A transport protocol's view of Starlink (apnic.net)
Digital communications systems always represent a collection of design tradeoffs. Maximizing one characteristic of a system may impair others, and various communications services may choose to optimize different performance parameters based on the intersection of these design decisions with the physical characteristics of the communications medium.
