Hybrid approach for migration of IPv6 to IPv4 Network for enhancing security in Virtual Private Cloud

Abstract

Internet Protocol version 4 (IPv4) addresses are now in short supply. Because of IPv6's strong features and limitations, many Internet Service Providers (ISPs), researchers, and end users are transitioning from IPv4 to IPv6. For ordinary users, many tunnelling strategies have been used to move to IPv6. These strategies, on the other hand, produce a slew of challenges, including compatibility, complexity, connectivity, and traffic. Because devices do not support IPv6 addresses directly, they are unable to connect with each other due to the distinct header structure and incompatibility of IPv4 and IPv6. The network's performance is also being harmed as a result of the massive increase in data transmission volume. In this study, we suggest merging two tunnelling approaches, IPv6 Rapid Deployment (6RD) and Teredo, to give complete IPv6 connectivity while also improving network performance. Jumbo frames are used to carry large amounts of data to boost network throughput. The primary goal of combining the two methodologies is to create a hybrid network rendering that supports full IPv6 connectivity. Not only does the suggested solution support IPv6, but it also improves network performance. According to simulation results, throughput and packet delivery ratio increase by 9000 bytes and 98 percent, respectively.
