METHOD AND DEVICE FOR TRANSMITTING AND RECEIVING OTN OVERHEAD

摘要

Provided are a method and device for transmitting and receiving an OTN overhead. The method comprises: performing physical layer encapsulation on a data message to be transmitted, and adding a type field during the physical layer encapsulation, so that different types of data messages can be time-division multiplexed in a physical layer channel of an OTN overhead, the type field being used for indicating the type of the data message to be transmitted; and transmitting the data message which has been subjected to physical layer encapsulation in the physical layer channel of the OTN overhead. The embodiments of the present invention can increase the use efficiency of a physical layer channel of an OTN overhead and realize the dynamic allocation for the physical layer channel, and can also expand the types of data messages.
