1. A flexible Ethernet (FlexE) communication method, wherein the method comprises:
receiving, by a first network device by using p physical layer apparatuses (PHYs) in a FlexE group, p first overhead blocks sent by a second network device, wherein the p first overhead blocks are in a one-to-one correspondence with p FlexE overhead frames, the p FlexE overhead frames are in a one-to-one correspondence with the p PHYs, the FlexE group includes n PHYs, n>2, and n is an integer, wherein
m PHYs in the FlexE group are in a faulty state, the p PHYs are in a normal state, p+m=n, 1≤m<n, and both m and p are integers;
storing, by the first network device, the p first overhead blocks in p memories in n memories, wherein the p first overhead blocks are in a one-to-one correspondence with the p memories; and
simultaneously reading, by the first network device, the p first overhead blocks from the p memories.
