Abstract
A method and system for determining network latency between clients in a computer network, such as in a gaming zone environment. Each client determines the network latency between each other client via a ping, response, and response-response protocol. To this end, a first client places first time information such as a timestamp into a (ping) data packet and sends the packet to the second client, who places second time information into the packet, and sends the packet as a response packet back to the first client. The first client determines a first network latency based on its current time and the first time information returned in the response packet. The first client then sends the packet back to the second client as a response to the response packet. The second client determines a second latency based on the current time information at the second client and the second time information received in the response-response packet. For multiple clients such as in a gaming zone environment, each local client sorts the IP addresses of the other remote clients into sets of clients, and pings the remote client or clients in each set once per predetermined period, thereby distributing the pinging operation to balance incoming and outgoing network traffic.
