SDN PACKET LOSS LINK DETECTION METHOD IN MULTICAST OF SDN

摘要

The present invention proposes a multicast packet loss location detection method on the SDN. According to another aspect of the present invention, Reporting the packet loss to the controller when the lost packet is found; The router generating a Fake packet having the same sequence number as the checked lost packet; Transmitting the Fake packet so that the router considers that the lost packet is normally received to a lower router after the router; It is possible to detect the multicast packet loss location on the SDN. Thus, the packet loss location can be grasped during data transmission in a multicast manner.
