It's been a long time since I've paid attention to that world, but AFAIK, PEPs are still used and essential equipment for internet-style communication (i.e. TCP

  > they concluded that PEPs were not being used in the Starlink network That makes sense, given that they're probably most useful for high-latency networks. But what I find quite surprising is that Starlink does nothing about the 1-2% packet loss, as described in TFA; I'd really have expected them to fix that using an ARQ at a lower layer. Then again, maybe that's a blessing – indiscriminate ARQs like that would be terrible for time critical things like A/V, which can usually tolerate packet loss much better than ARQ-induced jitter. Thinking about it, that actually strengthens the case for PEPs: They could improve TCP performance (and maybe things like QUIC?), while leaving non-stream oriented things (like non-QUIC UDP) alone. Maybe Starlink just expects BBR to eventually become the dominant TCP congestion control algorithm and the problem to solve itself that way?
