OpenFlow Mesh Based Virtual Crossbar Network

Recently, in cloud computing, the power consumption is one of the most important topics. The power consumption of ARM processor is smaller than popular x86 processors. However, because of no virtualization technology, ARM cannot be applied to cloud computing. ARM is suited for low power cloud, which does not virtualize hardware. However, even if low power cloud, network must be virtualized to provide it as a service on demand. In this paper, we propose mesh based scalable virtual network using OpenFlow. In this network, we employ crossbar switch to connect a node to any other node in mesh. Using crossbar switch, we can organize any group that consists of any number of nodes. The crossbar switch is controlled using OpenFlow. We construct a crossbar switch with Raspberry Pi, ARM single board computer. In this paper, we evaluate the performance of crossbar switch and verify its practicality.
