Abstract

PACnet is a 200-500 Mbps dual-ring fiber optic network designed to implement a Picture Archiving and Communication System (PACS), in a hospital environment. The network consists of three channels: an image transfer channel, a command and control channel and a real-time data channel. An initial network interface unit (NIU) design for PACnet consisted of a functional description of the protocols and NIU major components. In order to develop a demonstration prototype, additional definition of protocol algorithms of each channel is necessary. Using the International Organization for standards/Open Systems Interconnection (ISO/OSI) reference model as a guide, we extend the definition of the data link layer. This definition covers interface service specifications for the two constitutent sublayers: logical link control (LLC) and medium access control (MAC). Furthermore, it describes procedures for data transfer, mechanisms of error detection and fault recovery.
