Abstract
A method of fault notification in a carrier Ethernet having the capability of generating and transmitting OAM packets having flag fields, comprises inserting a bit in one of the flag fields to indicate the presence of service-affecting information in the OAM packets, detecting the presence of the inserted bit at the end of a data path, and performing a service protection action in response to the detection of the inserted bit prior to parsing the information in the message. One type of service protection action is protection switching.
