multi player shared game state

In an online multi player game, data shared between clients is changing every 200 milli second.

A way to do that is to have the Server dispatch new events every this period with the updated data to notify all clients.

Would that be good way to do it, any performance issues? Or there is another way to achieve this.

this is up to your algorthm to make quicker or slower updates on network connections. 200 ms are affordable for an average speed of 56kbits/s… what is your problem ? ???
