Included in the ION software distribution are the following packages: * ici (interplanetary communication infrastructure) a set of libraries that provide flight-software-compatible support for functions on which the other packages rely * bp (bundle protocol), an implementation of the Delay-Tolerant Networking (DTN) architecture's Bundle Protocol. * dgr (datagram retransmission), a UDP reliability system that implements congestion control and is designed for relatively high performance. * ltp (licklider transmission protocol), a DTN convergence layer for reliable transmission over links characterized by long or highly variable delay. * ams - an implementation of the CCSDS Asynchronous Message Service. * cfdp - a class-1 (Unacknowledged) implementation of the CCSDS File Delivery Protocol.
