  Passive Optical Data Centre Networks have been developed due to the
performance limitations in current data centres to provide high performance
within data centre networks. An AWGR based passive optical network data centre
architecture is evaluated using a TDM/WDM multiple access technique to
provision the flow of traffic among the network efficiently. A Mixed Integer
Linear Programming model is developed to optimise resource allocation in the
architecture. Using WDM-TDM as a multiple access technique helps in solving
issues such as oversubscription and congestion by allowing servers to make
simultaneous transmissions of packets in different time slots. The results show
that the provisioning / allocation of resource within the architecture is
improved with improvements of up to 75% in resource utilisation.
