1 A Practical Approach to IPv6 Vietnam IPv6 Day Boonchareon Chong Global Solution Architect - Service Provider Boon@f5.com

2 The move to IPv6 The Data Tsunami in Service Providers and Enterprises IP Everything Multimedia devices Smart grid Machine-to-machine Video surveillance Multimedia Content Video on demand Cloud computing VoIP Social media F5 Networks, Inc 2

3 IPv6 Driven by Consumerization of IT 4.3B IP Address INFINITE 73% Penetration >90% Penetration 450M Smartphones > 800M Smartphones F5 Networks, Inc 3

4 What s your name?.. I Meant What s your IP Address? F5 Networks, Inc 4

5 IPv6 What it means to you.the Impact Service Providers Subscriber Acquisition Revenue Growth New Value Added Services Enterprise Consumer User Experience Launch of New Business Applications Encourage Enterprise Application Usage F5 Networks, Inc 5

6 What Can you Do The Approach? IPv4 Island IPv6 Internet IPv6 Dominate IPv4 Island IPv6 Island IPv6 Island IPv4 Internet IPv6 Island Transition IPv6&IPv4 Co-Exist IPv4 Internet (Getting ready for the rest of the world to be ready while IPv6 Internet maintaining business as usual) IPv4 Dominate F5 Networks, Inc 6

7 Moving To IPv6 Considerations Service Providers Subscribers Accessing the Internet Subscribers are issued IPv6 Addresses or/and Private IPv4 Wide Varieties of Subscribers Types iphone, Android, ipad, Smartphone, PC, Windows XP, Mac etc Not all are IPv6 or Dual Stack Enabled Should not affect and Transparent to Subscribers Existing Condition and Usability F5 Networks, Inc 7

8 What can you do Service Providers F5 Recommends To Start With NAT Dual Stack Tunneling NAT Pros Easiest green field deployment, Eventual Environment Pros Easiest Transport Solution No Application Awareness Pros No impact on legacy systems Seamless any device any app connection Cons Issues with Legacy applications and devices Too much to do at once Cons IPv4 and IPv6 environment isolation Too much Changes to the Subscribers devices eg Residential gateways need to be updated. NAT (eg NAT64 is still required regardless of tunnelling Need of ALG Cons Session and NAT density termination stress F5 Networks, Inc 8

9 IPv4 to IPv6 Subsriber s Migration Strategies Introduce NAT44 Enable Dual-Stack Migrate NAT44 to DS-Lite IPv4 address exhaustion IPv6 service introduction Gradual migration to IPv6 only architecture Introduce NAT44 Enable Dual-Stack Migrate NAT44 to NAT64 Phasing mainly driven by IPv4 exhaustion urgency and network equipment readiness F5 Networks, Inc 9

10 How about non-ipv6 friendly applications? e.g. Hardcoded IPv4 address within a page. ERROR: CONTENT NOT FOUND F5 Networks, Inc 10

11 F5 Application Fluent IPv6 Translation can fix non-ipv6 friendly applications F5 Networks, Inc 11

12 Real World Case Study Service Provider Approach With F5 F5 Networks, Inc 12

13 Mobile SP - Before Mobile Smart Devices 3G PC/Laptop HSPA/HSDPA 3G F5 Internet IPv4 IPv4(Pub) GGSN Traffic Steering Mobile Optimization F5 Networks, Inc 13

14 The Problem: Uncompleted request No more IPv4 to assign The Impact: Subscribers are unhappy because they cannot reach the Internet F5 Networks, Inc 14

15 The Fix with F5: - Assign Private IP to fix the current issue - NAT44 (NAPT, DNAT, PBA, IPBA, ALG) - Logging NAPT 2013-Feb-28 11:41: MSISDN: , IMSI: , C-IP/P: :30073, XIP/P: :33687, DIP/P: :53 PBA 2013-Feb-28 11:41: MSISDN: , IMSI: , C-IP/P: :30073, Assigned XIP/P: : for 10 minutes F5 Networks, Inc 15

16 We should do this progressively: Now - 10% Private, 90% Public 1 Week - 50% Private, 50% Public 1 Month - 100% Private, 0% Public F5 Networks, Inc 16

17 Mobile SP Broken Lets Fix It - Now Mobile Smart Devices 3G IPv4(Pri) IPv4(Pub) PC/Laptop HSPA/HSDPA 3G Destination IPv4 F5 NAT44 F5 Destination IPv4 Internet IPv4 GGSN Traffic Steering Mobile Optimization F5 Networks, Inc 17

18 Mobile SP After NAT44 1 Month Mobile Smart Devices 3G IPv4(Pri) IPv4(Pub) PC/Laptop HSPA/HSDPA 3G Destination IPv4 F5 NAT44 F5 Destination IPv4 Internet IPv4 GGSN Traffic Steering Mobile Optimization F5 Networks, Inc 18

19 What s Next? We don t just have a problem in our mobile environment but also in our wire line lets tap on this infra. F5 Networks, Inc 19

21 What s the progression? - IPv6 - LTE/4G F5 Networks, Inc 21

22 Mobile and Wireline SP After NAT44 Mobile Smart Devices 3G IPv4(Pri) IPv6(Pub) PC/Laptop HSPA/HSDPA 3G Destination IPv4 Destination IPv4 F5 NAT44 NAT64 F5 Destination IPv4 Destination IPv4 Internet IPv4 GGSN 4G Traffic Steering IPv4(Pri) Mobile Optimization (Flash networks) BRAS Broadband F5 Networks, Inc 22

23 Mobile and Wireline SP After NAT44 Mobile Smart Devices 3G IPv4(Pri) IPv6(Pub) PC/Laptop HSPA/HSDPA 3G GGSN Destination IPv4 Destination IPv4 F5 NAT44 NAT64 F5 DS-Lite Destination IPv4 Destination IPv4 Internet IPv4 4G Traffic Steering IPv6(Pub) IPv4(Pri) Mobile Optimization (Flash networks) BRAS Broadband F5 Networks, Inc 23

24 F5 has migrated the SP network to be IPv6 ready to switch, obsolete or remove IPv4 anytime or when the world is ready for an all IPv6 world. F5 Networks, Inc 24

25 Moving To IPv6 Considerations Enterprise Users Accessing the Application (Intranet, CRM, E-Banking, E-Shop etc) Applications to move to IPv6 Addresses Allow Users to access IPv6 Natively without depending on the Service Providers to handle Translation Should not affect and Transparent to User Existing Condition and Usability 3 Steps Build an IPv6 Network Rewrite/Recode Applications To Be IPv6 Ready Migrate to IPv6 F5 Networks, Inc 25

26 What can you do Enterprise F5 Recommends Dual Stack Gateway Dual Stack Dual Stack Gateway Pros Easiest green field deployment Eventual Environment Pros No impact on legacy systems Seamless any device any app connection Cons Issues with Legacy applications and devices Too much to do at once Cons Need of application awareness Session and NAT density termination stress F5 Networks, Inc 26
