UDcast UDgateway VPN - Enhanced VPN Appliance


The UDgateway VPN is the first all-in-one appliance specifically adapted for a broadband satellite-based VPN - Virtual Private Network. All key IP features such as routing and QoS, security and tunneling, compression and caching are embedded in the appliance along with performance enhancement technology. UDcast's best-of-breed core technology provides an enhanced end-user experience, based on two-way TCP acceleration, QoS-based traffic differentiation, HTTP pre-fetching, as well as web and DNS caching.

The VPN can be created over a satellite only infrastructure or over a mix of two-way satellite with terrestrial backhaul. The satellite and/or terrestrial site connections can be based on any IP access service such as basic Internet access. Site to site communication is kept private throughout using strong IP traffic encryption. UDcast Udgateway VPN's unique technology enhances upload and download performances, by compressing and accelerating TCP-based applications both ways, end-to-end.

The UDgateway VPN appliance functions with any two-way satellite system. When located on a satellite-based access, it sits between the indoor unit and the local area network, and handles all VPN access traffic coming from the corporate site. When located on a terrestrial based central site, the UDgateway VPN is integrated in any location near the Internet access, generally in a DMZ - De-Militarised Zone. Designed to be easily installed, configuration is done via a web-based interface. A wizard automates the setup process, requiring the input of just a few parameters.

UDcast UDstation Access - Broadband Access Server - UDgateway Product Companion

UDcast UDstation Access - Broadband Access Server - UDgateway Product Companion

UDcast UDstation Access Description:

The UDstation-Access is a central appliance located at the satellite hub. It is the key product companion for the UDgateways located at the end-customer sites delivering enhanced broadband Internet access over two-way satellite systems. This appliance is shared by all the connected UDgateways and provides the necessary server side/hub elements for full functionality.

Thanks to the UDstation-Access appliance, in conjunction with the UDgateway appliances, service providers can provide premium type services with key benefits for both the service provider and the end-customers. Amongst these are strong network security, on the fly IP traffic compression and valuable performance enhancement. The UDstation-Access implements global performance enhancement through TCP acceleration and data compression, central security control and enforcement through site authentication and key distribution, as well as essential installed base administration tools such as the ability to carry out remote software upgrades.

The UDstation-Access appliance is highly flexible ensuring easy integration with the service provider's hub and fully adapting to specific needs and constraints. The appliance can also be located close to the hub, for example in a public IP zone, in order to reduce the risk of impacting the existing satellite system. Through the use of the UDstation-Access the service provider can choose which end-customer sites benefit from a premium service enabled by UDgateways, and which do not, thus delivering two classes of service from a same hub.

Based on a powerful hardware platform, the UDstation-Access appliance is designed for the satellite service provider. Each appliance can support up to a full satellite transponder capacity.
