    Performance Evaluation of BACnet MS/TP Protocol Using Experimental Model

    No full text
    Digital communication networks have become a core technology in advanced building automation systems. BACnet(Building Automation and Control networks) is a standard data communication protocol designed specifically for building automation and control systems. BACnet adopts Master-Slave/Token-Passing (MS/TP) protocol as one of its field level networks. In this study, we evaluate the performance of BACnet MS/TP protocol using experimental model. The network performance is investigated and evaluated in terms of token rotation time and service delay. Experimental results show that the performance of MS/TP network is heavily affected by the network configuration parameter called N max_info_frames.This study was supported by grant No. R01-2002-000-00046-0 from the Basic Research Program of the Korea Science & Engineering Foundation

    A Simulation Model for Time-sensitive Networking (TSN) with Experimental Validation

    Industrial communication requires highly reliable networks with hard temporal constraints. Thus, the IEEE 802.1 Task Group proposed a promising technology, namely, time-sensitive networking (TSN), to complement the determinism and real-time (RT) capabilities of Ethernet via a set of enhanced IEEE standards. To explore the feasibility and applicability of TSN, we developed a simulation model for TSN using a module-based design method. Our TSN-compliant modules implement time-based traffic scheduling functionality to guarantee the deterministic and RT transmission of time-triggered traffic. We validated the developed modules by comparing the end-to-end simulation latencies to those measured in a real-world TSN testbed. The results of this evaluation validate the proposed simulation model and show that it conforms tightly to the TSN specifications and faithfully matches the real-world testbed.This work was supported under three foundations, two of which are the international cooperation program (Korea-China) managed by the National Research Foundation of Korea (NRF-2016K2A9A2A11938310 and NRF-2018K1A3A1A61026320), the other is National Key R&D Program of China (2017YFE0123000)
