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.
