Bundle Protocol

Bundle protocol is an experimental disruption-tolerant networking (DTN) protocol designed for unstable communications networks. It groups data blocks into bundles and transmits them using a store-and-forward technique.

Bundle protocols connect multiple subnets into a single network. They provide a custody-based retransmission service and store data for long periods. The signal retransmitter guarantees packet delivery. As such, they can easily cope with Internet connectivity issues such as bandwidth delays and breakups.

Bundle protocol is specified as RFC5050.
