IPv6 Deployment in China
0 likes444 views
The document outlines the progress and challenges of IPv6 adoption in China's network infrastructure, highlighting government initiatives that promote its use, particularly in mobile internet and LTE networks. It notes that while around 30 million users are capable of using IPv6, the actual number of users is lower, and dual-stack configurations dominate the current deployment. The document also discusses support and upgrades in various network and data center sectors to enhance IPv6 functionality and interoperability with IPv4 services.
