Quad 32 Class traffic shaperTo profile ATM cell streams on 4 UTOPIA compliant ATM ports
originating fromunpredictable sources (like LANs) or after
cumulation of bursts into welldefined ATM traffic contracts
the components enables the distribution of inputtraffic into 32
independent queues (configurable from 2 to 2M cell storage).
The queues are grouped into 12 groups. 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 multi port
unidirectional UTOPIA compliant link. Main application is the
on-the-flyprofiling of cell streams into multiple physical links
at the output of anetwork node. Service subclasses per port are
achieved by the queue subgroupingfeature. Arbitrary output
characteristics including ABR typical ones can be setup.
- Multiple port UTOPIA-1 compliant ATM interface 155 Mb/s
- 32 queues each capable of storing 2-2M cells
- Queue grouping into 12 groups
- 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
