Abstract
The present invention is to provide a route selection method which is applicable to a network connection device capable of receiving or transmitting a network packet through at least two heterogeneous networks. Upon receiving the packet, the device performs route performance detection to obtain the current transmission delay rate of each of the heterogeneous networks, and then determines whether the packet is highly sensitive to transmission delay or has a re-transmission mechanism. When it is determined that the packet is highly sensitive to transmission delay or doesn't have the re-transmission mechanism, the device chooses from the plural heterogeneous networks the one with a relatively low transmission delay rate as the route through which to transmit the packet to the Internet; otherwise, the device chooses from the plural heterogeneous networks the one with a relatively high transmission delay rate as the route through which to transmit the packet to the Internet.
