Re: [PWE3] I-D Action: draft-shawam-pwe3-ms-pw-protection-00.txt

Andy,

An overarching question - SS-PW and/or MS-PW?

MPLS-TP does not say much about MS-PW and I am not sure whether or not 
they are needed.

In the case of SS-PW  the LSP are entirely congruent, so presumably your 
concern is bandwidth of the underlying LSP causing you to need to spread 
your repair across a number of LSPs and thus the LSP and PW repair are 
mutually exclusive - correct?
