Abstract: A frame processing method and apparatus are provided, to implement selective receiving in a redundant transmission scenario. According to a method, a destination device receives a first Ethernet frame from a first intermediate node through a first interface, where the first Ethernet frame includes a first time point, and the first time point is a processing time point of the first Ethernet frame on the first intermediate node. The destination device receives a second Ethernet frame from a second intermediate node through a second interface, where the second Ethernet frame includes a second time point, and the second time point is a processing time point of the second Ethernet frame on the second intermediate node. The destination device determines, based on the first time point and the second time point, whether the second Ethernet frame is a duplicate frame of the first Ethernet frame.
