NASA DTN Protocol: How Interplanetary Internet Works

First time accepted submitter GinaSmith888 writes "This is a deep dive in the BP protocol Vint Cerf developed that is the heart of NASA's Delay-Tolerant Networking, better known as DTN. From the article: 'The big difference between BP and IP is that, while IP assumes a more or less smooth pathway for packets going from start to end point, BP allows for disconnections, glitches and other problems you see commonly in deep space, Younes said. Basically, a BP network — the one that will the Interplanetary Internet possible — moves data packets in bursts from node to node, so that it can check when the next node is available or up.'"

    The main problem is the long delay at light speed.

      Were you measuring light speed in American units instead of metric ones?

    The only problem with the BP protocol is the data mining rigs that burst and spread raw SQL queries all over the coast of Amazon.com and then wonder why people are pissed that they can't buy or sell from that site until its cleaned up!
