Constrained Application Protocol (CoAP) over Bundle Protocol (BP)
The Bundle Protocol (BP) was designed to enable end-to-end
communication in challenged networks. The Constrained Application
Protocol (CoAP), which was designed for constrained-node networks,
may be a suitable application-layer protocol for the scenarios where
BP is used. This document specifies how CoAP is carried over BP.
