Abstract: An Ethernet ring protection switching (ERPS) method and a node, where the method includes clearing, by a first node, media access control (MAC) address forwarding tables of a first ERPS port and a second ERPS port, and simultaneously changing multiple ports including the first ERPS port and the second ERPS port to a broadcasting state when the first ERPS port becomes faulty, where the second ERPS port is another ERPS port except the first ERPS port, sending, in a broadcasting manner using a port in the multiple ports, the MAC packet to a target node when a MAC packet is received, and changing the multiple ports to a forwarding state, learning a MAC address according to a broadcasting path of the MAC packet to obtain a target MAC address forwarding table of the second ERPS port. Hence, ERPS efficiency may be improved.

Abstract: 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.
