64B/66B CODE STREAM SENDING METHOD AND DEVICE, AND 64B/66B CODE STREAM RECEIVING METHOD AND DEVICE

摘要

Provided are a 64B/66B code stream sending method and device, and a 64B/66B code stream receiving method and device. The sending method comprises: determining an insertion period, wherein the insertion period represents a period in which an OAM code block is inserted between Ethernet data packets in a 64B/66B code stream; inserting one or more OAM code blocks into the 64B/66B code stream according to the insertion period; and sending, to a receiving end, the 64B/66B code stream that carries the OAM code blocks. In the embodiments of the present application, an OAM code block can be inserted into a path-layer signal of an MTN, and OAM safeguarding can be performed on the basis of a 64/66B code stream.
