ANSI/ISA-TR100.15.01-2012, Backhaul Architecture Model: Secured Connectivity over Untrusted or Trusted Networks, presents a comprehensive architecture model for securely connecting industrial control system elements over both trusted and untrusted backhaul networks. It focuses on wireless technologies but is applicable to wired networks as well. It offers a standardized framework that facilitates interoperability among diverse vendors, protocols and backhaul providers while addressing critical aspects such as security, management, fault tolerance, mobility and flow control. By providing clear definitions, interface models and security overlays aligned with established standards like ISA/IEC 62443, this technical report supports the design and deployment of robust, scalable and flexible backhaul solutions capable of handling mixed-use scenarios including industrial data, voice, video and mobile worker connectivity. This approach helps organizations manage complex network environments more effectively, adapt to evolving technologies and maintain operational continuity in demanding automation settings.
