Method and apparatus for transmitting error information between ethernet network and synchronous digital hierarchy network
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.
