SIS_DTN 3 Generic File Transfer BoF Generic File Transfer BoF (in the library) I’d like to try to politely dissuade them from using ‘file transfer’ as part of a multi-hop (end-to-end) data delivery mechanism. May 2010

SIS_DTN 7 Forward Work: Security Need: Multiple agencies on ISS all flowing data through one shared infrastructure Need for interoperability Certainly both ends need to agree on how to secure data; needed if you ever WANT to send data between agencies securely There is currently an Internet Research Task Force RFC for bundle security ( It conflates routing and security It imposes ciphersuite requirements that quickly become out-of-date It allows for complex (Byzantine) nesting / overlapping security that makes implementation extremely difficult Internet Research Task Force is currently working a ‘Streamlined Bundle Security Protocol’ (SBSP) Decouples routing from security Strongly separates ciphersuites Support NASA can work the document and interface with IRTF dtnrg NASA can probably get two implementations (ION, DTN2) via some combination of NASA, other US participants NEED: second agency support (at least monitor the book) NEED: semi-formal collaboration with SEA-Security WG October 2013

SIS_DTN 8 Security Discussion Is this high priority for the WG? (i.e. is there something else we should do first?) Who could contribute to CCSDS DTN Security protocol recommendation? October 2013

SIS_DTN 9 Forward Work: Network Management Need: Network monitor and control Need for interoperability: Visibility / transparency for cross-agency network data transfer (what are YOU doing with MY data) Probably NOT cross-agency control Support NASA can work the document (and interface with IRTF dtnrg if necessary) Can probably get two implementations (ION, DTN2) via some combination of NASA, other US participants NEED: Second agency support (at least monitor the book) NEED: Use cases / scenarios / requirements October 2013

SIS_DTN 10 Network Management Discussion Is this high priority for the WG? (i.e. is there something else we should do first?) Who could contribute to CCSDS DTN Network Management protocol recommendation? October 2013

SIS_DTN 11 Forward Work: Routing Need: BP provides a possibly multi-hop end-to-end service, need routing Need for interoperability: Need consistent set of rules for routing / forwarding bundles so that they don’t go in circles Support NEED: Someone to be book captain NEED: Second agency support (at least monitor the book) NEED: Use cases / scenarios / requirements October 2013

SIS_DTN 12 Routing Discussion Is this high priority for the WG? (i.e. is there something else we should do first?) Who could support? October 2013

SIS_DTN 13 Forward Work: Erasure Coding for LTP Need Improve LTP performance Need for interoperability: Would significantly change the bits on the wire for LTP Support DLR has an implementation (that Tomaso will talk about tomorrow AM) Not clear if NASA has support here Propose to continue discussion on Wednesday after Tomoso’s presentation October 2013
