Frame Relay Card

The Frame Relay interface is based on Frame Relay Forum (FRF) standards and recommendations, thus simplifying installation/ configuration issues and providing a seamless satellite-based extension to corporate and public telecommunications networks. The FR functionality is supported on an interface card that is added to any of the terminals in the VSATPlus II product line and will interface to standard routers, FRADs and data switches. Full configuration and control of the Frame Relay capabilities are provided by the StreamView NMS which can be connected to any terminal in the network.

QoS (Quality of Service) and Congestion Management are key attributes of Frame Relay that are supported by the VSATPlus II Frame Relay feature thus allowing real-time applications (such as Voice and videoconferencing) to be combined with less time-sensitive data applications. PolarSat’s Frame Relay interface is a unified platform that supports multiple service applications required by today’s communications networks such as IP traffic, LAN-LAN interconnectivity, database/Internet access, PSDN/PSTN interconnections, videoteleconferencing, datacasting, and voice/FAX applications.

Virtual private networks (VPNs) are created through the use of distinct DLCI assignments for different customers. User traffic is routed over each DLCI to any destination within the network. A DLCI can be a point-to-point or point-to-multipoint connection and user traffic can be balanced or asymmetric.

Satellite bandwidth is allocated through CIR, EIR, and QoS definitions and optimized using dynamic bandwidth allocation (BoD) techniques, thereby minimizing the recurring cost of operating a communications network. This approach provides user circuits with guaranteed bandwidth and the ability to request more from the network.
