Hello Bruce and all others,
occasionally I write a program to send messages froma server to several clients.
Because connections are fragile and clients often gets disconnected, I let them send "Heartbeats" to the server every n seconds.
Client: "Can you hear me, mama?"
Server: "I can hear you, my darling!"
I don't want to clutter the networrk traffic with my chirping, otoh I want to keep up the contact as reliable as possible. And the more clients contact, the noisier it gets.
My question now is, what is a reasonable frequency for those messages?
Thanks,
Wolfgang
