Gateway-Initiated Dual-Stack Lite Deployment
RFC 6674, “Gateway-Initiated Dual-Stack Lite Deployment”, is a Proposed Standard document published in July 2012 by F. Brockners, S. Gundavelli, S. Speicher, D. Ward. The canonical text is published by the RFC Editor.
Abstract
Gateway-Initiated Dual-Stack Lite (GI-DS-Lite) is a variant of Dual- Stack Lite (DS-Lite) applicable to certain tunnel-based access architectures. GI-DS-Lite extends existing access tunnels beyond the access gateway to an IPv4-IPv4 NAT using softwires with an embedded Context Identifier that uniquely identifies the end-system to which the tunneled packets belong. The access gateway determines which portion of the traffic requires NAT using local policies and sends/ receives this portion to/from this softwire. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
