The Reliable Data Protocol (RDP) is designed to provide a
reliable data transport service for packet-based applications
such as remote loading and debugging. The protocol is intended
to be simple to implement but still be efficient in environments
where there may be long transmission delays and loss or non-
sequential delivery of message segments.

Although this protocol was designed with applications such
as remote loading and debugging in mind, it may be suitable for
other applications that require reliable message services, such
as computer mail, file transfer, transaction processing, etc.
