Vivien and all,
AFAIK, PSC stands for "Protection State Coordination" in the MPLS-TP 
parlance (see MPLS-TP Survivability 
Framework<http://datatracker.ietf.org/doc/draft-ietf-mpls-tp-survive-fwk/>)  
- a new fancy name for what has been known as "APS Protocol" in SONET/SDH.

As you've noted, it has a completely different meaning in GMPLS.

Since GMPLS is going to be used with MPLS-TP, double usage of this acronym 
looks highly problematic.

Regards,
     Sasha

Dear Experts,

I'm surprised to find the term "PSC" used in this draft. I suppose the 
authors are talking about data plane not control plane, right? Isn't PSC in 
GMPLS elaborated as "Packet Switch Capable" ? It's confusing :-(
