    Presentation [ppt | pdf]

    This presentation describes methods to allow multiple services to coexist effectively in an IPv6 network and to ensure a range of network control policies, such as quality of service, authentication, and filtering. The presenter discussed the “one service, one prefix model” that has been proposed in IETF forums, noting that this model has a serious problem in source address selection (see RFC3484).

    The presenter then described a solution that has been proposed to this problem, based on new options for DHCPv6 and RA. This mechanism is now being standardised in the IETF DHC and IPv6 working groups.

    Questions and discussion

    • There was a question about the data to be added to a router advertisement to allow the selection of addresses to be handled by the end node. It was noted that this question has arisen before because the available information space is very small. It was noted that if there is too much data, there will be a fallback to DHCP and the source selection algorithm.
    • There was an explanation of the protocol to get source selection policy. It was noted that this proposal does not cover the authentication issues involved.
    • There was a question about address spoofing issues. It was explained that spoofing is related to authentication and is beyond the scope of this proposal. It was noted that DHCP itself has authentication mechanisms.

  3. IPv6 allocation status report

  4. Annaliza Mulingbayan, APNIC

    Presentation [ppt | pdf]

    The presenter provided an update of the APNIC and global IPv6 allocation statistics. IANA has now allocated four /23 ranges to APNIC, and has also made two very large allocations of /19 and /20. RIPE NCC has so far made the greatest number of IPv6 allocations. In this region, the majority of IPv6 allocations have been to Japan, Korea, Taiwan, and mainland China.

    In 2004, APNIC made a total of 53 IPv6 allocations. The presenter described the circumstances of the very large IPv6 allocations made, including a report on behalf of one of the providers, outlining their IPv6 implementation plan.

    APNIC has recently made an experimental allocation to WIDE Japan for a field test of IPv6 DNS services. The full project documentation will soon be made available on the APNIC web site.

    There was a review of the IX and critical infrastructure assignments made to date as well as the current state of database registrations.

    Questions and discussion

    • There was a comment that the chart comparing RIR allocations would be more useful if they presented the amount of address space allocated by each RIR rather than the number of allocations.
    • It was noted that one of the large allocations was made to NTT West, not NTT.

  5. ASIX6 status report

  6. Ethern MC Lin, Academia Sinica

    Presentation [ppt | pdf]

    The presenter explained the roles of NICI (National Initiatives for Communication and Information) and the Academia Sinica Computing Centre (ASCC) in Taiwan. In recent years, these organisations have focussed on projects related to the construction and promotion of commercial IPv6 services in Taiwan. The presenter reviewed the current architecture of the IPv6 services being developed under this project, including the ASNet Internet Exchange v6 (ASIX6). He presented the details of the current peering status at this exchange and noted that there are currently six members, with a seventh expected to join soon. He also discussed the global infrastructure of this exchange.

    The presenter also described architecture and functions of the M6bone and the TaipeiGigaPoP.

    Questions and discussion

    • There was a discussion about the traffic aspect of the network and the application development. Traffic is being measured in the ASIX6, but the measurements are available to members only.

  7. Large space IPv4 trial usage program for future IPv6 deployment activities – summary

  8. Kosuke Ito and Gako Hashimoto, IPv6 Promotion Council of Japan

    Presentation [pdf]

    This presentation continued a regular report on the progress of the large space IPv4 trial usage program in Japan, which is intended to promote IPv6 deployment activities. It was noted that participants have reported problems eliminating their need for IPv4 infrastructure, as reported in detail at APNIC 18.

    The presenters discussed case studies of several project participants, including developments in new services and relative demand for services such as phone applications, and public wireless LANs, and music services. It was noted that one of the project participants has now dropped out of the project.

    The project has had success in raising the ISPs’ motivation for moving to IPv6. There has also been success in developing a low cost operation scheme and IP address management tools. The tools are web based, open source applications that also link to the APNIC whois service. The tools also allow reverse DNS management.

    There will be a proposal in the policy SIG to extend the trial until 2008.

    Questions and discussion

    • There was a discussion of the savings in installation times for IPv6 phones as compared to IPv4 phones. It was noted that with IPv6, there is no need for a network technician to go on site with the phone technician, as the network settings can be made remotely. It was also noted that IPv4 phone installation is complicated by NAT.

    Action items
