摘要
A method for mapping a packet service onto an optical transport network is disclosed. An embodiment of the method includes: receiving a packet service message from an access side, identifying the message by using a first board number of a first line board in which a first egress is located and a first port number of the first egress; sending the message to the first line board corresponding to the first board number; and encapsulating the message that is sent to the first line board, mapping the encapsulated message onto a first optical channel data unit ODU corresponding to the first port number, and sending the first ODU by using the first egress. Cross-connect scheduling of any bandwidth in any direction is implemented based on a packet service, and packet services on different tributary boards share different ODU timeslots or a same ODU timeslot on a same line board.
