Part of an industry-government 3-year program to demonstrate the use of an internet router in space: Internet Routing In Space (IRIS).

Cisco will provide commercial IP networking software for the on-board router and SEAKR Engineering Inc. will manufacture the space-hardened router and integrate it into the IRIS payload. Concerto Advisors, a financial advisory firm based in Iowa City, IA, is organising equity financing for a new company to provide the funds to design, build and operate the equipment used for the demonstration.

IRIS will serve as a computer processor in the sky, merging communications being received on various frequency bands and transmitting them to multiple users based on data instructions embedded in the uplink. The IRIS payload will interconnect one C-band and two Ku-band coverage areas. The IRIS architecture and design allow for flexible IP packet (layer 3) routing or multicast distribution that can be reconfigured on demand. With the on-board processor routing the up and down communications links, the IRIS payload is expected to enhance satellite performance and reduce signal degradation from atmospheric conditions.

Cisco later announced that its router is functionning properly and provided 99.95% availability during tests.
