19 IPv6 Address Allocation

20 C N G I-C PN Testing In September 2008, made testing of 100 CNGI-CPNs :00~ :00 Test Content CPN connectivity test CPN IPv6 DNS and IPv6 Web test CPN IPv6 users registration CNGI-CERNET2 backbone traffic monitoring

21 CPN Connectivity Test Get connectivity status, latency and packet loss of the uplink port of CPN by sending ICMP packets remotely by a test server 2001:da8:1:100::60 The URL of test server The result of testing 100% of 100 CPNs are available Minimum delay 0.3ms, Maximum delay

22 IPv6 DNS and IPv6 Website Test Set up a test server to emulate domain name resolution and wget process to CPN s DNS and website. The URL of test server The result of testing By the end of the testing all 100 CPNs IPv6 DNS and IPv6 website are available. However during the testing, many domain name

23 IPv6 User Registration Set up an IPv6 user registration website. When a CPN user visit this site, he will be asked to input a authentication code and an address (optional), then the server will generate an record which include user s IPv6 address and throughput to the server The URL of test server

24 Result of IPv6 User Registration As at :00 there are 387,022 different IPv6 addresses are seen by registration server There are 207,053 IPv6 addresses input correct authentication code

27 CNGI-CERNET2 Backbone Traffic During Testing During testing, The traffic of CNGI-CERNET2 backbone get a growth, which shows that to a certain extent, the testing plays a promotional role for IPv6

33 IPv6 D evelopm entproblem s Maturity issues of IPv6 products and technology Development problems of pure IPv6 network IPv4/IPv6 transition Promotion of IPv6 service IPv6 network management

34 Maturity issues of IPv6 products and technology Some of the IPv6 routers we ever used Juniper T640/T320/M20/M10 Huawei NE80/NE5000e Bitway BE12K Cisco CRS-16/8 CISCO 7609/6509 Hitachi GR4000 In comparison, it is some weak for IPv6 on the software maturity, research and development support and after-sale

35 Network Management Support Issues It is hard to measure IPv6 traffic because most of current router product don t support netflow v9 It is hard to acquire IPv6 MIB in pure IPv6 network because most of current router product don t support IPv6 SNMP

36 SNMP model in dual stack environment Can t survive in pure IPv6 network

37 Correct Understanding and Treatment of IPv6 Know 单击此处编辑母版副标题样式it, participate it, utilize it

38 Understand IPv6 Correctly Although Innovative Application is important to the development of IPv6, it is not the reason we choose IPv6 The core value of IPv6 is to solve the scalability problem of Internet One day in the future, perhaps in addition to the use of IPv6, we have no choice At present, the clever use of IPv6 networks can solve some practical
