ABSTRACT
Although custodial transmission of multicast bundles
would be a desirable capability to have in Delay-Tolerant
Networks (DTNs), support for custodial multicast transmission
was omitted from the Bundle Protocol Specification because of its
complexity. This paper explains the difficulties that arise with
respect to supporting custody transfer and retransmission of
multicast bundles, and it describes some potential solutions for
addressing these issues that the authors are currently exploring
as work-in-progress.
