32 Class traffic shaperTo 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.
