APPARATUS FOR TRANSFERRING DISORDER BETWEEN ETHERNET NETWORK AND SDH NETWORK AND METHOD THEREOF

摘要

An apparatus for transmitting failure information between an Ethernet and an SDH network and a method therefor are provided to transmit OAM information to other networks using an existing MAC control frame in interfacing between an Ethernet and an SDH network when there is failure on the Ethernet or the SDH network, thereby operating and managing an EoS(Ethernet over SDH) network effectively. A frame transceiving unit(10) transceives an Ethernet frame through plural optical transceiving ports and detects the failure of a physical link. An MAC(Media Access Control) processing unit(20) reads the header information of the Ethernet frame received by the frame transceiving unit to detect an OAM(Operations, Administration and Maintenance) frame and status information by port, and generates an OAM frame using status information by port and transmits the generated OAM frame to the Ethernet through the frame transceiving unit. An SDH(Synchronous Digital Hierarchy) processing unit(30) receives status and failure information about the Ethernet to generate a corresponding SDH OAM frame. An output interface unit(40) receives the frame generated in the SDH processing unit and outputs the received frame to an SDH network. A signal processing unit(60) receives the failure information detected in the frame transceiving unit to generate a corresponding OAM signal, and transfers status and failure information on a network for generating the SDH OAM frame generation information from the OAM frame generated in the MAC processing unit to the SDH processing unit.
