Up to now, communications have been done on a layer-2<br> point to point basis, with sometimes the use of relays, therefore no<br> layer-3 networking was possible. RFC4838 reports an assessment done<br> around 25 years ago concluding that the IP protocol stack was not<br> suitable for deep space networking. This result lead to the<br> definition of a new protocol stack based on a store-and-forward<br> paradigm implemented in the Bundle Protocol(BP). More recently,<br> space agencies are planning to deploy IP networks on celestial<br> bodies, such as Moon or Mars, ground, and vicinity. This document<br> revisits the initial assessment of rejecting IP and provides solution<br> paths to use the IP protocol stack, from IP forwarding to transport<br> to applications to network management, in deep space communications.<br><br><br><br>The IETF Secretariat<br><br><br></div></div></blockquote></div><br></div></body></html>
