New Research Related to SCPS
While the SCPS protocol suite enables terrestrial networks to extend into cislunar space, extending the internet to reach other planets requires new techniques. In 1998, DARPA funded the JPL/MITRE/SPARTA SCPS team to explore how an Interplanetary Internet might be designed. Dr. Vint Cerf joined the team, and a number of new concepts were explored.
The primary challenge was in dealing with light-time delays to other planets - minutes or even hours could elapse between a signal and its acknowledgement. It soon became evident that if one could deal with minutes or hours of delay caused by interplanetary distances, the same techniques could be equally useful for dealing with delays caused by disconnection or other comm link disruption.
In recent years, this work has been generalized and brought into the Internet Research Task Force as a Working Group on Delay (or Disruption) Tolerant Networking. For further information see: http://www.dtnrg.org
