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 David BINET - Orange 13 juin 2013 Colloque IPv6 – Université de Caen 3

Hurdles: (s)Gi interface impacts IPv4/IPv6 IPv4/IPv6 IPv4/IPv6 IPv4/IPv6 Applications Applications Applications Applications Mobile network GGSN/P- GGSN/P GGSN/P GGSN/P - -GW - GW GW GW Gi Interface - 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) David BINET - Orange 13 juin 2013 Colloque IPv6 – Université de Caen 10
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) David BINET - Orange 13 juin 2013 Colloque IPv6 – Université de Caen 11
