The sooner IPv6 is deployed the more opportunities for Internet development ——Make ready for IPv6 applications ——shorten the IPv4/IPv6 transitional period ——reduce the complexity of (dual stack) Internet management and development costs

中兴通讯 ZTE CORP。 RATION Prospect for IPv6 in China Need strong support from the government -Killer applications are still under development Set up IPv6 trial networks Collect operational experience before transitioning to commercial networks(New applications business model in IPv6 networks.) This is just what is being done in China +Build IPv6 network as a part of nGn Not just IP, we should have a much broader view 2003-4-9 Page 4

2003-4-9 Page 4 Prospect for IPv6 in China Need strong support from the government —— Killer applications are still under development Set up IPv6 trial networks —— Collect operational experience before transitioning to commercial networks(New applications, business model in IPv6 networks…) —— This is just what is being done in China Build IPv6 network as a part of NGN —— Not just IP, we should have a much broader view

中兴通讯 ZTE CORP。 RATION Early deployment of IPv6 should be mainly in mobile networks tThere are large IPv4 investment in fixed networks Smooth transition to IPv6 is a problem tMobile and Wireless internet is in its early stage of development Is growing rapidly Mobile support in IPv6 is much better than in IPv4 - IPv6 provides large enough address space 2003-4-9 Page 5

2003-4-9 Page 5 Early deployment of IPv6 should be mainly in mobile networks There are large IPv4 investment in fixed networks —— Smooth transition to IPv6 is a problem Mobile and Wireless Internet is in its early stage of development —— Is growing rapidly —— Mobile support in IPv6 is much better than in IPv4 —— IPv6 provides large enough address space

中兴通讯 ZTE CORP。 RATION WLAN+Mobile ipv6 +WlAN has many advantages as apposed to wired lan Easy installation much flexible Low maintenance and management costs Large potential market for WLAN +Mobile Ipv6 will enlarge the usefulness of WLAN - No need to change IP address while roaming More flexible networking scheme 2003-4-9 Page 6
