Delay/Disruption Tolerant Networking (DTN) provides solutions to space communication challenges such as disconnections when orbiters lose line-of-sight with landers, long propagation delays over interplanetary links, and other operational constraints. DTN is critical to enabling the future space internetworking envisioned by NASA. Interoperability with international partners is essential and standardization is progressing through both the CCSDS and the IETF. The DTN architecture, defined in RFC 4838, "Uses a flexible naming scheme (based on Uniform Resource Identifiers [RFC3986]) capable of encapsulating different naming and addressing schemes in the same overall naming syntax."
