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 copyright (c) 2015 BIGLOBE Inc.7

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 copyright (c) 2015 BIGLOBE Inc.8 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 copyright (c) 2015 BIGLOBE Inc.9

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 s asking if there was an outage Best to avoid maintenance on the 1st 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 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’ meetings copyright (c) 2015 BIGLOBE Inc.13 Unfortunately 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 copyright (c) 2015 BIGLOBE Inc.14
