Claim 0:
1. A communication method, comprising:
extracting, by an optical module in a network device, a first indication signal carried in a packet transmitted to a first circuit of the optical module;
extracting, by the optical module, a second indication signal carried in the packet transmitted to a second circuit of the optical module;
determining, by the optical module, a delay based on the first indication signal and the second indication signal, wherein the delay comprises a delay generated when the packet is transmitted in the optical module; and
sending, by the optical module through a delay reporting interface of the optical module, the delay to an interface chip in the network device, wherein the interface chip includes at least one of a physical (PHY) layer chip and a media access control (MAC) layer chip.
