Fujii, Y. Zhang Status: Standards Track Date: March 2001 Mailbox: Emmanuel.Duros@UDcast.com, Walid.Dabbous@inria.fr, firstname.lastname@example.org, email@example.com, firstname.lastname@example.org Pages: 25 Characters: 52410 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-udlr-lltunnel-06.txt URL: ftp://ftp.rfc-editor.org/in-notes/rfc3077.txt This document describes a mechanism to emulate full bidirectional connectivity between all nodes that are directly connected by a unidirectional link. The "receiver" uses a link-layer tunneling mechanism to forward datagrams to "feeds" over a separate bidirectional IP (Internet Protocol) network. As it is implemented at the link-layer, protocols in addition to IP may also be supported by this mechanism. This document is a product of the UniDirectional Link Routing Working Group of the IETF. This document specifies an Internet standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "Internet Official Protocol Standards" (STD 1) for the standardization state and status of this protocol. Distribution of this memo is unlimited.
