MULTIPLE-INTERFACE NETWORK DEVICE AND SELECTION METHOD FOR TRANSMITTING NETWORK PACKETS

摘要

A selection method for transmitting network packets adapted to be executed by a multiple-interface network device is provided. The multiple-interface network device includes a plurality of network interfaces. Each of the network interfaces connects to one of multiple communication networks. The selection method includes the following steps: collecting a transmission status of each of the communication networks; analyzing transmission characteristics of a predetermined number of packets of a service flow to determine a traffic pattern type of the service flow; comparing the transmission status of each of the communication networks with the transmission requirements of the traffic pattern type of the service flow to select one of the network interfaces, and using the selected network interface to transmit packets of the service flow. The service flow is constituted by packets transmitted by the network interfaces through a port and packets received by the network interfaces through the same port.
