I believe this is simpler to implement assuming one is implementing both a client and server. I already have special case code to send a PING when there are bytes in flight but nothing to send, so this is very similar. I agree it's not necessary, but I find the simplification appealing, and when we first discussed this problem, no one suggested this solution, so I thought it was worth writing up. If we keep the existing text that the client has to keep sending, I'm not sure doing this on the server side is a valuable optimization, so I'd prefer to stick with one mechanism or the other. To me, the main negative is the server sending extra datagrams, as you said. And maybe that's enough to stick with what we have. -- You are receiving this because you are subscribed to this thread.
