The second DT issue is on the physical architecture which can be supported by GMPLS (from the draft):

ASON does not restrict the architecture choices used, either a co-located architecture or a physically separated architecture may be used. Some members of the Design Team are concerned that GMPLS's concept of the LSR requires a 1-to-1 relationship between the transport plane entity and the control plane entity (Router). They invite CCAMP input on GMPLS capabilities to support multiple architectures i.e. how routing protocols would identify the transport node ID vs. the router or routing controller ID when scoping Link IDs in a link advertisement.
