Modern and prospective spacecraft data system networks consist of many systems and sensors producing streaming traffic. Outside spacecraft video cameras also generate intensive data streams. Motion video traffic requires specific latency and speed. Video frames should be delivered with small delays and jitter over high-rate SpaceFibre networks. The paper considers live streaming video over onboard spacecraft networks with its fixed packet size and periodical issue, detection of packet reordering, small delays. ARINC-818-2 and CCSDS Digital Motion Imagery streaming traffic, characteristic of video streams are analysed, requirements for streaming services and transport protocol are presented, the overview of existing streaming protocols is done. The STP-2 protocol was proposed for streaming data service in SpaceFibre networks. It is based on STP, which provides a number of native streaming features. STP-2 has some significant modifications that improve delivery of streaming data flows over high-rate SpaceFibre networks. Use cases for it application illustrate its benefits.
