This makes me wonder perhaps TCP is not really suitable or optimized for satellite network.
John Ousterhout (of TCL/TK fame) has recently proposed a new Homa transport protocol as an alternative for TCP in data center [1]. Perhaps a new more suitable transport protocol for satellite or NTN is also needed. That's the beauty of the Internet, the transport protocol is expendable but not network protocol or IP. The fact that IPv6 still a fringe rather than becoming mainstream although it's arguably better than IPv4.
[1] Homa, a transport protocol to replace TCP for low-latency RPC in data centers:

- supriyo-biswas 2y agoThrowing out TCP for a message-oriented layer as Homa does is not really required for addressing this need. Perhaps what would be more useful in this context would be for operating system vendors to perform a HTTP request to a globally distributed endpoint similar to captive portal detection, and then use a more aggressive congestion control algorithm in the case of networks with good throughputs but with high latency.
- teleforce 2y agoI am not saying similar to Homa protocol since it's catering for data center traffic but a new transport protocol alternative to cater for rapid delay variations or jitter needs that's unique to LEO networking.
