Top Forums Programming Would you please give me some idea about single client and multiple servers Post 302503982 by Corona688 on Saturday 12th of March 2011 09:31:59 PM

TCP timeouts can take entire minutes. Best-effort delivery and all that.

I'd try a simpler system using UDP. The client sends a 'hello' to a bunch of servers via one packet each then does recvmsg() in a loop until 200 milliseconds are up. Any servers that answered in time get considered.

As an aside, that 200 milliseconds requirement isn't quite sane. Many people and services use connections that have a higher minimum latency than that. Anything that's actually busy and not idle could add latency too.
