  • Publication number: 20180123927
    Abstract: A method for detecting loss of network packets based on SDN includes selecting a data stream on a network path where the network path includes a plurality of switches. Start marking packet and end marking packet are created by a controller and the start marking packet is inserted in the data stream flowing through the first switch. After a time interval, the end marking packet is inserted. The respective arrivals of the start and end marking packets are reported to the controller by each switch on the network path. An absolute packet value between the start marking packet and the end marking packet flowing through each switch is calculated and a ratio of loss of network packets is calculated. The network path is adjusted and optimized according to the network packet loss ratios.
