An emerging concept in picture archiving and communication systems (PACS) is the PACS infrastructure. The critical components in this infrastructure are communication systems, cluster controller, database integration, fault-tolerant design, and systems integration software. The architecture of a comprehensive communication system within this infrastructure, which will support a digital-based radiology operation, is described. This communication network consists of a real-time analog video and digital components. The video network utilizes broadband and fiber-optic communication technologies. The digital communication is based on a three-tiered network integrating Ethernet, FDDI, and Ultranet technologies. The digital network uses the standard TCP/IP protocol and has a fault-tolerant design. Both components have been in clinical operation since the summer of 1991
