How It Works

Because DSR leverages industry standard LAN equipment, complex wired configurations are no longer necessary. All of the analog KVM signals are converted in real time to digital form and transported using standard Ethernet protocols. This data is then fed into compression engines, which compare the information already transmitted to the operator with the new information presented from the server. Once those changes are analyzed, they are sent to a high-powered processor, which packs the information and transmits it via the Internet to the operator. This user can now view the computer video through a PC-based application program called DSView.

DSView

DSView shows the user a list of computers that he has permission to connect to. Once the user has chosen one of the computers, a connection is established between DSView and the appropriate port on a DSR. Video data is then sent from the DSR to DSView. The remote computer screen image is then scaled to fit appropriately into the window on the PC desktop that is running DSView. This allows multiple computers to be viewed simultaneously, each displayed in its own window. These windows can be arranged on the desktop in any manner desired.

LAN

Users can decide if they wish to connect the DSR to their existing LAN, or create a separate out-of-band LAN just for maintenance of their servers. Burst loads of approximately 20 to 30 Mbits per second are reached during full high-resolution screen refreshes.

Transmission

Typical installations may expect ten to twenty operators to be simultaneously viewing and controlling servers on a single 100Mbit collision domain. In most cases, they will see near real-time performance on any connection.
