Evaluating BDMS and DSTM Transition Mechanisms

Unfortunately, IPv4 and IPv6 are incompatible with each other. So, a transition mechanism is required during the time of migration from IPv4 to IPv6 networks. Bi-directional mapping system (BDMS) is one of the mechanisms reported in the literature to perform IPv4/IPv6 conversion whereas the dual stack transition mechanism (DSTM) is designed to perform IPv4 to IPv6 transition for IPv6 dominant network. This paper proposes the analysis of the difference between the BDMS and DSTM. We implement the BDMS and DSTM in order to study their behavior using different performance evaluation metrics such as RTT, EED, and Throughput. The OMNeT++ simulator is used to implement the BDMS and DSTM mechanisms. The simulation results in this paper show that, BDMS RTT, EED, and Throughput performance metrics are better than DSTM especially when small packet sizes are used.
