  • Publication number: 20170220250
    Abstract: Embodiments of the present disclosure generally relate to a cloud computing network, or datacenter network, and a method of transferring information among processing nodes in a cloud computing network or datacenter. The network may include a hub that is coupled to a plurality of nodes so that data is transferred between nodes through the hub. Data from different nodes may be written into a slot within the hub, read, and then written into a slot within the destination node. Due to the proximity of the nodes to the hub, or even due to the amount of data to be written, the data may be written at different clock phases. The read may occur one or more clock cycles after the data has been written into the hub.
