Subject: [PWE3] How about PW Group Protection?

Hi all,

By far, PW Group ID defined in draft-ietf-pwe3-control-protocol has no real function. 
So we use it to do something.

When large numbers of PWs need to be protected, the system must monitor every PW.
Then CPU load will be very large, and the switching speed and the QoS will be influenced.

So shall we introduce the End-to-End PW Group protection? 

The PW Groups can be identified by PW Group ID. A PW Group can consist of the PWs 
with the same characters, e.g.the same PW endpoints etc. Only one or more typical PWs 
are monitored in a PW Group. According to detect a few PWs, the switching is 
originated between the Working PW Group and the Protection PW Group. It will 
enhance the switching efficiency and reduce the system burthen.

Do folks have comments about the requirement and the solution?

Best Regards,
Zhang
