Delay-Tolerant Networking Previous-Hop Insertion Block
Abstract
This document defines an extension block for use with the Delay-
Tolerant Networking (DTN) Bundle Protocol. This Previous-Hop
Insertion Block (PHIB) extension block is designed to be inserted by
a forwarding node to provide the endpoint identifier (EID) of an
endpoint of which the forwarding node is a member so that this EID
may be conveyed to the next-hop receiving node. Knowledge of an EID
of an endpoint of which a previous-hop node is a member may be
required in some circumstances to support certain routing protocols
(e.g., flood routing). If this EID cannot be provided by the
convergence layer or other means, the PHIB defines the mechanism
whereby the EID can be provided with the bundle. Each PHIB is always
removed from the bundle by the receiving node so that its presence
within the bundle is limited to exactly one hop. This document
defines the format and processing of this PHIB. This document is a
product of the Delay-Tolerant Networking Research Group and has been
reviewed by that group. No objections to its publication as an RFC
were raised.
Status of This Memo
This document is not an Internet Standards Track specification; it is
published for examination, experimental implementation, and
evaluation.
This document defines an Experimental Protocol for the Internet
community. This document is a product of the Internet Research Task

Task Force (IRTF). Documents approved for publication by the IRSG
are not a candidate for any level of Internet Standard; see Section 2

1. Introduction
This document defines an extension block for use with the Bundle
Protocol [RFC5050] within the context of a Delay-Tolerant Networking
architecture [RFC4838]. The DTN Bundle Protocol defines the bundle
as its protocol data unit and defines "bundle blocks" to carry data
of different types. This document defines an optional bundle block
called a Previous-Hop Insertion Block (PHIB).
The PHIB is inserted into a bundle by a forwarding node to provide
the endpoint identifier (EID) of an endpoint of which the forwarding
node is a member so that this EID may be conveyed to the next-hop
receiving node. (Hereafter, an EID of an endpoint of which a node is
a member will be referred to as an "M-EID" of that node. A node may
have one or more M-EIDs, depending on the number of endpoints to
which it belongs. An EID of a singleton endpoint of which a node is
a member will be referred to as a "singleton M-EID" of that node.)
