System Architectures Using Network-Attached Peripherals Rodney Van Meter USC/ISI Peripherals such as displays, cameras, disk drives and tape drives are typically attached directly to the system bus of a computer. However, a number of recent research projects, including ISI's Netstation, have investigated the arhictectural implications of attaching the peripherals directly to a network rather than a bus. These peripherals are called network-attached peripherals (NAPs), or more specifically, network-attached storage devices (NASDs). In this seminar we will explore the space of architectures involving such devices. The important issues of operating system support for NAPs, network protocols, network technologies, security and appropriate programming paradigms will be presented. Rod Van Meter has been institutionalized almost continuously since the age of sixteen, first at the California Institute of Technology, then at USC's Information Sciences Institute. At ISI he held positions in the Information Processing Center and the MOSIS project from 1986 until 1992, when he escaped to Japan to do SCSI interfaces for mass storage peripherals. In April of 1995 he was recaptured by ISI, where he is currently a computer scientist working on the Netstation project in the computer networks division.
