About the talk:
Network address translation (NAT) has become an important technology in the Internet, supporting address reuse, addressing autonomy, transparent redirect, endpoint concealment and other uses. However, NAT has a number of deficiencies, like breaking the original Internet architecture and conflicting with end-to-end reliability and security. TRIAD is a proposed architecture that solves these problems with NAT. It bases identification on DNS names, restoring end-to-end semantics by using a name-based pseudo-header, and extending the inter-realm addressing with a "shim" protocol on top of IPv4. We claim that TRIAD is scalable and incrementally deployable in the current Internet. It also raises the question of whether we really need to go through the challenging transition to IPv6 in order to scale the Internet. This talk describes TRIAD and our implementation/results to date.
