A new Request for Comments is now available in online RFC libraries. RFC 6971 Title: Depth-First Forwarding (DFF) in Unreliable Networks Author: U. Herberg, Ed., A. Cardenas, T. Iwao, M. Dow, S. Cespedes Status: Experimental Stream: IETF Date: June 2013 Mailbox: ulrich.herberg@us.fujitsu.com, alvaro.cardenas@me.com, smartnetpro-iwao_std@ml.css.fujitsu.com, m.dow@freescale.com, scespedes@icesi.edu.co Pages: 41 Characters: 95276 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-cardenas-dff-14.txt URL: http://www.rfc-editor.org/rfc/rfc6971.txt This document specifies the Depth-First Forwarding (DFF) protocol for IPv6 networks, a data-forwarding mechanism that can increase reliability of data delivery in networks with dynamic topology and/or lossy links. The protocol operates entirely on the forwarding plane but may interact with the routing plane. DFF forwards data packets using a mechanism similar to a "depth-first search" for the destination of a packet. The routing plane may be informed of failures to deliver a packet or loops. This document specifies the DFF mechanism both for IPv6 networks (as specified in RFC 2460) and for "mesh-under" Low-Power Wireless Personal Area Networks (LoWPANs), as specified in RFC 4944. The design of DFF assumes that the underlying link layer provides means to detect if a packet has been successfully delivered to the Next Hop or not. It is applicable for networks with little traffic and is used for unicast transmissions only. EXPERIMENTAL: This memo defines an Experimental Protocol for the Internet community. It does not specify an Internet standard of any kind. Discussion and suggestions for improvement are requested. Distribution of this memo is unlimited.
