Frame Relay
ATM Traffic
Comprehensive traffic management.
The ASPEN Express delivers all the functionality necessary to
implement high-density ATM applications including cell address
translation, cell routing and outlet cell queuing. The extensive traffic
management capabilities of the ASPEN Express guarantee that
allocated bandwidth and QoS requirements are completely satisfied.
Eight service classes are accommodated by the ASPEN Express:
CBR, VBR-rt, VBR-nrt, GFR, ABR, and three user defined classes,
which can be used to support differential services with multiple
levels of UBR priority. This allows for minimal delay of critical data
service types. The ASPEN Express’ outstanding traffic management
features are executed through Early Packet Discard (EPD) and Partial
Packet Discard (PPD), policing per TM4.1, and OAM Fault
Management per ITU-T I.610. Ingress queuing enhances the ability to
fully utilize the CellBus bandwidth so that during congestion, low
priority traffic can be queued on the inlet side until high priority
traffic has been de-queued. ASPEN Express also implements a
backpressure mechanism that prevents cell loss from egress
queue congestion - thus enhancing your system’s overall quality
and efficiency.
