves locally between client and server, the switch can be very effective.

Switch of Hubs

When network traffic increases beyond the capability of hubs, contention results. Applications suffer and may even fail. The net effect of such a network configuration is that all devices share a single 16 Mbps data path, thus reducing overall network efficiency. The SmartStack STS16-20D/STS16-20R can be very effective when used as a switch of hubs.

The SmartStack STS16-20D/STS16-20R can alleviate contention through microsegmentation, or reducing the number of devices in each shared segment. To provide microsegmentation, the SmartStack STS16-20D/STS16-20R divides a single 16 Mbps segment into multiple 16 Mbps segments. As an example, a workgroup has 16 Mbps of capacity. The 20 ports on the SmartStack STS16-20D/ STS16-20R support 10 simultaneous conversations with 20 hubs, thus providing the workgroup with 160 Mbps bandwidth throughput, which results in a significant gain in bandwidth. Note that on the SmartStack STS16-20D, hubs can only be connected to the network ports 17–20.

Switch of Desktops

The SmartStack STS16-20D/STS16-20R is a cost-effective means of providing dedicated bandwidth to individual desktop workstations. In this application, the SmartStack STS16-20D/STS16-20R replaces a hub, providing excellent, hub-like
