Major Tokyo Peering Facilities and Exchanges • KDDI Otemachi (a. k. a Telehouse Tokyo) – JPIX • Equinix TY 2 – EIE, JPNAP, JPIX, BBIX • NTT Data Otemachi – BBIX, JPIX • Arteria Com Space I – BBIX, EIE, JPIX copyright (c) 2015 BIGLOBE Inc. 7

Where all the ISPs? DISCLAIMER! This is how I view this and may not describe the whole truth • Many regional ISPs seem to be present at Com. Space 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 copyright (c) 2015 BIGLOBE Inc. 8

Issues with selecting a POP in Tokyo • Which facility should I go to? – TY 2 has all the IXPs, but it’s full (and quite small) – Many local ISPs do not have presence in TY 2 • 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 copyright (c) 2015 BIGLOBE Inc. 9

Interesting operational practices • MD 5 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 1 st business day of the month – Mobile data package allowance renewed copyright (c) 2015 BIGLOBE Inc. 10

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 copyright (c) 2015 BIGLOBE Inc. 11

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” copyright (c) 2015 BIGLOBE Inc. 12

Peering Ops communities • JANOG and regional NOGs – Open to everyone. JANOG usually January and July • Peering in Japan Bo. Fs (began 2012) – 1 -2 times a year at JANOG or Internet Week(usually November) – Google groups list. Limited to IX participating AS operators only • Cloud. IX group – BBIX participants working together under NDA • IXP users’ meetings Unfortunately most are Japanese language focused copyright (c) 2015 BIGLOBE Inc. 13

Challenges for Japan today • Facilities: power, space, and network concentration balance not so good • CLS concentration and CLS to POP fiber • Fiber and 10 G 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 copyright (c) 2015 BIGLOBE Inc. 14
