Well, I have some concerns about how you implement an anycast address
in a transparent satellite.
If the pre-requisite for this is that the satellite is a router, I
don't see this happening anytime soon. I am not aware of any system,
not deployed, even designed with satellites being routers, but IRIS2
could be the first, maybe:
https://defence-industry-space.ec.europa.eu/eu-space-policy/eu-space-programme/iriss_en
Bufferbloat will be checked and prevented as much as possible in IRIS2.
Regards,
David
