IPv4向IPv6的转换和过渡是网络发展的必然趋势,据发改委通知,“十二五”期间互联网普及率将达到45%以上,IPv6宽带接入用户数超过2500万,实现IPv4和IPv6主流业务互通,IPv6地址获取量充分满足用户需求。2014年-2015年为全面商用部署阶段,开展IPv6网络大规模部署和商用,逐步停止向新用户和应用分配IPv4地址,推动实现下一代互联网全面商业部署。随着国内IPv6进程的加快,目前国内三家运营商中国电信、中国移动及中国联通已在14个省20个城市启动IPv6网络升级改造,固网接入市场迎来新的机遇。中国市场正在大量部署10G PON设备,各省份
The transition from IPv4 to IPv6 is the inevitable trend of network development. According to the notice of NDRC, the internet penetration rate will reach over 45% during the “Twelfth Five-Year Plan” period and the number of IPv6 broadband access subscribers will exceed 25 million to achieve the mainstream of IPv4 and IPv6 Service interworking, IPv6 address acquisition fully meet user needs. 2014-2015 is a full-scale commercial deployment phase of IPv6 network deployment and commercialization, phasing out the allocation of IPv4 addresses to new users and applications to promote the full commercial deployment of the next generation of the Internet. With the acceleration of the domestic IPv6 process, the three domestic carriers, China Telecom, China Mobile and China Unicom, have started IPv6 network upgrades and upgrades in 20 cities in 14 provinces and areas, and the fixed-line access market ushers in new opportunities. The Chinese market is massively deploying 10G PON devices in all provinces
