route compressed packets with MPLS labels PE1 --> PE2
packet decompressed at CE2 using cRTP algorithm
minimizes CE requirements (has to route HC context)
additional PE requirements (need to create ‘SCID routing tables’)
Issue 1 - PWE3 WG Charter Extension
VoMPLS header compression not within current charter of the PWE3 WG (or any WG)
seems the best fit
header compression historically a transport item (PWE3 in transport area)
header compression more a function of application than "base MPLS technology”
current charter mentions work on header compression with RTP: “Specify methods with RTP(and possibly using header compression where needed) to ensure in-order final PDU delivery, perform clock recovery inband emulation and maintenance functions across the PSN, where required.”
what extension needed?
PWE3 not chartered to do work related to signaling PE-PE tunnel (PW signaling/maintenance in scope)
proposals in I-Ds require extensions to RSVP-TE to create tunnels
