One doubt regarding the Ietf-draft-pwe3-cesopsn.
According to the latest versions ( 04/05/06/07 from March 2006) the PSN, Multiplexing and CESoPSN Layers foresee the CESoPSN control word just before the RTP fields and the Payload area with the exception of IPv4/v6 and UDP (Figures 1a, 1b and 1c). In this case the CESoPSN cotrol word is after the RTP fields and just before the Payload Area.
Seeing the Signaling Packets PSN, Multiplexing and CESoPSN layers instead the control word is just before the RTP fields and the payload area only for the MPLS case; in the IPv4/v6 and L2TPv3 and in the IPv4/v6 and UDP cases the Control word is after the RTP field and just before the Encoded Ce application state (Figures 4a and 4b).
So regarding the new definitions and the IPv4/v6 and L2TPv3 case we have a different relative position of the RTP and CESoPSN control words in Signaling Packets compared to payload Packets.
 
Thank you for comments.
