Abstract

In response to the requirements of the Outline of the 14th Five-Year Plan for National Economic and Social Development and the Long-Range Objectives Through the Year 2035 and the implementation of the Action Plan for Promoting the Large-Scale Deployment of Internet Protocol Version 6 (IPv6), the company launches a full-scale IPv6 upgrade and transformation across the network to accelerate the large-scale deployment and application of IPv6 in the education system. Aiming at the demand for smooth transition of two-site three-center data centers on the premise of ensuring service continuity, the company conducts a comparative study on IPv6 tunneling technology and VPN technology. The company finally adopts strongSwan, an open-source IPsec solution, combined with 4over6 tunneling technology to build encrypted communication links between remote IPv4 data centers. Experimental results show that the encrypted channel constructed by this scheme provides higher security, better link quality and a higher data transmission rate and effectively solves the instability problems of cross-data center communication and large-scale concurrent transmission under IPv4 links. The integration of dual stack technology realizes the reuse of physical equipment and links and significantly reduces the cost of IPv6 transformation.
