Glenn Research Center Networks & Architectures Branch Communications Technology DNCO Conference: 03 Dec The Cisco router in low Earth orbit (CLEO) Put a COTS Cisco router in space Determine if the router could withstand the effects of launch and radiation in a low Earth orbit and still operate in the way that its terrestrial counterparts did. Ensure that the router was routing properly Implement mobile network and demonstrate its usefulness for space-based applications. –Since the UK–DMC is an operational system, a major constraint placed on the network design was that any network changes could not impact the current operational network

Glenn Research Center Networks & Architectures Branch Communications Technology DNCO Conference: 03 Dec Summary - Timeline of Events NASA’s first opportunity to touch CLEO was May 11th, 2004 At best, satellite passes were: – 1 per day, 3 days per week, 8 minutes per pass –Cisco router testing next week (from actual ): Tues 11/05/2004: 10h05UTC pass (6:05 EDT) Wed 12/05/2004: 10h43UTC pass (6:43 EDT) Fri 14/05/2004: 10h20UTC pass (6:20 EDT) Successful VMOC metrics testing was performed June It is highly doubtful this would have been possible without the use of IP!

Glenn Research Center Networks & Architectures Branch Communications Technology DNCO Conference: 03 Dec CLEO/VMOC Lessons Learned The ability to have all the tools available in a full IOS on the onboard router proved invaluable –Argument for slimmed-down IOS May be more robust or easier to qualify rigorously for the space environment. –Argument for full IOS Removing functionality may result in less stable code rather than more stable code, as any change in software can affect the robustness of software and second. –Full IOS has been tested daily by hundreds of thousands of users It is quite probable the functionality taken out will end up being the functionality one needs for some later, unforeseen configuration need. Mobile networking greatly simplifies network configurations at the ground stations and adds an extremely insignificant amount of overhead (three small packets per session for binding setup). –Triangular routing is preferred if the rate on the terrestrial links cannot meet or exceed the rate of the downlink. –Triangular routing along with new file transfer applications enables full utilization of the downlink.

Glenn Research Center Networks & Architectures Branch Communications Technology DNCO Conference: 03 Dec CLEO/VMOC Lessons Learned The interface between asset owners will have to be identified and some special software written when sharing infrastructure –Use of commercial standards (IP, Simple Object Access Protocol, XML) make implementing these software interfaces much quicker and easier than if noncommercial standard protocols were used. The engineering model of the onboard and ground assets is a necessity According to Universal Space Networks and Integral System Integration, there are products available for ground station TT&C that have become de facto industry standards. Using them will greatly simplify ground station integration and reduce costs. –An example provided by USN and ISI: IN–SNEC’s CORTEX satellite telemetry products for ground stations

Glenn Research Center Networks & Architectures Branch Communications Technology DNCO Conference: 03 Dec NCO Experiences Successful NCO has more to do with building trust relationships at the “people level” than it has to do with technology. Putting NCO in an operational system is the true test. –This forces ALL security issues to be address! Internetwork Centric Operations, NCO across various networks owned and operated by various entities if far different the NCO within your own network. –Everybody has to expose themselves to some degree. That degree has to be negotiated up front. I need to understand how your system works and you need to understand how my system works. Strengths and vulnerabilities are exposed to some degree. –Internetworking NCO is like a marriage 50/50 is doomed to failure. 100% commitment is required by all parties. –You MUST understand and accept the needs of the other parties. –Patience and Persistence, Patience and Persistence, and more Patience and Persistence!

Glenn Research Center Networks & Architectures Branch Communications Technology DNCO Conference: 03 Dec International Interoperability NASA claims of International Interoperability –For the most part it is at the data-link layer and modulation and coding (CCSDS) –Federal Express layer. –The space-link extension (SLE) Not required for IP-based systems (at least the data-link extension portion of the SLE protocol) Wraps data-link in IP; therefore all security issues associated with tying IP networks together must be addressed Mission Planning and Scheduling service must be implemented. –A “framework” for such exists as part of the mission services portion of SLE Full interoperability means –Forward and return data is actually transmitted though systems owned and operated by various entities. (Note, this has an enormous security aspect to it.) Ground stations Network-layer space relays (satellite, rovers, or whatever infrastructure may be utilized as part of the communication network). –Requires autonomous routing mechanisms –Store and forward such as Delay/Disruption Tolerant Networking (DTN) Requires securing data at rest
