In a Q&A, he talks about one of his favorite aha moments, way back in 1977. "We did a demonstration where we were simulating someone in a mobile battlefield environment going across a continental network, then across an intercontinental satellite network, and then back into a wireline network to a major computing resource in national headquarters. Packets were traveling 94,000 miles round trip, as opposed to what would have been an 800-mile round trip directly on the ARPANET. We didn't lose one bit! After that exciting demonstration, we worked very hard on finalizing the protocols.""
