Hotel Information

The following hotel is within walking distance from the venue and also has an english web page.

Beware, the hotel has nothing to do with JANOG, so if you want to ask for directions, ask how to get to "Nihonbashi Mitsui Hall". http://www.nihonbashi-hall.jp/ (Japanese)

Access Map is http://www.nihonbashi-hall.jp/pdf/map/access.pdf (Japanese)

The following hotel is most near from Nihonbashi Mitsui Hall.

Worries about internet routes

Presenter

• Naoki Mashiko, Chika Yoshimura (NTT)

Abstract

ISPs have to cope not only with the enormous traffic grow, but also with the increase in the number of full routes, which might cause unstable network behavior. If the current pace of increase continues, several problems such as RIB/FIB space shortage and longer routing convergence time may arise.

As of April 2011, a full internet routing table is about 344,000 prefixes for IPv4 and 5,000 for IPv6, but there are many causes of further increase in ISP's backbone network routes, such as:

1. After IPv4 IANA free-pool address exhaustion, minimum address allocation size has been changed (i.e. to /22 or to /24), hence many smaller address blocks may be advertised.
2. IPv6 prevalence
3. When introducing IPv6 in access networks, the number of small IPv6 routes may increase. These routes might not be advertised to the global Internet but still need to be handled in ISP's backbone network.

In addition, several routes which should not be advertised to the Internet such as private AS and AS-TRANS (AS23456) are often observed.

In this session, we would like to present the following topics:

• An analysis of currently observed Internet routes
• Some predictions about future routes
• ISP's worries about route increase and invalid routes, possible troubles, technical countermeasures
  • Effective measures against RIB/FIB space shortage
  • Troubles receiving invalid routes, pros and cons of filtering

Presumably non-ISP communication carriers (global AS user) have the same problem, so we would like to have an open discussion about better operations for the coming age of possibly massive routes.

Informal voices from a Layer 1 networking engineer

Presenter

• Tomohiro Onodera (Marubeni Access Solutions Inc.)

Abstract

This program is a introduction to the latest in Layer 1 networking.

• What do Layer 1 engineers feel and think while on the job?
• Physical layer technology to share with the other layer network engineers.
• Basic technical terms and current issues in Layer 1 networking.

I am offering a broad introduction to Layer 1 (technical talk, safety measures and other subjects).

What IT can do. - What should IT do in a emergency. How should IT respond.-

Presenter

• Makoto Takahashi (Softbank Mobile Corp.)
• Masafumi OE (The Astronomy Data Centre of the National Observatory Of Japan)
• Naoto Matsumoto (SAKURA Internet, Inc.)

Abstract

March 11, 2011, A earthquake struck and inflicted enormous damage on Tohoku district. There were a great number of victims and it is still vivid in our memory. In fact, many problems with the importance of IT infrastructure and restoration in an emergency were brought out during this disaster.

In this session, we will have three people on stage, discussing how should IT infrastructure should respond when facing a domestic emergency in the future, overall status of on-site reconstruction work and a means for transmitting information.

Was the Internet in Japan robust against the earthquake?

Presenter

• Yoshiki Ishida(Japan Internet Exchange Co., Ltd.)
• Hideo Ishii (PACNET Global (Singapore) PTE LTD.)
• Tomoya Yoshida(NTT Communications Corp.)
• Akiyama Nobuhiko(Nippon Telegraph and Telephone East Corp.)

Abstract

It is evaluated that the Internet in Japan was robust against the disaster of major earthquake in Mar 11. On the other hand, it was also said that the communication infrastructure including the Internet access in the disaster area was almost all impaired and the infrastructure in the circumference area including Tokyo metropolitan area was influenced and just barely survived in some phases.

In this session, we would like to discuss what we should do to make the Japanese Internet robuster against future disaster, while looking back what happened in the disaster of Mar. 11 in each phase.

JANOG update and open mic

Presenter

• JANOG committee

Abstract

In previous meetings, the JANOG update had been a unidirectional report made by the JANOG Committee. This time we will try also having time for discussion with JANOG members about the operation of JANOG, much like the open mic in the IAB and IAOC sessions in IETF meetings.

The JANOG committee will present its usual report first, then the the JANOG Committee members will appear on the stage and take comments, suggestions, and questions from the JANOG members. Topics might be the organization of management of meetings, collaboration/co-work with other communities, what activities could be valuable for JANOG, the required functions in JANOG, and so on. We would like to have frank discussions with you all.

Program: Day 2 - Friday, July 15, 2011

IX and 100 Gigabit Ethernet

Presenter

• Katsuyasu Toyama (INTERNET MULTIFEED CO.)

Abstract

The traffic on the Internet in Japan has been increasing. Many ISPs are connected to the internet exchanges using multiple 10 Gigabit Ethernet links. At the same time 100 Gigabit Ethernet is now ready to use as a much-anticipated faster interface beyond 10 Gigabit Ethernet. This session reviews 100GE technology and takes a look at the current situation of 100GE products. And network operators and engineers from vendors will discuss their concerns on deploying and operating 100GE in IX environment especially about the interoperability along with tangible data. We will also discuss what should be kept in mind of ISP operators when they deploy 100GE in future.

Summing Up World IPv6 Day

Presenter

• Yoshinobu Matsuzaki (Internet Initiative Japan)

  1988 joined IIJ, was in charge of the Internet Connectivity Service  
  2000 joined the backbone operation team
  2002- IIJ-SECT (IIJ Group Security Coordination Team) member
  2004- NSP-SEC-JP Moderator
  2007- APNIC IPv6 Technical SIG chair
  2008- The Asia Pacific Operators' Forum co-chair
  2011- Asia & Pacific Internet Association Director
   ...spending a lot of time to find something interesting and tackle with them

Abstract

World IPv6 Day was planned as a macro-scale trial of IPv6, mainly led by content providers. As a result, many service providers throughout the world examined the possible impacts of introducing IPv6, clarified the challenges, and figured out how to deal with it.

In this session, I'd like to reflect on World IPv6 Day, share the actions and challenges that various organizations had, and encourage everyone to discuss what future services should be.
