    Atecom (ATecoM GmbH ) : ATM-SHAP3

    32 Class traffic shaper

    To profile ATM cell streams originating from unpredictable sources (like LANs)or after cumulation of bursts into well defined ATM traffic contracts the components enables the distribution of input traffic into 32 independent queues(configurable from 2 to 2M cell storage). The distribution is based on VPI/VCI. The queues output behavior is controlled by Double Leaky Bucket which already allows for a 3-step tuning of the output characteristic. In addition 32 independent parameter sets per queue are available. Selection of the active setis either via hardware or software. The component supports singleunidirectional UTOPIA compatible link. Main application is the on-the-flyprofiling of cell streams into physical links at the output of a network node. Arbitrary output characteristics including ABR typical ones can be set up.

    • Single link UTOPIA-1 compliant ATM interface 155 Mb/s
    • 32 queues each capable of storing 2-2M cells
    • Internal single or dual leaky bucket, shaping function
    • 32 Shaping parameter sets per bucket select-able per hardware for flow control
    • Minimum output rate 9 Kb/s, Burstiness 0 - 64K cells
    • Flow control feature (output can be stopped while input still receives cells)
    • Static, round-robin priorities and mixture of both
    • Counting of lost cells

    Technology: unknown
    Package: PQFP 160 Pin
