Implementation of label switching for distributed control in instrumentation system

This article describes an implementation of label switching technique in data acquisition and control design for instrumentation control system. Multi-protocol Label switching (MPLS) and Basic Stamp II (BS-2) module are utilised in this system. Two layers of data labelling are defined for the system by considering the average distance and area of the system. This study has found that label switching concept that is being used for instrument unit data communication has the potential to be re-configured with the increment of number of instrumentation system and devices. Apart from that, limitation of processing unit memory and data storage could also affect the performance of data forwarding. However, these limitations has minimum effect on deploying scaling forwarding via label switching technique for instrumentation communication and control purposes.
