Abstract

In this paper, we propose a "flexible"switch architecture that can be the basis of high-performance packet switches for B-ISDN nodes, LANs, and PBXs. This switch is being implemented for our Multimedia Integrated Network for Telecommunications (MINT) project, which will support voice, video and data traffic. The switch fabric supports multiple priorities, has a programmable service policy, and has several field-selectable options to match system requirements. In addition, the number of cell buffers and the number of input/output ports all can be easily increased when needed. However, the architecture is most appropriate for small (e.g., up to 32X32) broadband packet (ATM) switches, because the internal switch fabric is fully-connected. The switch uses "output queueing"to achieve the best possible delay-throughput performance. Cells are stored in RAMs, rather than FIFOs, thereby exploiting the memory density of RAM chips and permitting cells of different priorities to use the same chip. The switch allows RAM-based buffer sharing, and judiciously wastes some of the memory to simplify the switch's control circuitry. Also, it supports link-level flow control, if desired.
