Space Internetworking Services Area Overview 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
