A transport protocol's view of Starlink
’s View of Starlink May 2024 Digital communications systems always represent a collection of design trade-offs. Maximising one characteristic of a system may impair others, and various communications services may chose to optimise different performance parameters based on the intersection these design decisions with the physical characteristics of the communications medium.
If you are high enough to clear various mountains that may be in the way, there is, however, a critical velocity where the projectile will be captured by the earth’s gravity and neither fall to ground nor head out into space (Figure 1). The Bottleneck Bandwidth and Round-trip propagation time (BBR) protocol [11] is a TCP congestion control algorithm developed at Google a decade or so ago. Briefly, BBR makes an initial estimate of the delay-bandwidth product of the network path, and then drives the sender to send at this rate for 6 successive RTT intervals.
