Abstract

This document defines an extension block for use with the Delay-Tolerant Networking (DTN) Bundle Protocol. This Previous-HopInsertion Block (PHIB) extension block is designed to be inserted bya forwarding node to provide the endpoint identifier (EID) of anendpoint of which the forwarding node is a member so that this EIDmay be conveyed to the next-hop receiving node. Knowledge of an EIDof an endpoint of which a previous-hop node is a member may berequired in some circumstances to support certain routing protocols(e.g., flood routing). If this EID cannot be provided by theconvergence layer or other means, the PHIB defines the mechanismwhereby the EID can be provided with the bundle. Each PHIB is alwaysremoved from the bundle by the receiving node so that its presencewithin the bundle is limited to exactly one hop. This documentdefines the format and processing of this PHIB. This document is aproduct of the Delay-Tolerant Networking Research Group and has beenreviewed by that group. No objections to its publication as an RFCwere raised. This document defines an Experimental Protocol for the Internet community.
