This paper optimizes the scheduling and routing of the co-flows of MapReduce\nshuffling phase in state-of-the-art and proposed Passive Optical Networking\n(PON)-based Data Centre Network (DCN) architectures. A time-slotted Mixed\nInteger Linear Programming (MILP) model is developed and used for the\noptimization with the objective of minimizing either the total energy\nconsumption or the completion time. The DCN architectures include four\nstate-of-the-art electronic switching architectures which are spine-leaf,\nFat-tree, BCube, and DCell data centres. The proposed PON-based DCN\narchitectures include two designs that utilize ports in Optical Line Terminal\n(OLT) line cards for inter and possibly intra data centre networking in\naddition to passive interconnects for the intra data centre networking between\ndifferent PON groups (i.e. racks) within a PON cell (i.e. number of PON groups\nconnected to a single OLT port). The first design is a switch-centric design\nthat uses two Arrayed Waveguide Grating Routers (AWGRs) and the second is a\nserver-centric design. The study also considers different traffic patterns\ndefined according to the distribution of map and reduce tasks in the servers\nand data skewness.\n
