Implementation of flexible network system with the grouping method by using VNIC and unique ID

Local area network is separated into some groups to ensure the security in company, university, and so on. This is generally implemented by using the function of a networking device. However, it is not easy for this method to change the network layout. In addition, there is a problem with compatibility of the device. This paper proposes a network system which has functions to group clients and to conceal communication data by using virtual NIC (VNIC) and hardware ID. This system is implemented by the computer software. The implementation by the software is able to solve the problems of the conventional method. We verify the effectiveness of this system through the result from experiments with this method.
