synchronizing computers in a network

yct · 2004-04-18T03:06:06

Synchronizing computers seems to me essential in every network game; however i haven''t found an article that explains how to do it. For example, I need to know whether some event in computer A happened before some event in computer B. As I don''t know how long it takes a packet to be transmitted between the computers, I can''t figure out a way to do it. Any idea?

hplus0603, are you talking about synchronization using NTP? If so, then where can I learn how to set up NTP server and clients in my LAN? (I use C++) If not, then how should the clients synchronize with the server?

There''s free source available too.

NTP is too heavyweight for something like this -- it requires you are on the Internet to find a nearby NTP server, and it requires a fair bit of time before it gets accurate. It also suffers from the problem that all the hosts are synchronizing to a remote server, and therefore have some degree of error.

Here's a simpler method.
