DTN Marshall Enterprise(MFS-33978-1)

DTN Marshall Enterprise is a fully compliant CCSDS Delay/Disruption Tolerant Network (DTN) router that has been used to conduct International Space Station (ISS) payload operations for many years. Communications in space are characterized by their disrupted, wireless nature. Whether due to occultation, scheduling, cost or solar flares, spacecraft must handle interruptions in connectivity and data losses. Delay/Disruption Tolerant Networking (DTN) using the bundle protocol (BP) can maximize the efficient use of links to and among spacecraft. As part of NASAs efforts to deploy DTN in space, the HOSC developed a general purpose DTN router based on the SourceForge DTN2 version 6 reference code and reinvented a previously develop capability called the External Router. This allows non-network cognizant operators to manage the ground gateway as though it were another piece of the ground system without perturbing its actual specifications. The HOSC has deployed their implementation of the DTN Bundle Protocol (BP) to payloads on the International Space Station (ISS).The current request is to export and make available for technology transfer the current DTNME implementation. It is also desirable for it to reside on github.com/NASA/DTNME. DTNME implemented DTN protocols as primarily defined by RFC 5050 and several other RFCs. This was also used by the HOSC to verify a new CCSDS standard (Bundle Protocol Specification CCSDS 734.2-B-1) that is used in various programs. The standard or the next generation is now being targeted for Gateway. After successfully using it operationally, we have accumulated a new patch set. The combined implementation is what we would like to release as DTNME v0.1. DTN2 software updates were originally released to SourceForge.net under NTR# 1428003694. This was a patch update that incorporated functionality of the CCSDS standard and pre-operational generic features used on the ISS.
