Sharing the dream

We reconsider desirability of the bundle protocol (BP) as a universal solution for delay- and disruption-tolerant networking (DTN). The BP is intended to provide a single solution that is applicable to a wide variety of differently-challenged DTN networks, even though those networks are unlikely to interact with one another. This paper asks whether such a single protocol can encompass all varied DTN networking needs. It asks whether attempting to repeat the previous success of the homogeneous Internet by layering over all networks is suitable for the heterogeneous DTN world, where diverse application needs and operational requirements lead to diverse, scenario-specific, applications. This position paper is intended to encourage discussion of the role, scope, and adoption of the BP.
