The Physical Internet (PI) is an innovative system that aims to revolutionize current paradigms of global logistics. It is founded on the designing principles of the Digital Internet, such as transparency, resource sharing, and information exchange, with the goal of creating a more efficient and environmentally friendly logistics network. Unlike the Digital Internet, where network packets contain routing information within them, the PI operates differently. It requires a network of communication protocols to support global interconnection and collaboration to ensure effective delivery to the destination. In this regard, the present thesis work has clarified the types of information and data exchanged in various logistical processes within the Physical Internet.
