IPv6 - future approval networking

For the increasing demand on Internet and global IP mobility, IPv6 (Internet protocol version 6) has been designed as the next-generation Internet protocol to replace the currently used IPv4 protocol. The key enhanced features of IPv6, including IPv6 addressing, quality of service (QoS), IP security (IPSec), Mobile IPv6, possible transition scenarios and mechanisms, as well as the IPv6 deployment situations are summarized. Then, Nokia research activities for promoting the use of IPv6 in the Internet, the third-generation cellular networks, general packet radio service (GPRS), wireless LAN (WLAN) and home networks are introduced. Finally, an IPv6 cooperation program with CERNET (China education and research network) is outlined.
