Cisco announces that it has successfully tested a radiation-tolerant router aboard a commercial satellite, the first step in creating IP networking technology that can run in space. The test, part of the Defense Department's Internet Routing in Space program, can lead to less latency and better efficiency in moving voice, video and data traffic, according to Cisco. The military will test it now for the next three months, followed by commercial tests by Cisco.

The next step is to see if the technology can work well enough for military
and commercial uses.
Cisco announced Jan. 18 that the Department of Defense's IRIS (Internet
Routing in Space) technology program successfully tested the radiation-tolerant
router and the Cisco IOS Software's networking capability that was launched Nov. 23, 2009, on a
satellite built by Intelsat General.
The goal of the program is to enable the routing of voice, video and data
traffic from one satellite to the next using common Internet Protocol, without
having to move between relay satellites or to stations on Earth. The in-space
router would be able to send data to multiple ground receivers in a single
step, reducing latency and increasing transponder utilization by eliminating
multiple hops between the satellites and Earth.
It also will improve communications capabilities for users.
"This milestone is another step in our strategy to expand borderless
networks into space and redefine how satellite communications are delivered,"
Steven Boutelle, vice president of Cisco's Global Government Solutions Group,
said in a statement. "This technology can help transform satellite
communications around the world by reducing latency and increasing the
The IRIS program is a DOD Joint Capability Technology Demonstration that is
managed by Cisco and Intelsat. The Defense Department will test the technology
for military use over a three-month period ending in April. After that, Cisco
will test it for commercial uses for a year.
