Hi Xuehui,
 
They are different.
The "linear protection switching protocol messages" are defined in the mpls-tp linear protection switching document.
The "protection switching event message" is a new message for shared mesh protection.
We will define its format and contents in the next version.
 
Regards,
Taesik

Hi authors, 

section 3.5.1 in your draft: 
If an end node of a working path detects a failure condition, it 
 triggers the protection switching by exchanging linear protection 
 switching protocol messages with its peer end node at the other end 
 of the working/protection path. 

 At the same time, the end node notifies its protection state change 
 to SENs by sending a protection switching event message. 

My question is whether the protection messages in these two paragraphs are the same or not? 

Best Regards
