[Starlink] Main hurdles against the Integration of Satellites and Terrestial Networks

[David Fernández]

The use of MPTCP on satellite links has been analyzed here (for
example) and the use of PEPs in GEO satellite links prevent the use of
MPTCP:
https://datatracker.ietf.org/meeting/106/materials/slides-106-mptcp-mptcp-satellite-01#page=13&zoom=auto,-91,32

Another option could be MPQUIC (still in development AFAIK),

I have been told in the past that a tighter integration of satellite
and terrestrial networks is required mainly for business purposes
(billing).

David
