Comtech Vipersat Satellite Communications Management System

Vipersat Network Management

The Comtech EF Data Vipersat Management System builds on years of providing our customers with the most advanced automated bandwidth and capacity management system in the industry. VMS is a feature-rich, comprehensive, intuitive operator’s network configuration, management, and control tool. It is designed to enable network administrators and satellite service providers to easily configure networks and rapidly and effectively respond to network anomalies. More than a network monitor and control platform, VMS automates the carrier switching and spectrum management processes within the satellite network. These capabilities allow SCPC carriers to be switched automatically based on application, load, or schedule, providing ondemand services and unparalleled space segment savings.

Dynamic Single Channel per Carrier (dSCPC)

Traditional Single Channel per Carrier satellite communication links do not change. As link budgets and network throughput requirements are based on the worst case scenario, these links are often underutilized.

With increasing satellite bandwidth costs combined with increasing throughput requirements, you are looking for the most efficient
utilization of your operating budget. Dynamic Single Channel per Carrier provides increased efficiency in bandwidth utilization, carrier management, as well as personnel required to manage the network.

Altering a link typically requires substantial resources on both sides of the link. An analysis must be done to determine what new data rate the modem will require to be optimized for the network traffic load. A new link budget must be performed, including power calculations. A new frequency plan must be created, often requiring changes to multiple sites to accommodate the change. Finally, personnel must be located at both sides of every link involved simultaneously in order to reduce outage time. Leveraging dSCPC enables automation of the above.

When a node in the satellite network detects a change in the amount of throughput required via several automatic detection algorithms, it will automatically request that change from the VMS. The VMS will look at all satellite resource allocations and automatically determine a new frequency plan, power level, data rate, FEC, and modulation schemes for all modulators and demodulators involved in the change.

All associated devices will simultaneously be sent these parameters over the air without human intervention. These calculations are done in fractions of a second with the entire process taking less than one second of total data loss in most cases.

dSCPC yields true bandwidth-on-demand, providing low-latency, low-jitter dedicated SCPC connections when needed for real-time
applications, such as Voice over IP (VoIP), video conference, broadcasts and large applications (file or image transfers).
At any time, the operator has full manual override ability, and can turn on/off the auto-detection mechanisms.
