SELECTIVE ROUTING OF DATA TRANSMISSION BETWEEN CLIENTS

摘要

A method for selective routing of data transmission between clients is provided to select a better communication channel from a direct P2P channel and a relay channel according to routing hop counts of the pats. The method obtains a first routing hop count from a first client to a second client assuming a direct P2P channel therebetween, a second routing hop count from the first client to a relay server assuming a relay channel through the relay server, and a third routing hop count from the relay server two the second client assuming the relay channel through the relay server, and compares the sum of the second routing hop count and the third routing hop count with the first routing hop count. The method then selects a better data transmission channel from the direct P2P channel and the relay channel between the first client and the second client based on a comparison result. Also disclosed is a system using the method for selective routing.
