Autoconfiguration of L3 network for large-scale IoT emulation testbed

We propose a method of constructing a layer 3 (L3) network that consists of a large number of virtual machines (VMs) for a large-scale IoT emulation testbeds by utilizing Hierarchical/Automatic Number Allocation Protocol (HANA). The L3 network consists of several subnets, and suppresses the number of MAC addresses that must be distinguished from each other. HANA releases a burden of an L2 switch, compared to a flat L2 network. In addition, a network failure is restricted to a subnet. HANA also simplifies configuration of VMs in each physical machine (PM) by making MAC addresses and names of the VMs common among the PMs. The method of constructing the L3 network by HANA provides researchers with a large-scale IoT emulation testbed, which is easy to construct and extensible, and supports multihoming and renumbering. Researchers can define VMs as IoT devices and cloud/edge/fog computing servers, and perform various experiments on the testbed.
