Sorry, I was confused by L-label in the last version and S-Label. But we still need to harmonize the T-Lable with the S-Label. For example, if we set up a low-latency or contention-free LSP for a detnet flow (between DA-T-PEs or DA-S-PEs), most probably we need some traffic engineered LSPs (i.e., L-LSP as defined in RFC 3270). Can we regard L-LSP labels on the path to be a T-Label or an S-Label?

As I remember, we had some consensus that PW label has carried enough information in the f2f discussion happened during the last IETF meeting. And S-label is regarded redundant for PW. Did I miss something?
