Internet-Draft Bundle-in-Bundle Encapsulation February 2020
Abstract
This document describes Bundle-in-Bundle Encapsulation (BIBE), a
Delay-Tolerant Networking (DTN) Bundle Protocol (BP) "convergence
layer" protocol that tunnels BP "bundles" through encapsulating
bundles. The services provided by the BIBE convergence-layer
protocol adapter encapsulate an outbound BP "bundle" in a BIBE
convergence-layer protocol data unit for transmission as the payload
of a bundle. Security measures applied to the encapsulating bundle
may augment those applied to the encapsulated bundle. The protocol
includes a mechanism for recovery from loss of an encapsulating
bundle, called "custody transfer". This mechanism is adapted from
the custody transfer procedures described in the experimental Bundle
Protocol specification developed by the Delay-Tolerant Networking
Research Group of the Internet Research Task Force and documented in
RFC 5050.
