摘要： Provided are a method and apparatus for transmitting error information between an Ethernet network and a synchronous digital hierarchy (SDH) network. According to the present invention, when an error occurs in the Ethernet network or the SDH network, OAM information is transferred to the opposite network by using a conventional MAC control frame from a linked part of the Ethernet network and the SDH network and thus the EoS network may be efficiently operated and managed. Also, by using standardized MAC control frame, the present invention may be applied to an existing system without additionally changing hardware or defining a new OAM frame.

摘要： Provided is a protection switching method via forwarding table correction in an Ethernet ring network. Upon detecting a failure in a link, a node generates a protection switching frame including an address list of a forwarding table corresponding to a port connected to the link, and transmits the protection switching frame to a port at an opposite direction of the link. A node that receives the protection switching frame deletes its own address from the address list included in the protection switching frame, and changes a port number of an address in the address list of the protection switching frame from among addresses of the forwarding table corresponding to a port that received the protection switching frame to a port number in an opposite direction of the port that received the protection switching frame or deletes the port number of the address in the address list.
