Advanced PayloadPlus APP540 and APP520

Packet-Optimized Network Processors

Introduction

The Agere Systems Advanced PayloadPlus

APP540 and APP520 Network Processor devices

are the latest addition to the PayloadPlus family of

products. They offer a comprehensive

programmable solution with 5Gbps of classification,

network processing, and traffic management

throughput in a single highly integrated chip. The

APP540/520 integrate the functions of a network

processor, traffic manager, search engine, and

Ethernet MAC device to enable network system

architects to build very high density, high

performance multiprotocol packet processing

systems. The devices are designed for high

performance packet processing applications

including Ethernet over SONET/SDH switches,

packet edge routers, Cable Modem Termination

Systems, IP DSLAMs, and layer 2/3/4 switches.

The PayloadPlus product family represents a

technological revolution for intelligent

communication equipment with Layer 2 and above

processing capabilities. Agere Systems products

focus on the wire-speed datapath functions and

work in conjunction with physical interface devices, a

low-speed microprocessor, and backplane fabric

offerings for networking and communication

applications.

Description

The APP540 and APP520 are complete,

programmable, single-chip network processors with

integrated classification and traffic management

capabilities. Both devices are software-compatible

with the other members of the PayloadPlus family of

network processors from Agere Systems.

The APP520 has 2GbE MACs integrated and

supports programmable policing and statistics using

on-chip memory. The APP540 has 4GbE MACs

integrated and supports the use of external memory

to store policing and statistics state information.

Both devices also integrate 16 10/100 Ethernet

MACs and support up to 5 Gb/s total processing

throughput.

The APP540/520 accepts a data stream composed

of either frames or cells/blocks from an industry-

standard interface, analyzes and classifies the

frames or cells/blocks, reassembles them into

PDUs, classifies the resulting PDUs, updates

policing, statistics, and other state information, and

then performs buffer management, traffic

scheduling/shaping, and data modification before it

transmits the PDUs.

The APP540/520 supports the following interfaces:

The APP540/520 supports robust multiprotocol

packet processing capabilities, including support for:

Media — supports the following standards:

—POS-PHY Level 3

—GMII (4/2 integrated GbE MACs)

—SMII (16 integrated 10/100 MACs)

Fabric — a second POS-PHY Level 3 interface

that can be directed to a switch fabric or

coprocessor for additional function support.

PCI interface — a 32-bit/66 MHz Peripheral

Component Interconnect (PCI) bus enables

custom logic that is used to configure the

APP540/520 and other system devices.

Rigorous bandwidth, delay, and jitter

guarantees to support high-value service level

agreements and enable frame relay-like service

over Ethernet

Hierarchical scheduling and shaping to provide

QoS guarantees to groups of related traffic
