Requires:
� Physical layer characterization
� Ethernet & IPv4 and v6 interop & performance testing/troubleshooting
�Signaling Testing & Troubleshooting
�Application layer End to end QoE Testing & Monitoring

IPv6 Testing & Troubleshooting Challenges
� Benefits: efficient routing & packet handling , Security (IPSec), Mobility, Addressing,
Administration (built in plugnplay), NAT elimination, multicast support
� IPv6 is seen as an enabler for new always on applications & services, i.e., P2P, M2M,
� Both IPv4 and IPv6 will co-exist for number of years
Challenges:
� Impact on the control and the data Plane with dual stack support (IPv4 and IPv6)
� Tunneling IPv6 over IPv4 and address translation
� Requires – tools to test/troubleshoot
� Performance (Data and Control plane); Generate monitor and analyze IPv6 traffic
� Tunneling (v6 over v4, GRE, ISATAP, MPLS); IPv6 payload over Ethernet, v6 over PPP etc.
