METHOD FOR MAPPING PACKET SERVICE TO OPTICAL TRANSPORT NETWORK, AND OTN DEVICE

摘要

Embodiments of the present invention disclose a method for mapping a packet service onto an optical transport network, including: receiving a packet service message from an access side, and identifying the packet service 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 packet service message to the first line board corresponding to the first board number; and encapsulating the packet service message that is sent to the first line board, mapping an encapsulated packet service 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. According to the foregoing technical solutions, 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 timeslot or a same ODU timeslot on a same line board.
