NI Simple Messaging (STM) Reference Library - National Instruments LabVIEW API for Network Communication in Distributed Systems

  • Easily packages and parses data
  • Hides the transport layer (TCP/IP, UDP, and so on) implementation details
  • Minimizes network traffic by sending data only when it is needed
  • Lends itself to communication with environments other than NI LabVIEW (C, C++, and so on)

One of the main challenges for engineers who design distributed systems where hosts interact using a network is building an effective communication protocol. The NI Simple Messaging (STM) Reference Library can enhance the performance, usability, maintainability, and scalability of a distributed system. Unlike raw communications APIs, using formatted packets makes data manipulation more manageable and improves throughput by minimizing the transmission of repetitive data.
