Musk Sends Cloudflare CTO's LEO Traffic Proposal to Starlink as 12 Million Users Raise Network Strain

Summary
Musk said he forwarded Cloudflare CTO John Graham-Cumming Knecht’s X proposal to Starlink, putting a new software-based approach to satellite internet traffic control in front of the operator.
LEO networks complicate congestion control because moving satellites, handovers and shifting routes can cause abrupt round-trip-time changes and losses that existing algorithms may mistake for congestion.
A 2026 experimental study on Starlink-like networks found current methods still trade off throughput, delay and retransmissions, suggesting room for protocol changes below the capacity layer.
Starlink’s scale makes that more urgent: SpaceX reported 12 million subscribers at the end of Q2, while Cloudflare said Starlink traffic crossing its network rose 2.3-fold in 2025.
Cloudflare argues tailored TCP and QUIC controls could improve responsiveness and bandwidth use without simply adding more satellite capacity.
