Towards 60GHz wireless switching interconnect

In the era of cloud computing and high performance computing clusters, interconnection networks are in high demand and have many applications including data center networks. Typically, nodes of interconnects are placed in a closed room and are connected using a set of wires through one or more high-end switches with little or no reconfigurability to the interconnect. In this paper, we present a design of wireless switching interconnects using 60GHz technology. The Gigabit, point-to-point and extremely directional links in the 60GHz band are used to replace wired connections in such a network to provide flexibility and reconfigurability. We extend our previous investigation where a high level node placement technique was discussed to arrange nodes into a closed polygon. Here we present an initial design for exact arrangement and placement of the fat-tree nodes, suitable for small to medium size wireless switching interconnects. We argue that creating a completely wireless interconnect is viable, and present mathematical equations and a proof to support the claim.
