Hello,
How could I send a broadcast TCP/IP message to all registered clients
at a server so that they begin to send any kind of data to server
sinchronously ?
Multicast would be good, but seeing as how the clients are "registered" how
about sending a UDP broadcast to a port of theirs that they've previously
told you about when they registered with the server on the TCP/IP
connection?
best regards
Cheers Richard Maher
Hello,
Assume that the server knows everything about clients (linked list
whith IP, Port, etc.) how do I generate an UDP Broadcast ? I read in
internet that in C# it works in the same way like unicast message only
broadcast IP should be entered, it is similar in Java ?
Or should I use java.net.DatagramSocket respectively
java.net.MulticastSocket ?
Thank you
Just read the docs for MulticastSocket and it will show you how to make
it work. The only real difference from a DatagramSocket is that you
join the group you want to listen to, that is that you pick an IP
address and port (not necessarily your address) and open the socket.
Any broadcast to that IP and port will be caught.
