3 Three Business Cases for IPv6 Solving for CGN Going Mobile IoE => $14.4 Trillion Value IPv6 World Congress February 2011 IPv6 World Congress March 2012 IPv6 World Congress March % Capex Reduction According to IDC report* for wireline operators deploying IPv6 alongside CGN *Free announces IPv6 to all users by default. (Stockprice up 300% since.) Fix the 15 xlat464 technology allows IPv4 applications to work on IPv6-only networks T-mobile has deployed 4 million IPv6-only phones Connecting the Unconnected 50B+ devices by 2020 IPv6-only architectures for the Internet of Things Source: * Cisco Public 3

IPv6 addresses are, via correlated meta-data or bit-level semantics, a consistent, end to end, identifier throughout the network that allows policy based decisions to occur anywhere needed. 2. IPv6 Addresses are not limited to one per device (each device may have many), and are not manipulated by NATs 3. IPv6 Segment Routing allow for Source routing/ Traffic engineering and Service chaining 4. Legacy IPv4 application can be supported via MAP, xlate464 and NAT64 19
