Traffic in Japan

Source: http://www.soumu.go.jp/main_content/000316564.pdfBroadband (FTTH, CATV, DSL, FWA) download traffic at

2,892Gbps (1.27x from past year)Mobile traffic is 621Gbps (1.48x from past year)


Major Tokyo Peering Facilities and Exchanges

• KDDI Otemachi (a.k.a Telehouse Tokyo)– JPIX

• Equinix TY2– EIE, JPNAP, JPIX, BBIX

• NTT Data Otemachi– BBIX, JPIX

• Arteria Com Space I– BBIX, EIE, JPIX


Where are all the ISPs?

• Many regional ISPs seem to be present at ComSpace I with a few in MDA Otemachi

• Many large ISPs are still present at NTT Com Otemachi (a carrier building), and may have a POP or 2 at the previous page

DISCLAIMER! This is how I view this and may not describe the whole truth


Issues with selecting a POP in Tokyo

• Which facility should I go to?– TY2 has all the IXPs, but it’s full (and quite small)– Many local ISPs do not have presence in TY2

• Which IXPs should I connect to?– 3 ‘carrier neutral’ but telco owned IXPs + Equinix– There’s no ‘the one IXP that everyone connects to’

• Dark fiber?– NTT East owns a great share of the fibers, but you will not be

able to buy from them directly in most cases (unless you’re a local registered service provider and have the proper resources to contract with them)

– MDA, KDDI, Arteria, KVH, and some others may be able to provide dark fiber


Interesting operational practices

• MD5 still popular for BGP sessions• AS-PATH filtering still popular on peering sessions, and…

– Some people announce as-path updates to IXP participants’ mailing list

• Everyone is keen to announce planned maintenance notices– Some send announcements to IXP participants’ mailing list– If you don’t announce it, you may get e-mails asking if there

was an outage• Best to avoid maintenance on the 1st business day of the

month– Mobile data package allowance renewed


Interesting operational practices

• English peering requests are sometimes ignored– But this has improved drastically in the past few years

• BGP BFD quite popular– IXPs are metro fabrics on multiple buildings– Local content providers require short downtime, since

games communicate with servers real time• IXPs do not handle LACP (yet)• Most IXPs have a glimmer glass type fiber switcher• Each IXP has unique route server features– To be able to control who to advertise what prefix etc


Terminology

• “LOA” not so common

• Terminology “Private peer” (pronounced purai-bait-o pia) familiar but PNI not so familiar

• “Settlement” word not common. “Free peer” or “Paid peer”


Peering Ops communities

• JANOG and regional NOGs– Open to everyone. JANOG usually January and July

• Peering in Japan BoFs (began 2012)– 1-2 times a year at JANOG or Internet Week(usually

November)– Google groups list. Limited to IX participating AS

operators only• CloudIX group– BBIX participants working together under NDA

• IXP users’ meetingsUnfortunately most are Japanese language focused


Challenges for Japan today

• Facilities: power, space, and network concentration balance not so good

• CLS concentration and CLS to POP fiber

• Fiber and 10G connections across facilities still quite expensive around most areas

• Communication with non-Japanese speaking operators

• More presence in Osaka recently, however it has its own fiber, peering facility challenges
