Grizzly Intelligent Edge Device Overview

Enterprise customers with remote geographically separated sites are utilizing satellite networks to access the Internet and provide access to the corporate backbone. Inherent to the spread of these networks is the search for small access devices that allow the connection to the Internet in a very user friendly way but with a growing number of offered services, comprising basic IP functionalities (e.g., DNS, DHCP,NAT), performance enhancements (e.g., PEP and Compression) and security and traffic control services.

Traditionally a subset of these services are available as part of an edge router or can be achieved through the combination of a number of devices (e.g., VPN server, QoS manager, router). However, these products are not optimized for operation over a satellite link and
often conflict with each other. For example a VPN access device encrypts traffic so
performance enhancement features like compression cant be utilized.
