WAN links drop packets all the time and that is not a rare event.
- vbezhenar 7y agoEthernet does not drop packets for me. I guess that people who're using WAN don't care much about network quality, otherwise they wouldn't use it in the first place.
- SahAssar 7y agoWAN is not the same as WLAN.
- vbezhenar 7y agoThen I don't understand why are you saying that WAN is dropping packets all the time. That's not the case for me. It happens, but it means that my Internet is almost unusable and it's rare event. I'm pinging various websites from time to time (because I play online games and dropped packets is very dangerous) and those pings are just fine. Unless it's common occurrence to pass ping packets but drop data packets, that's not happening for me.
- SahAssar 7y ago> dropped packets is very dangerous It's not, they are re-transmitted just fine by TCP or over the protocol built on UDP. Anyway, dropping packets over WAN is just a fact. If you don't think it happens then you are lucky enough to be able to ignore it. If you also think it never happens on your LAN then either you have better networking than the best datacenters or you are relying on hardware and software so you never see it.
- vbezhenar 7y agoI did not state that it never happens. I'm aware how TCP works. It's dangerous because game becomes unplayable. My point is, packets do not drop regularly for me. It's an exception rather than a rule. Spending a significant amount of traffic for error correcting codes which won't be used is a waste. Proper network stack should not enable this mode until actual packet drops are observed and should disable this mode if packets stop dropping. If a lot of packets are dropping, it might be worth to put even more error correcting codes, to be able to recover from two dropped packets, and so on.
