1. A method comprising:
configuring, by a device, a plurality of subinterfaces for each of a plurality of physical ports of a software defined network (SDN);
allocating, by the device, a fixed amount of bandwidth to each of the subinterfaces to construct a plurality of midlays for the SDN;
forming, by the device, the plurality of midlays by assigning subsets of the plurality of subinterfaces to each of the midlays, wherein the plurality of midlays operate as an intermediate layer between a physical layer of the SDN and an overlay layer of the SDN to implement network slicing; and
assigning, by the device, a network slice to one or more of the midlays, based on a bandwidth requirement of the network slice.
