IPv4 Routing over IPv6 Routing Data Plane Using SRv6

Segment Routing is a topic of interest in the field of networking and telecommunications, it is a source-based routing in a modern form rather than traditional routing. It comes with an innovative approach to integrating IPv4 routing and tunneling within the IPv6 data plane, utilizing segment routing technology. The implementation of this technique enables efficient and effective routing of IPv4 traffic over an IPv6 infrastructure, providing a solution for the near depletion of available IPv4 addresses. In this paper we discuss the design and implementation of the proposed approach, including the use of segment routing to create a virtualized network topology that supports both IPv4 and IPv6 traffic. The encapsulation method refers to the process of wrapping an IPv4 packet in an IPv6 header, allowing it to be transmitted over an IPv6 network. This process involves adding a new header to the packet, which contains information about the original IPv4 packet, such as its source and destination addresses, protocol, and the data itself. This modified packet is then transmitted over the IPv6 network, where it can be routed and delivered to its intended destination. This paper presents a solution for integrating IPv4 routing and tunneling within the IPv6 data plane using segment routing technology. This approach offers a practical solution to the challenges posed by the near depletion of available IPv4 addresses so we can join the existing IPv4 Island with existing IPv6 Island without the need to abandon the IPv4 completely, it also providing improved network performance and scalability. The findings of this research have important implications for the future development of networking technologies and the evolution of the Internet.
