Some diversity inside Orange Group…

Various situations regarding IPv4 mobile architectures in the

group

– Most of the affiliates assign IPv4 private addresses to UEs (User Equipment) – This pool is limited – Known issues with NAT44

– Performance, service availability, incoming communications, ALG, etc…

– More complex design for accounting & regulatory functions

– Lawful Interception, UE traffic identification

– Some affiliates assign public IPv4 addresses – But public IPv4 address exhaustion is happening – Some affiliates assign both public and private IPv4 addresses

Main hurdles - Devices

Some diversity in terminals portfolio With new chipsets integration more and more devices are IPv6 compliant

considering basic features

More functions are required

– CLAT function for IPv4 service continuity – Prefix delegation capabilities – /64 prefix sharing solution – PCP function – …

Gi Interface Mobile network

• Not exactly an interface but a network
• Currently like some pearl necklace in our architectures
• Various functions are provided: IP translation, Firewalling, DPI, billing,

caching, routing….

• These functions must be « IPv6 compliant » (at least to provide the same

level of service than for IPv4 service)

• New functions (new devices) to be added for IPv4 service continuity

(NAT64 when IPv6-only connectivity is provided)

11 David BINET - Orange 13 juin 2013 Colloque IPv6 – Université de Caen

Hurdles: Roaming

Roaming agreements to be updated for IPv4v6/IPv6 PDP contexts support IPv4 fallback must be ensured if IPv6 connectivity cannot be provided (visited

network does not support IPv6)

– More crucial in IPv6-only scenario

HLR/HSS must be updated to provide IPv4 / IPv6 / IPv4vv6 PDP contexts

– Identification of visited networks in connection request may be required to enable IPv6-only connectivity

White paper for IPv6 transition edited by GSMA Roaming tests not easy to lead (hundreds of roaming situations !) Behavior of some « old » SGSN may not be compliant with new

specifications (none connectivity for IPv6 PDP context)

12 David BINET - Orange 13 juin 2013 Colloque IPv6 – Université de Caen

In a nutshell…IPv6 is here

Core network devices are mature regarding IPv6 features Devices are more and more IPv6 friendly

– More time is required for advanced features

Main applications (Google, Yahoo, Youtube…) are IPv6

compliant

Some Orange affiliates have deployed it and some other

• perators also

Whatever the strategy retained for IPv6 introduction (dual stack

• r IPv6-only), IPv4 and IPv6 protocols will have to be managed

for some time

– Legacy IPv4 devices and applications will be here for some time

13 David BINET - Orange 13 juin 2013 Colloque IPv6 – Université de Caen

Still some efforts to lead..

To avoid any roaming issues To get all required features in devices To be sure middleboxes provide the same level of service than

for IPv4

To consider IPv6 and IPv4 for new architectures

– FMC (Fixed Mobile Convergence), Wi-Fi offload..

But it is also the case for IPv4 !
