MULTI-SERVICE METRO ROUTERS: RS 8000/8600

RS 8000/8600

Flexible Multi-service

Metro Routers

Product Overview

The RS 8000 and RS 8600 are high-perfor-

mance, all-purpose metro routers capable

of providing both access and aggregation

services in any type of metro network. Among

the most widely deployed routers in the metro,

the RS 8000 and RS 8600 combine powerful

service creation capabilities with a full range

of optical and

legacy interfaces in a compact,

NEBS-compliant

platform. The RS 8000 and

RS 8600 provide

an ideal service-provisioning

platform for service

providers in the metro,

featuring powerful service creation tools

such as Riverstone’s metro-optimized MPLS,

hardware-based rate limiting, and connection-

oriented accounting architecture.

Versatile connectivity is a major factor in

the success of the RS 8000/8600. These

products are capable of delivering services

over the full range of media types found in

metro networks, including TDM, RPR,

Packet over Sonet/SDH, ATM, and Fast

and Gigabit Ethernet.

Applications and Positioning

The RS 8000 and RS 8600 act primarily as

versatile aggregation routers. They are typically

positioned in the metro POP or at the data

center gateway, where they serve to aggregate

traffic over a variety of media types and provide

uplinks to the Internet core edge. These

products are also suitable as high-density

access routers for large MTUs and enterprise

campus environments. Other, more specialized

applications include broadband aggregation

and aggregation/routing alongside a voice

gateway as part of a class 4/5 switch

replacement in the central office.

Like all Riverstone routers, the RS 8000 and

RS 8600 share the same core technology,

including a common set of ASICs and the

same system software. The RS 8000 and

RS 8600 also use the same interface cards.

The principal distinction between the

RS 8000 and the RS 8600 is size and

capacity. The RS 8000 features a 5-rack

unit chassis with 8 slots and a 32 Gbps

backplane. The RS 8600 features an 11-rack

unit chassis with 16 slots and a 64 Gbps

backplane. Which product is appropriate

for a given application will depend on the

port density and throughput requirements

of that application.

Key Benefits and Selling Points

Interoperability across legacy and emerging backbone media: Effective metro

aggregation requires the flexibility to aggregate traffic of all media types and provide a range

of uplink alternatives. The RS 8000 and RS 8600 are all-purpose metro aggregation routers,

supporting an industry-leading set of WAN connectivity options. And the flexible, modular design

of the RS 8000/8600 means service providers can migrate seamlessly from legacy to optical

infrastructure. Available interfaces include ATM, Packet over SONET/SDH, RPR, T1/E1, T3/E3,

10/100 and Gigabit Ethernet (see table on page 9 for available interfaces).

Robust services provisioning: The RS 8000 and RS 8600 support an unrivalled range of

service-enabling technologies, allowing service providers to seamlessly extend value-added

services across the metro to the core edge. Hardware implementations ensure wire speed

performance with all features enabled. Key service-enabling technologies include:

• Carrier-class routing, featuring Tier 1-certified implementations of OSPF, BGP-4, and IS-IS

• Metro-optimized MPLS in hardware, enabling the RS 8000/8600 platform to act as an LER

or LSR to extend VPN and traffic prioritization services across the metro, across the country,

or around the world

• Reliable support for the full 4,096 VLANS specified in 802.1Q, and VLAN to LSP mapping

• Hardware-based rate limiting on every port, enabling dynamic bandwidth provisioning at

both the wholesale level and the subscriber level

Carrier-class reliability: Network reliability is a paramount concern in the metro POP or

data center. The RS 8000/8600 is a fully NEBS-compliant, carrier-class router with a range of

battle-tested redundancy mechanisms. Key reliability features include:

• NEBS level 3 certification

• Redundant CPU, power supplies and switching fabric

• Hot-swappable media modules

• Standards-based virtual router redundancy protocol (VRRP)

• Highly stable, Tier 1-certified routing code

• Self-healing route paths (OSPF multipath, MLPPP, and Smart Trunking)

Services billing at the customer site or POP: Retail service providers need accurate wire

speed accounting for each subscriber at the access edge, while wholesale service providers

need reliable billing for their carrier customers in the metro POP. Whether the RS 8000/8600 is

deployed as an access router or as an aggregation platform, it leverages Riverstone’s unique

billing and accounting technology – the only irrefutable services accounting solution on the

market. Key accounting features include:

• The industry’s only connection-oriented (TCP-based) accounting solution ensures that

critical accounting data will never be lost

• All accounting features in hardware for wire speed network

performance with accounting enabled

• All RMON I and RMON II groups on every port for

unmatched granularity of accounting data

High port density: Compact, high-den-

sity routers enable service providers to

save colocation costs in the metro POP or

data center and reduce the number of ele-

ments in their networks. The RS 8000 and

RS 8600 deliver high port density in a

compact, modular, chassis-based platform

capable of scaling with customer needs.
