    ATM Self Routing Switch Element

    The SRE is a 4x4 cell-switch building-block, which can be used as the basis for a variety of 155Mbps ATM switch fabrics. Although various interconnection topologies can be used, the SRE is ideally suited to the construction of compact matrices due to its row and column expansion ports. These provide re-timed, buffered outputs to simplify device interconnection. Other key features are:

    • Support for FECN/BECN congestion control based on internal queue fill-levels
    • Selectable high and low priority queues
    • Output queued for non-blocking operation
    • Multicast support
    • Selective cell discard based on CLP bit and selectable queue fill-levels
    • Statistics gathering for cell discards and buffer overflows
    • Routing tag processing is programmable to enable flexibility of switch architecture
    • JTAG compliant

    Technology: CMOS
    Package: PQFP 176 Pin
