TCP/IP-based Network Configuration for Cyber-Physical Internet

Cyber-Physical Internet (CPI) is a transformative global logistics paradigm that aims to replicate the efficiency and interconnectivity of the digital internet for the physical movement of goods. However, traditional logistics systems suffer from inefficient data handling, non-standardized addressing, and unreliable communication in multi-tier environments. This paper highlights an advanced IP-centric framework for CPI. The framework integrates a hierarchical IPv6-based addressing scheme, a memory-efficient Left-Child Right-Sibling (LCRS) algorithm, and a reliable Read-and-Reply communication mechanism. The proposed addressing scheme utilizes a Wide Area Network (WAN), Catchment Area Network (CAN), and Local Area Network (LAN) hierarchy to provide scalable, globally unique identification for logistics nodes and Protocol Shipment Units (PSUs). To support resource-constrained IoT devices, the LCRS algorithm is introduced to restructure the routing table, achieving a 53.85% reduction in memory footprint. This optimization enables the routing table to fit entirely within the on-chip SRAM of edge devices, effectively overcoming the memory wall challenge. Furthermore, the Read-and-Reply mechanism— inspired by the TCP three-way handshake—ensures reliable task coordination and goods transfer, maintaining a 97.25% communication reliability rate even under a 20% packet loss rate. Experimental results demonstrate that this framework significantly reduces routing table overhead and enhances communication reliability compared to traditional flat addressing and push-based protocols.
