Abstract:
1. A computerized method for selecting an electronic communication path between a network equipment and a customer premise equipment (CPE), the network equipment comprising a timer and processor, the method comprising steps of: communicating with the CPE through a primary path by the network equipment and starting to time according to a retransmission timeout (RTO) value by the timer of the network equipment, wherein the path is an electrical wired path where the transmission of electronic data flows across; determining whether the recorded time reaches the RTO value by the processor; switching the primary path to a secondary path when the timer exceeds the RTO value; sending a heartbeat packet to the CPE through the primary path and the secondary path to obtain a first response time of the primary path and a second response time of the secondary path; comparing the first response time and the second response time with the preset RTO value; comparing the first response time with the second response time when either the first response time or the second response time is less than the preset RTO value; enabling a comparison count to add by one when the first response time is less than or equal to the second response time; determining whether the comparison count exceeds one or not; and switching the secondary path to the primary path when the second response time exceeds the first response at least twice in succession.
