| | Project Overview |
 | | To build a general space Internet architecture that combines differently -challenging parts, our view of the InterPlaNetary Internet is depicted in Figure 1. |
 | | It provides a common infrastructure for communications among the Earth, outer-space planets, moons, satellite, and relay stations placed at gravitationally stable Lagrangian points of planets, etc. It includes the data links (direct link or multi-hop paths) between elements with long-haul capabilities, as shown in Figure 2. |
 | | InterPlaNetary External Network: It consists of spacecrafts flying in groups in deep space between planets, clusters of sensor nodes, and groups of space stations, etc. Some nodes in the InterPlaNetary External Network also have long-haul communication capabilities. |
