CN8236
ATM ServiceSAR Plus with xBR Traffic Management
The CN8236 Service Segmentation and Reassembly Controller integrates ATM terminal
functions, PCI Bus Master and Slave controllers, and a UTOPIA level 1 or 2 interface
with service-specific functions in a single package for AAL0, 3/4, and 5 operations.
The ServiceSAR Controller generates and terminates ATM traffic and automatically
schedules cells for transmission. The CN8236 is targeted at 155 Mbps throughput
systems where the number of VCCs is relatively large, or the performance of the overall
system is critical. Examples of such networking equipment include Routers, Ethernet
switches, ATM Edge switches, or Frame Relay switches.
Service-Specific Performance Accelerators
The CN8236 incorporates numerous service-specific features designed to accelerate
and enhance system performance. As examples, the CN8236 implements Echo
Suppression of LAN traffic via LECID filtering, and supports Frame Relay DE to CLP
interworking.
Advanced xBR Traffic Management
The xBR Traffic Manager in the CN8236 supports multiple ATM service categories. This
includes CBR, VBR (both single and dual leaky bucket), UBR, GFR (Guaranteed Frame
Rate), and ABR. The CN8236 manages each VCC independently. It dynamically
schedules segmentation traffic to comply with up to 16+CBR user-configured
scheduling priorities for the various traffic classes. Scheduling is controlled by a
Schedule table configured by the user and based on a user-specified time reference.
ABR channels are managed in hardware according to user-programmable ABR
templates. These templates tune the performance of the CN8236’s ABR algorithms to a
specific system’s or network’s requirements.
