 A number of companies working in the SONET area already use or are
 planning to use DCC for IP control plane [I put MPLS list back ;),
 since this question is related to GMPLS and OTN-related work].

 There are two types of IP encapsulation on DCC that I know of:
 LAP-D and PPP/HDLC. We use the second one in our SONET products.

 I think writing up an IETF document describing this would make sense.
