Abstract:This research study, Mobile Networks in IPv6 with VOIP, was conducted at the United States Naval Academy (USNA) with the end goal of testing the capabilities of IPv6 in low bandwidth networks. Specifically, this study focused on the effects of using IPv6 on networks whose speeds are comparable to 56K Dial Up access, ISDN, and various other low bandwidth wireless networks. The first segment of this research project aimed to examine the feasibility of sending large amounts of data from high to small bandwidth networks. A significant portion of this project aimed to correlate MTU settings and transmission speeds. A hypothesis to be tested aimed to see if increasing or decreasing the MTU size would affect those speeds, but enough data was collected which showed that changing the MTU size only affected error rates, not transmission speeds. Tests were conducted to determine how line conditions would affect the way IPv6 would be transmitted across networks of varying bandwidth but extensive tests were unable to be conducted since legacy hardware was not able to be acquired. To help mitigate the hardware gap, a three-pronged approach of theory, simulation, and experiment setup was used to validate results. The second segment of this research project focused on the viability of incorporating separate IPv6 networks tunneled through existing IPv4 connections. Our recommendation to have a tunneled network is derived from the impracticality of completely transitioning over to IPv6 without having a “stepping stone” in case there are design flaws or the lack of personnel to support such a colossal move. The research shows that this is a more palatable concept for future development as only simple knowledge of implementing a tunnel and appropriate hardware compatibility are required.
