TelscomWhy do we need IPv6 6 IPv6 Features IPv6 has been recognised as the future protocol by IETF, Eurescom, and 3GPP and vendors –Uses 128 bit address space and Hierarchical addressing Improved routing based on aggregated addresses –Autoconfiguration Computers assign themselves an Ipv6 address –IP Mobility End devices can roam onto other networks –Improved security Authentication and encryption at the packet level –Better support for QoS Integrated QoS, multicasting

TelscomWhy do we need IPv6 8 NGN Requirements - IPv6 Requirements –Scalability of networks with address space,QoS and security, which are basic features of IPv6 networks –Connectivity with existing IPv4 networks is necessary –IPv6 should happen from the edges, not from the core. –Applications are important for pushing IPv6 it has to be transparent to the end user –Interoperability with IPv4 has a cost 100% interoperability is not always necessary –We need a credible transition story.
