Project Description

      CNDEP (Controller Network Data Extracting Protocol) is asymetric protocol that is used by the Middle-tier Server in three-tier Client/Server architecture to "extract" monitoring data from microcontroller that work in the local network in the rear-end of the architecture. The protocol is byte-oriented and runs over UDP/IP. It is constructed by start delimiter byte, code byte, data bytes (optional) and end delimiter byte. Some types of packets did not need data bytes (e.g. OK packet, Request packet).

      Full description of the protocol can be found in the pdf version.
