Internet Pioneer Wants to Take Net Off Planet

Vint Cerf takes his title of Chief Internet Evangelist for Google seriously. He is knee-deep in several projects to bring the next versions of the Internet into the world -- or in some cases, beyond the world and into the solar system. One of his pet projects includes an extraterrestrial Internet that uses a protocol other than IP.

Cerf sat down with Network World's Cisco Subnet editor, Julie Bort, at the annual Digital Broadband Migration conference in Boulder, Colo., to discuss the InterPlanetary Internet, cloud computing standards, the Semantic Web and other topics.

About a year ago, you began talking a lot about a concept called the "InterPlanetary Internet" stretching the Internet so that it can reach into outer space. What can you share about that project?

It's happening. It's not using the Internet Protocol. It's using the new Bundle Protocol that was developed as part of the more general notion of delay-and-disruption-tolerant network.

We recognized as far back as 1998 that the traditional Internet design had implicit in it the assumption that there was good connectivity, and relatively low latency, whereas in a space environment, when you are talking at interplanetary distances, you have speed-of-light delays and those can be minutes to days. We need this new Bundle Protocol to overcome the latencies and all the disconnects that occur in space, from celestial motion [and from] orbiting satellites.
