OVERVIEW OF COMPETITIVE POSITIONING

highly stable implementations of BGP-4,

OSPF, and IS-IS have been certified by Tier 1

carriers worldwide and are fully interoperable

with Cisco and Juniper core routers.

No performance degradation with

features enabled: Rich service capabilities

have no value if the network slows to a crawl

when they are activated. This is precisely

the problem with software-based service

solutions. Because Riverstone implements

all of its advanced service creation features

in the ASICs, service providers never have to

choose between features and performance.

Lab tests consistently confirm that

Riverstone outperforms the competition

with service features enabled.

Unmatched range of service-enabling

features: Value-added services require the

right technological enablers. Competitors’

products lack many of Riverstone’s powerful

service-enablers and often feature unreliable,

unstable implementations of others.

Additionally, many competitive products

implement some or all of their technological

enablers in software, producing the perfor-

mance degradation problems described

above. The following table summarizes

some of Riverstone’s distinctive service-

enabling features.

Service Delivery over Any Network

Unsurpassed interface support:

The physical infrastructure of the metropolitan

area network consists of a medley of different

media types, and service providers must often

make do with whatever type of media happens

to be available. Riverstone offers the broadest

range of interface options in the industry,

enabling service providers to connect to

whatever media type they encounter, including:

• T1/E1 (clear-channel and channelized)

• T3/E3 (clear-channel and channelized)

•

Packet over SONET/SDH (OC-3 to OC-48)

• ATM (OC-3 to OC-12)

• WDM (CWDM & DWDM)

•

Fast Ethernet (TX, FX, SX, LX-IR, & LX-LR)

•

Gigabit Ethernet (FX, SX, LX-IR, & LX-LR)

• 10 Gigabit Ethernet

• SRP/RPR (OC-48)

Market footprint and time-to-market

advantage: Because service providers

simply can’t afford to wait for fiber pulls, the

ability to connect to existing infrastructure

translates into a substantially wider market

footprint and often provides a first mover

advantage.

Billing and Accounting for Services

Industry’s only irrefutable accounting

solution: Services accounting means more

than simply gathering general statistics

on average network usage; it requires

accounting data that is sufficiently detailed

and reliable to support an itemized customer

bill. That means gathering data with

irrefutable reliability. Because competitors’

products gather accounting data through

connectionless (UDP-based) solutions, critical

accounting data that is dropped en route to

the accounting server will never be re-sent.

Riverstone offers the only connection-

oriented (TCP-based) accounting solution

on the market, ensuring irrefutable

accounting and reliable services billing.

Unmatched granularity of accounting

data: More granular accounting data

enables a broader range of options for

customer billing and generates detailed

insights into customer behavior that can

be used to develop additional services.

Riverstone is the only vendor to support all

RMON I and RMON II groups in hardware

on every port, capturing a level of accounting

information that competitors cannot match.

Accounting enabled: Because Riverstone’s

accounting solution is implemented in

hardware, performance never suffers when

the accounting features are activated.

Overview of

Competitive Positioning

Industry Background

Service providers today confront severe

economic challenges. Bandwidth is

becoming a commodity, while operational

costs continue to rise. As a result, service

providers are increasingly interested in

infrastructure solutions that can help them

develop new revenue streams and reduce

the expense and complexity of their networks.

This is where Riverstone Networks can help.

Market Focus

Because Riverstone is focused exclusively

on service providers in metropolitan area

networks, the company has a unique

understanding of the challenges and

requirements of this market. Every aspect

of its products – from service features and

hardware performance to the size and

shape of the boxes themselves – has been

designed to help service providers increase

revenues and decrease costs in their

metro networks.

Riverstone Products

Deliver Unmatched

Revenue Potential

Service providers understand that the key

to improving their revenues is developing

new value-added services. Riverstone

specializes in building routers that convert

raw bandwidth into profitable services for

Metropolitan Area Networks. Supporting

profitable services requires three key

capabilities: enabling the services them-

selves, delivering those services over

any network, and accurately billing and

accounting for those services. Riverstone

has significant competitive advantages

in each of these areas, and is the only

infrastructure vendor – bar none – capable

of delivering all three of these requirements

to customers.

Carrier-grade routing is the foundation of any

service creation platform. Riverstone’s Robust,
