[c-nsp] MPLS DiffServ Tunneling Modes -Pipe mode

[Vitkovsky, Adam]

I was just checking the Cisco IOS Multiprotocol Label Switching Configuration Guide, Release 15.0M.pdf
For the IETF standards based DS-TE -and kept reading further about the Tunneling modes and that's where it got interesting

They are referring to Pipe mode as QOS Tunnel that goes form CE to CE
And indeed by that they mean that at ingress the managed CE should impose an explicit null-label with the EXP set accordingly on packets sent to PE
Than PE should refer to that EXP marking from CE to set the EXP marking towards the P-core

-just would like to ask the community whether this is now understood as the part of the pipe-mode setup
-cause I've always understood the pipe mode as PE-to-CE egress scheduling based on the mpls-exp values stored in the qos-group rather than the accrual ip dscp values
