That doesn't make any sense to me. What do you mean by "on the network"? Is your claim that using UDP will somehow saturate a shared circuit between multiple subscribers? What's stopping the switch from just dropping excess packets for one destination?
- londons_explore 3y ago> your claim that using UDP will somehow saturate a shared circuit between multiple subscribers? Yes. And it isn't specific to UDP. Basically any file transfer will keep going faster till at least one network segment is saturated. At that point, if the server keeps sending data a little faster than a regular congestion control algorithm would allow, you will cause packets from other users streams to be dropped.
- Karrot_Kream 3y agoOkay so that's the same thing you can do with TCP or any other transport atop IP, so not sure what QUIC is doing special here. Congestion control is handled at the transport layer.
- hot_gril 3y agoI think the part not said here is that ISP routers have ways to throttle per-user throughput, but home routers do not. QUIC has its own congestion control, but if it didn't, that'd be a problem.
- Karrot_Kream 3y agoThanks that makes more sense.
