1 IPv6 Transition Issues - From operational point of view - March Ikuo Nakagawa, INTEC W&G

2 About this presentation Background :: This is the first survey of IPv6 transition issues from operational point of view What do do we we need to to think/worry about transition from IPv4 world to to IPv6 world? Goal :: Before the the transition to to IPv6 world: --Describe transition story --List issues up up --Brash up up technical and discussion items

3 Where do IP technologies exist? Home User PC LAN Access Routers PC(OS, App.) Auth. Servers Enterprise Network Enterprise System Printer Name Servers Firewall Web/Mail servers Private Servers Core routers Internet PE Router mobile Data Center Server clusters idc Mobile Phone SW PDA CDN Management System site VPN site Site System

4 View points of discussion Considering from following points of of view --Backbone Providers --Home Users, SOHO --Access Providers --Enterprise Users --Server/Hosting --New service/new model New model Home New service SOHO Access Access /Backbone Enterprise Servers

5 Transition Story (brief example) time Backbone providers Access providers Server/Hosting Home users, SOHO Enterprise users New service, New model?? We are here!?

6 Transition phases (example) IPv6 ratio 100% time phase-1 phase-2 phase-3

7 Considering transition phases Defining transition phases: phase-1, 2, 2, 3 Discuss transition issues for for each phases Initial deployment, v4:v6=9:1 Reachability/Availability Widely deployment, v4:v6=5:5 Quality/Stability/Functionality IPv4 is is historical, v4:v6=1:9 Cooling IPv4 down!! We CAN use IPv6 applications! IPv6 is as stable as, or more stable than now IPv6 is huge world! many v6 only services

8 Phase-1 Transition issues Backbone providers v6 aware Core/Edge routers IGP(OSPF/IS-IS) implementation Almost ready, but... Home users, SOHO Dual stack home routers Client OS (Windows XP?) Basic applications (Mail, Web, DNS) Access providers Tunnel service boxes (routers?) v6 access routers (PPP, DSL, etc...) Some solution exist, but... Enterprise users Firewall (basic functionality) Basic server applications Registration system (ex. DNS, etc...) Server, Hosting Server OS (Unix?.NET server?) Applications (Mail, Web, DNS) Management tools (MRTG, SNMP MIB) New service, New model What s happen?

9 Phase-2 Transition issues Backbone providers More and more stable Core routers Transition scheme, Dual/MPLS/etc... Scalable IGP routing protocol New mechanism for hierarchical BGP Home users, SOHO Dual stack home network Replacing OS/App. in a PC Plug&Play (auto config.) Mechanism for v6 only nodes Access providers IPv6 addressing scheme (policy/tech) BAS, RAS, RADIUS for v6 users IPv6 session from Whole sale access Database (DNS/accounting/billing) Enterprise users Firewall products (P2P/PKI/etc...) Operational mng./regist. systems Enterprise systems for v6 nodes v6 only phones/printers scheme Server, Hosting IPv6 load balancer (DNS faker?) cache/splitter boxes (products) Mgmt products (OpenView or others) Production service of CDN v6 New service, New model Cellular? Internet oven? Internet car? Internet cow? sheep?

10 Phase-2 : Translator is required Translator :: In In Phase-2, both both IPv6-only networks and and IPv4-only networks exist exist in in the the same same time. time. That That is, is, they they need need a a translator to to communicate each each other. other. v6 v4 v6.edu v4.com v? Translator v6 v4 dual.org site site site

11 For the Phase-3 Nobody knows what we we have to to do, to to reduce the the # of of IPv4 nodes or or IPv4 communications s /idcs transition is is not so so difficult. Home users will replace their PCs in in a few years. But... Enterprises original systems, or or vendor specific protocols may run, forever...

12 Conclusion There are are 6 view points in in this presentation: --Backbone providers --Home users // SOHO --Access providers --Enterprise users --Servers/Hosting --New services // New areas We defined brief IPv6 transition story (3-phases) from operational point of of view --Phase-1: initial deployment phase --Phase-2: widely deployment phase --Phase-3: cooling IPv4 down and we we discussed technical issues in in each phases.
