Introduction

The growth of the Internet brings constant

challenges to vendors who supply data

networking infrastructure equipment, and to

manufacturers, who are expected to provide

increasingly higher performance, lower cost

products more quickly than ever. Vendors have

struggled to pull solutions together from disparate,

even incompatible, sources—a real-time

operating system from one supplier , management

software from another, and protocol stacks and

drivers from still other sources. In addition, wire-

speed IC components often lacked the

programmability to address new network

protocols at the speeds required to meet network

bandwidth growth. What was needed was a fully

integrated system that could provide both

solutions—scalability and programmability.

The combination of WindRiver's Tornado for

Managed Switches (TMS) and Agere Systems’

PayloadPlus network processors is that system.

WindRiver Tornado for Managed

Switches

Tornado for Managed Switches 2.0 is the an

integrated software solution for the control and

management of any Layer 2 or Layer 3 switching

device. TMS integrates with a variety of hardware

platforms to offer out-of-the-box solutions for a

broad range of devices, from enterprise Ethernet

switches to gigabit MAN switches/routers.

Agere Systems PayloadPlus OC-48c

Network Processor

The Agere Systems PayloadPlus chip set is a

breakthrough OC-48c network processor solution

that performs all the classification, policing, traffic

management, QoS/CoS, traffic shaping, and

pack e t mo di f ic at i on f u nc ti o ns ne e de d for a carrie r

class network platform. The PayloadPlus product

family represents a technology revolution in the

construction of intelligent communication

equipment with multiprotocol processing

capabilities.

The PayloadPlus family includes the Fast Pattern

Processor (FPP), Routing Switch Processor

(RSP), and the Agere System Interface (ASI). The

FPP and RSP process the wire-speed data

stream. The ASI provides an industry-standard

Peripheral Component Interconnect (PCI)

interface betwe en a control processor and

Agere's high-speed FPP and RSP for control and

management functions, including routing table

and virtual circuit updates, hardware

configuration, and exception handling. The ASI

assists the FPP in policing ATM and Frame Relay

traffic at up to OC-48c rates, maintaining state

information on data flows, and capturing statistics.

Agere has also announced the Voice Packet

Processor (VPP), a coprocessor capable of AAL2

SAR and switching functions for up to 32,000

conversations on ATM networks.

Network Processing Architecture Provides

Networking and Scalability

Agere's functional processor design combines the

flexibility and programmability of the traditional

RISC processor with the performance of an ASIC.

Agere's PayloadPlus architecture supports

bandwidth speeds of OC-192 and beyond and is

directly scalable to higher levels of integration and

speeds beyond 2.5 Gbits/s, including 10 Gbits/s

and 40 Gbits/ s. A paten ted tec hno logy called

Pattern Matching Optimization achieves greater

than 5x performance improvement over other

network processors. The PayloadPlus architecture realizes

these performance gains by using less overhead, fewer

clock cycles, and more data processing per clock cycle than

an augmented RISC processor.

This combin ation will allow network OEMs to offer an

integrated system consisting of WindRiver's industry-

leading TMS software and Agere's network processors.

Software developed on this OC-48c platform will have a

clean migration path to OC-192 platforms and beyond.

Control Path and Data Path Processing

The following diagram shows how the PayloadPlus design

addresses OC-48c data path functions. Data path

processing involves wire speed processing of specified

functions. Slower, control path processing is handled by

the ASI and a microprocessor. It is the network processors,

then, that determine the speed, level of programmability,

and supported features in a system. The microprocessor

and software enable the adherent network protocols,

management, and system con fig ur ation of the syst em .

Combining TMS and PayloadPlus

Combining the breakthrough performance of Agere's

network processors and WindRiver's TMS software offers

Network OEMs a new level of integrated performance,

scalability, programmability and routing/switching services.

The initial TMS offering on Agere Systems’ Integrated

Development System (IDS) enables TMS-based IP

services and protocols with the TMS protocol stack using

the PayloadPlus processor chip set. A new Switch Support

Package (SSP) will be developed to integrate the Agere

Systems chip set into the TMS architecture.

TMS Overview

Complete, Embedded Software Solution

WindRiver’s TMS provides a complete embedded software

solution for data networking switch and router equipment.

TMS, when combined with off-the-shelf network processors

or switch fabric devices, enables manufacturers to quickly

build leading-edge Internet infrastructure equipment. TMS

can easily be extended to address a wide range of network

applications that includes Ethernet switches and routers,

virtual private network (VPN) servers, firewalls, and

broadband access concentrators.

Tornado is the most widely used integrated environment for

embedded systems development. TMS combines the

powerful Tornado development enviro nment with the most

complete set of Layer 2 and Layer 3 networking

applications and protocols. Developing a world-class switch

or router has nev er been easie r.

Tailored Networking Packages

TMS extends the Tornado platform with software packages

targeted to either Layer 2 switches or Layer 3 IP routers.

Basic Layer 2 Switch Package

TMS is the industry´s most complete package of Layer 2

switch components. Layer 2 functions are required in

Ethernet switches and in next generation MAN and WAN

switches that use Gigabit and 10 Gigabit Ethernet. Many

next-generation applications will use such Layer 2 functions

as VLAN and 802.1P priority queueing to offer value-added

services such as virtual private networks to MAN and WAN

users.

Note: Version 1.0 TMS had two Layer 2 options, Basic

Layer 2 and Extended Layer 2. Release 2.0 has one

Layer 2 option, which includes all of the Extended

Laye r 2 capabil it ies.

Basic Layer 3 Switch Package

TMS contains the software components for Layer 3 IP

switches and routers. The Basic Layer 3 Package includes

all Layer 2 functions and integrates Layer 3 IP routing. It

supports routing over Layer 2 VLANs. TMS provides

complete management capability with support for

management consoles via Telnet or serial line, SNMPv1/

v2c/v3, and web-based management. The unique TMS

architecture ensures consistent views of management

informa tion no matter whic h access method is used. Each

package is provided in source code form and will run out-of-

the-box, enabling developers to radically shorten their

development time. The Agere Systems Switch Support

Package (SSP) is available from both WindRiver and Agere

Systems. With TMS, manufacturers can get new data

development costs and improving margins. In addition,

TMS can be used as a foundation for proprietary features

that differentiate a product from its competition.

Layer 2 Switch Package Components

The Layer 2 Switch Package is targeted at devices

requiring IEEE 802 LAN/MAN capability. All components

are fully integrated with VxWorks®, the Envoy™ SNMP

agent, and with each other. When an SSP is available for

the hardware platform, no additional integration is required.

Agere Switch Support Package (SSP)

With each switch packag e, customers will receive a switch

suppo rt pack age (SSP ) to work with the Ager e System s

network processing environment. The SSP is defined for a

specific switching chip set reference board and includes

drivers for a designated chip set, management CPU, and

other hardware devices.

A new SSP and BSP will be developed to integrate the

Agere Systems chip set into the TMS architecture. The

platform consists of a compact PCI (cPCI) chassis with an

MPC750 control processor running the TMS protocol stack

in a VxWorks environment. The Agere Systems

PayloadPlus chip sets are built into a cPCI controller

supporting eight 10/100 Ethernet ports initially. The

forwarding engines are updated dynamically with the

routing table entries of the TMS stack. TMS will use the

OSPF protocol to interface to the other routers in the test

network.
