Hi
    I am working on CR-LDP at present and have the following doubt. To gurantee QoS to customer the LER in "domain A" should be able to negotiate the expected traffic parameters from it's neighbouring "domain b" which could be MPLS or non MPLS. If "domain B" is non MPLS then how does "domain A" go on to negotiate parameters with the peer router in the neighbouring domain as in the case of Integrated Services in RSVP. The SLA between the two is supposed to determine the maximum limit for the services but how is the actual usage determined by "domain B" LER. The scenario is depicted below:

        neighboring domain B (non MPLS)       |            My Domain A (MPLS)
                                                                 |        
                                                   Router    |     LER 
                                                                 |

The data is supposed to flow from domain B to domain A.
