EPICS and WANs: Tradeoffs between Isolation, Security, Robustness, and Transparency
The Experimental Physics and Industrial Control System (EPICS)[1] was originally designed for use in local area networks (LANs). Today, the system is routinely deployed into complex wide area networks (WANs) using specialized configuration options and proxy gateways. There are advantages to the current approach including robustness and control over isolation and security. However, some important features are missing including WAN transparent configuration, resource location monitoring, detection of name space collisions during installation, and wildcard queries into the resource attribute space. The paper discusses these issues in detail exploring the relative tradeoffs between different solutions and including our plans for future enhancements.
