Sivakumar Status: Informational Stream: IETF Date: April 2013 Mailbox: rpenno@juniper.net, tasaxena@cisco.com, mohamed.boucadair@orange.com, ssenthil@cisco.com Pages: 15 Characters: 33171 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-behave-64-analysis-07.txt URL: http://www.rfc-editor.org/rfc/rfc6889.txt Due to specific problems, Network Address Translation - Protocol Translation (NAT-PT) was deprecated by the IETF as a mechanism to perform IPv6-IPv4 translation. Since then, new efforts have been undertaken within IETF to standardize alternative mechanisms to perform IPv6-IPv4 translation. This document analyzes to what extent the new stateful translation mechanisms avoid the problems that caused the IETF to deprecate NAT-PT. This document is a product of the Behavior Engineering for Hindrance Avoidance Working Group of the IETF. INFORMATIONAL: This memo provides information for the Internet community.
