摘要:
The present disclosure provides protection systems and methods for Ethernet ports. In particular, the present invention may provide a form of facility protection for any two facilities, located on any two cards. The facilities are provisioned as a protected pair and using automatic ITU-T Y.1731 control frames for control. In an exemplary embodiment, provisioning includes creation of an L2 protection service and associating it to a pair of facilities. One facility is identified as a working facility and the other as a protection facility. Under normal conditions (i.e., no facility fault), the working facility is in an active state and not conditioning while the protection facility is in a standby state and transmitting conditioning to subtending equipment. If a facility fault is detected at the working facility, then the working facility transmits condition Remote Fault (RF) and the protection facility removes it's transmit conditioning and becomes the active facility.
