ATM SAR and Traffic Manager Processor:
APP550TM and APP530TM
Introduction
Agere Systems is extending its technological
leadership with the next generation of ATM SAR and
Traffic Manager devices, the APP550TM and the
APP530TM. The APP550TM and APP530TM are
standalone processors that provide AAL5 SAR and
Traffic Management functions for edge/access and
multiservice applications. These chips provide:

Description
ATM and IP interworking is enabled through the
embedded AAL5 segmentation and reassembly
(SAR) functionality in the APP550TM and
APP530TM.
Both chips provide integrated policing/metering and
statistics functions (128k virtual channel/flows) to
enable flexible billing and accounting metrics for
both ATM cells and IP/Ethernet packets. Buffer
management across 256k queues, hierarchical
scheduling, and shaping functions for both cell and
packet are also integrated into both chips.
2.5 Gbits/sec ATM AAL5 SAR
Control of data flow across the network
Service-Level Agreement (SLA) enforcement
Traffic management
Optimization of network resources
Provision of bandwidth delay and jitter guarantee
for PDUs to transverse the network
Complete ATM and IP interworking
System Overview
Both the APP550TM and the APP530TM are based
on the Agere Systems PayloadPlus
proven platform provides a complete hardware and
software solution for building multiservice
applications. In addition to to all of the PayloadPlus
features, the APP550TM and APP530TM provide:

The APP550TM operates at a line speed of 5Gbits/s
and is well suited for both multiservice applications
and edge/access applications. The APP530TM
provides the same features as the APP550TM, at a
line speed of 2.5Gbits/s. The APP530TM is
designed for multiservice applications.
Features and Benefits
Agere System’s devices provide significant features
and benefits as you build multiservice applications.
These include:
I
Segmentation and reassembly
Cell and packet policing/metering
Statistics
Advanced buffer management
Strict ATM scheduling (including virtual channel
[VC] and virtual path shaping)
VC merge functions
Complete I.610 Operations, Administration, and
Maintenance (OAM) functionality
Wire-Rate Bidirectional AAL5 SAR (APP550)
AAL5 SAR capabilities are embedded in the
APP550TM and APP530TM. This enables the
flexible hardware engines to achieve bidirectional
line rates without sacrificing protocol interworking
flexibility.
