  1. Space Internetworking Services Overview Robert C. Durst Director, Space Internetworking Services Area Consultative Committee for Space Data Systems durst@mitre.org +1 703 983-7535

  2. Space Internetworking Services Overview • Space Internetworking • The SIS charter and portfolio • Current SIS program of work

  3. Spacecraft Onboard Interface Services Space Internetworking Services Mission Operations and Information Management Services Space Link Services Systems Engineering Cross Support Services CCSDS Engineering Steering Group Technical Areas

  4. Conventional Internetworking • Richly connected • Continuous availability • Error free • Negligible delay • Symmetric channels • High data rates

  5. Space Internetworking • Intermittently connected • Service disruption • Error prone • Significant-to-huge delay • Asymmetric or unidirectional channels • Constrained data rates

  6. Space Internetworking Services AreaOverview • Scope – end-to-end communications • Between spacecraft and ground • Among spacecraft • Within a heterogeneous spacecraft • Network through Application layers • Independent of (and potentially spanning multiple) subnetwork technologies • Independent of application data semantics
