摘要
随着互联网的迅猛发展，IPv4地址资源逐渐枯竭，IPv6作为下一代互联网协议成为必然选择，其过渡机制的研究对于实现网络平滑迁移至关重要。本研究旨在深入探讨IPv6过渡机制在网络迁移中的应用，通过文献综述与案例分析相结合的方法，系统梳理了双栈技术、隧道技术和翻译技术等主要过渡机制的原理、特点及适用场景。研究表明，双栈技术可使设备同时支持IPv4和IPv6，确保新旧协议共存；隧道技术能将IPv6数据封装在IPv4中传输，解决异构网络互联问题；翻译技术则实现了IPv4与IPv6报文直接转换，保障业务连续性。创新点在于构建了一个综合评估模型，从安全性、兼容性、成本效益等多维度对不同过渡方案进行量化评价，并提出了一种基于应用场景的混合过渡策略，为不同类型网络提供定制化迁移路径。该研究不仅丰富了IPv6过渡理论体系，还为实际网络部署提供了科学依据和技术支撑，对推动我国乃至全球IPv6规模部署具有重要意义。

Abstract
With the rapid development of the Internet, IPv4 address resources are gradually depleting, making IPv6, as the next-generation Internet protocol, an inevitable choice. The study of transition mechanisms is critical for achieving smooth network migration. This research aims to explore the application of IPv6 transition mechanisms in network migration by combining literature review and case analysis, systematically examining the principles, characteristics, and applicable scenarios of major transition mechanisms such as dual-stack technology, tunneling technology, and translation technology. The findings indicate that dual-stack technology enables devices to support both IPv4 and IPv6 concurrently, ensuring coexistence of old and new protocols; tunneling technology encapsulates IPv6 data within IPv4 for transmission, addressing interconnection issues in heterogeneous networks; and translation technology facilitates direct conversion between IPv4 and IPv6 packets, ensuring service continuity. An innovation of this study lies in the construction of a comprehensive evaluation model that quantitatively assesses different transition solutions from multiple dimensions including security, compatibility, and cost-effectiveness, and proposes a hybrid transition strategy based on application scenarios, providing customized migration paths for various types of networks. This research not only enriches the theoretical fr amework of IPv6 transition but also offers scientific evidence and technical support for practical network deployment, significantly contributing to the large-scale deployment of IPv6 in China and globally.
