Programs: Day 1 - 2010.07.08(Thu)

We tried DNSSEC

Presenters

  • Masato Minda (JPRS)
  • Kazuma Hamaguchi (NTT Com)
  • Masanobu Kawashima (NEC AccessTechnica)

Abstract

We had some technical verification testswith some ISP players and hardware vendors to activate DNSSEC smoothly. In the tests, we built a DNS Tree from a root to clients and confirmed if the test DNS system worked well with DNSSEC technology.

We'll share with our experience and we would like to share the following points in the session.

  • Load of DNS servers
  • Operation
  • Any other to be changed by DNSSEC

Presentations

Thinking IPv4 in an era of IPv6

Presenters

  • Tetsuya Innami <chair> (BBIX)
  • Yasuo Kashimura (Alcatel-Lucent Japan)
  • Satoshi Ogawa (Cisco Systems GK)
  • Miya Kohno (Juniper Networks)
  • Satoru Matsushima (Softbank Telecom)

Abstract

Recently the topic of IPv6 deployment by ISPs and access providers has been very common. Having said that, demands for IPv4 Internet will continue.

Given this situation, we're thinking about how IPv4 services using an IPv6 native access network would work. First, we will introduce some technologies which provide IPv4 service offerings on top of an IPv6 infrastructure. Then, we'd like to open up a discussion with the audience.

Presentations

Making Fallback Work

Presenter

  • Yoshinobu Matsuzaki (IIJ)

Abstract

Nodes have only a vague image of the internet while they communicate with other nodes, but they work very hard to deliver packets reliably. For example, they may measure the path MTU and try to adjust the maximum packet size, or if IPv6 does not work try falling back to IPv4. In the operational world, we try to avoid fallbacks because they cause latency. One of the techniques we use is overwriting the TCP MSS. However fallback is the last resort in achieving successful communication. In order to make fallback work, the nodes, and also the network, need to make significant effort. We will discuss the problems that have occurred, and also discuss about what kind of network and node behavior is expected.

Presentations

Blocking

Presenter

  • Ichiro Mizukoshi (NTT East)

Abstract

Some of you might have seen the term "blocking" on the internet. Blocking is a technical measure intended to restrict access to certain content based on prepared lists by means of "DNS poisoning" or "proxy" etc. Blocking access to child pornography on the internet is currently under discussion in government ministries and providers. Let us discuss "blocking" as network operators.

Programs: Day 2 - 2010.07.09(Fri)

IXP Session - directly bridging your packets toward the destination

Presenters

  • Moderator
    • Shingo Kudo (Softbank Telecom)
  • Panelists
    • Kazunobu Ochi (BBIX)
    • Daisuke Touda (Internet Multifeed)
    • Masataka Mawatari (Japan Internet Exchange)

Abstract

If you are a engineer in the network design and operations group at an xSP, you probably know what IXPs do. But, you may not know all of the details.

At recent JANOG meeting, there was no presentation discussing technical details of IXPs. If your AS does not currently connect at an IX, we would like to talk and discuss with you IX technical issues, including other than layer two technology, which we think might be useful to you.

This presentation agenda is as shown below.

  • Latest IX situation,
  • Recent customer requirements,
  • Topics: Reliability, Services, Wide-area distribution
    • The problems that we're dealing with today
    • New challenges for us, and
  • Something else!

The Inside of My Toolbox

Panelists

  • Hiroyuki Ashida (ITSCOM)
  • Yukihiro Kikuchi (Brocade Communications Systems)
  • Toshiaki Baba (HEARTBEATS)
  • Tsutomu Sano

Abstract

As we all remember, we had an aggressive discussion about "tools" on JANOG mailing list recently. This session is to extend this discussion further and share it with the audience. A Panel which is composed of experts from broad areas (server, network, kitting and web development), will introduce various useful tools. Not only hardware tools but also software tools will be covered. Choosing the right tool will make our life much easier!

The Delusion about Internet Infrastructure

Presenters

  • Akimichi Ogawa (Geekpage.jp)

Abstract

About a present fixed charge system and the limit, and the delusion about the possibility of shifting to the following amount account. A big criticism is received in every case though the following amount account material was occasionally spoken from the first half of the 2000's. It is scheduled to speak including the change in the infrastructure environment in recent years. The fixed fee is hoped for as an individual user. However, the difficulty exists when the story of the person related to the infrastructure is heard. At present, the schedule is undecided. There is a possibility of becoming of the announcement the neighborhood and changing the content. Please note it.

Undersea cables - Stories about constructions and operations of it

Presenters

  • Yasuyuki Hamada (NTT Com)
  • Masahiro Nakajima (NTT Com)

Abstract

  • Facilities for Undersea cable systems
  • Maintenance and operation
  • Introduction of working systems

Presentation

Things You Should Know Before Saying "We Don't Need 'dot-Nippon'"

Presenters

  • Yoshiki Ishida (JPIX)
  • Kunihiro Tanaka (Sakura Internet)

Abstract

Many people may think we do not need Internationalized Domain Names, especially .日本 ('dot-Nippon'). However, shouldn't we understand the historical/global background and requirements from different view-points before we say "No" immediately?

Then let's reconsider how 'dot-Nippon' should be for Japanese Internet community. It's not too late to say "No," but after the discussion.

Presentation

More challenges on IPv6 Home Router ~What is the best addressing scheme for home network~

Presenters

  • Yoshiaki Kitaguchi (Kanazawa University / IPv6 Promotion Council)
  • Akira "SEBONE" Nakagawa (Japan Internet Exchange Co. Ltd. / IPv6 Promotion Council)

Abstract

IPv6 home routers, AKA CPE or HGW, are being talked about more often than ever. The IPv6 Promotion Council has been discussing this topic. In this session we will share the current status of the discussion at the IPv6 Promotion Council with JANOG members and hear your opinions about some challenges we are working on.

Presentation

IP addresses: Way forward

Presenters

  • Shishio Tuchiya (Cisco Systems)
  • Tomoya Yoshida (NTT Communications)

Abstract

The remaining free IPv4 address pool is now less than 7%. An IPv4 address block, 1.0.0.0/8 was allocated to APNIC by IANA in Jan, 2010. As you may recall, this allocation received some attention by the technical community and discussed in the JANOG mailing list due to possible reachability issues. Some of addresses within this /8 have been used as “RFC1918” addresses for internal networks and it contains more bogon addresses by comparing to other address blocks.

With reflecting such circumstances, we conducted reachability tests for 1/8 and 27/8 address blocks with APNIC’ cooperation.

This presentation will re-focus on issues of 1/8. This presentation will also share the above tests’ outcomes and current condition of bogon filtering. We would like to have discussions over such issues and also future counter measures.
