Unique System Features

UNIQUE SYSTEM FEATURES

The CyberSWITCH combines unique features that improve cost-effectiveness, reliability, and performance for wide area network connections to remote devices. These features include:

•Bandwidth Agility

The CyberSWITCH dynamically controls the bandwidth in use between itself and other PPP devices. This is accomplished by establishing and disconnecting calls. The number of calls is limited only by the types and number of lines available. The system monitors the connections for utilization and will add and remove the connections based on user-configurable throughput parameters. As network bandwidth requirements increase or decrease, the system will automatically adjust the number of network connections. Thus, your network costs will reflect the actual bandwidth being used.

•Filtering

The CyberSWITCH’s filtering feature allows you to control the flow of frames through the network. Filtering becomes necessary if you need to restrict remote access or control widespread transmission of sporadic messages. Customer-defined filters can forward messages based on addresses, protocol, or packet data.

•Combining Leased Line and Switched Connections

Use the Switched Connections feature to automatically backup failed or overloaded leased lines (for example, in peak hour overflow situations). The capability of combining switched connections with leased line capacity allows you to reduce costs and greatly improve the reliability and performance of leased line networks.

The following graph illustrates the relationship between cost and hours of usage when comparing a switched connection to a dedicated connection:

•Data Compression

The CyberSWITCH can negotiate compression algorithms with another device on the network. After successfully negotiating compression, data is compressed by the remote device and transmitted to the CyberSWITCH system. The system decompresses the data, processes the information contained in the user data, and forwards the data as required. The system can receive data coming over a WAN or a LAN, and compress the data before transmitting it to another device on the network. The net effect is to increase interconnect bandwidth by decreasing transmission time. If negotiation for compression fails, data is transmitted uncompressed.
