it makes multi-provider interoperability more difficult to achieve.
The intent of the draft is to propose a small, well-defined, set
of class types so that we can have consistent mapping of services
across provider network boundaries in the implementation of
end-to-end QoS.
Thanks, Wai Sum.

 Hi! Do you mean that with the existing MPLS-DS & MPLS-DS-TE
 mechanisms, end-to-end QoS can not be implemented ?

 As indicated in the section 4 of the draft, all of the real
 parameters that make up the "ClassType" are signaled 
 individually (existing or new TLVs) anyway. Then how does it
 matter, what we call them (Class-Type 0 or Class-Type 1) ??

 Infact, the draft itself indicates [last line of Abstract]
 that its primary purpose is to further improve the
 scalability through the introduction of ClassType. [Which is
 is being address by different existing & upcoming DS-TE
 drafts]. Therefore, I am not sure, what is being achieved
 by the standardization of this new concept "Class-Type" ?

 Thanks,
 sanjay
