Controls for the Spallation Neutron Source (SNS) will be implemented using an EPICS-based distributed control system. The SNS controls communication network will take advantage of new, commercially available network switch features to increase reliability and reduce cost. A standard structured cable system will be installed. The decreasing cost of network switches will enable SNS to push the edge switches out near the networked devices and to run high-speed fiber backbone communications all the way to the edge switches. Virtual Local Area Network (VLAN) technology will be used to group network devices into logical subnets while minimizing the number of switches required. Commercially available single-board computers with TCP/IP interfaces will be used to provide terminal service and remote power reboot of EPICS I/O controllers.
