5G SA网络引入IPv6的思路探讨

 

 

摘要：针对5G 独立组网（SA）网络引入IPv6，分析了5G SA用户面引入IPv6单栈的可能方案，特别提出了一种新型的基于IPv6单栈技术方案，详细介绍了其中的总体结构、冗余备份、端口映射和溯源方式等。相比于传统的双栈技术，新的技术方案不仅解决了终端地址不足问题，还有利于降低网络维护的成本，符合网络的发展趋势。最后，本文提出了运营级网络选择演进路线的策略建议。

Abstract: Focusing on the issue of deployment of IPv6 in 5G standalone (SA) network, different solutions of introducing IPv6 into 5G SA user plane are illustrated. In particular, a new IPv6-only solution is introduced, including its overall architecture, redundancy, port mapping and traceability solutions. Compared with the traditional dual-stack approach, the new one not only solves the problem of terminal addresses shortage, but also helps to reduce the cost of network maintenance, which is in accordance with the trend of the network development. In the end, a strategy proposal for the carrier-grade network to choose the migration path is proposed
