Abstract
A method of protection switching in a packet network based on signal/service degrade includes monitoring a packet network connection; detecting the packet network connection has a signal/service degrade including a condition where the packet network connection is operational, but experiencing errors below a threshold; and responsive to detection of the signal/service degrade one or more of notifying nodes in the packet network and performing a protection switch based on the signal/service degrade. The signal/service degrade is detected through one or more of i) determining a Frame Error Rate imputed from one or more of Bit Error Rate, frame events, and frame losses; ii) frame delay measurements; and iii) a combination thereof.
