We first talked about the Mapping of Address and Port (MAP) method to handle IPv4 exhaust and the transition to IPv6 last week. MAP is based on two IETF drafts currently in the process of standardization indraft-ietf-softwire-map(MAP-E) anddraft-ietf-softwire-map-t(MAP-T). The real advantage with MAP is that it's stateless and doesn't require additional hardware as traffic grows.  MAP is best as a solution for broadband providers, enabling them to deploy an IPv6 infrastructure targeting the most popular content providers such as Google and Facebook which both make their content available on IPv6. With MAP, service providers can still gracefully support the now diminishing IPv4 traffic while building a strong networking foundation for IPv6.

Hear Cisco Fellow Mark Townsley share his thoughts on the benefits of MAP and why it's the right solution for many network operators.
