MPLS and beyond
MPLS recognizes that small ATM cells are not needed in the core of modern networks, since modern optical networks () are so fast ( at 40 Gbit / s and beyond ) that even full-length 1500 byte packets do not incur significant real-time queuing delays ( the need to reduce such delays — e. g., to support voice traffic — was the motivation for the cell nature of ATM ).

MPLS and synchronous
For ATM networks, which define a physical layer that carries timing, the synchronous residual time stamp ( SRTS ) method may be used ; IP / MPLS networks, however, do not define the physical layer and thus cannot specify the accuracy of its clock.
