The Space Router provided the ability to route Internet Protocol computer network traffic on board the satellite, which enabled users of Web, VoIP, and other IP applications to directly communicate without having to double-hop data to and from an intermediate Earth station. The ability to avoid the double-hop to the Earth station can reduce latency, which is approximately 250 ms for GEO satellites. Latency reduction is a key driver for increased use of real-time applications, including video teleconferencing, over satellites.[citation needed]
The avoidance of the double-hop to the Earth station can also reduce satellite transponder costs. Routing IP traffic natively on the satellite with the router's built-in Cisco IOS Software and onboard software-defined radio can increase throughput, reduce latency, and enable flexible bandwidth-on-demand real-time applications between users in different geographic regions that do not have easy access to fiber networks.[citation needed]
IRIS is an example of a hosted payload, a method to add multiple non-core components to satellite to reduce the cost of launching the components into orbit.[3]
