A reliable communication protocol RUDP is provided to transfer data between two systems connected in a network. Working over the unreliable UDP transport layer protocol, the RUDP protocol adds an acknowledging mechanism to otherwise unreliable UDP packets. Contrary to the TCP transport layer protocol, which establishes a connection before any data transfer, the RUDP is used to transfer short amounts of information or messages, so a connectionless communication is used. In a connectionless context the complexity of the encoding-decoding algorithm and the amount of memory consumed by the protocol is reduced. Such characteristics makes the RUDP protocol suitable for its implementation in systems with limited memory and speed, like low processing power 8-bit microcontrollers. Furthermore, by programming the RUDP protocol over the UDP protocol, its implementation in a personal computer can be made with common programming tools.
