Carrier-Class Features Provide Carrier-Class Benefits

The 7450 ESS represents a generational leap in carrier high availability enabling service providers to improve their network reliability with non-stop Ethernet services and ensure customer SLAs are preserved (see Figure 5). With its advanced feature set, the Alcatel-Lucent 7450 ESS provides a unique set of benefits for service providers, as described in Table 1.

Table 1. 7450 ESS Features Address Service Providers’ Requirements

Requirement

Feature

Increased revenue

Service-oriented architecture supports Ethernet services

 

with filtering, shaping and QoS on a per-service basis

 

not per port.

 

Distributed intelligence and control (versus traditional

 

infrastructure focused on broadband remote access

 

service [BRAS])

Benefit

Enables a full range of revenue- generating business and triple-play Ethernet services, which translates directly to profitable operation with customer-enforceable SLAs. Superior provisioning tools make it possible to bring new Ethernet services on line quickly.

Reduced capital requirements

Industry-leading density (by two to three times per rack)

 

compared to competing Layer 2/3 Ethernet switches,

 

with 10 Gb/s architecture available today — all at a

 

highly competitive cost

Improved density increases product lifespan, forestalling the need to upgrade or expand. The combination of hot-pluggable media dependent adapters (MDAs) and small form-factor pluggable (SFP) optics enables service providers to postpone capital expenditure until a customer order for a service is received. Reduced footprint saves expensive floor space.

Lower operating expenses

Industry leading Ethernet operations, administration

 

and maintenance (OA&M) features (e.g., service ping,

 

mirroring and trace route) for rapid service diagnostics

 

and troubleshooting

Reduced operating expenses and improved customer relations

Investment protection

Programmable fast path enables quick and painless

 

adaptation and upgrades to new and evolving

 

standards

Product scalability and programmable architecture ensure forklift-free upgrades, enable remote manage- ment, and reduce truck rolls (no technician deployment)

Ability to offer service guarantees

H-QoS enables a service-aware architecture that

 

provides per-service, per-subscriber, per-application

 

guarantees

Service providers can offer the kind of detailed SLAs their customers need for business-critical services

Improved scalability

MPLS-enabled Ethernet removes the 4,096 VLAN

 

limitation of Layer 2/Layer 3 Ethernet switches; MPLS

 

also ensures customer isolation

Satisfies the scalability requirements for offering prof- itable Ethernet services: scales to tens of thousands services.

Carrier-class reliability

Sub 50 ms failover enabling carriers to offer reliable

 

Ethernet services.

 

Non-stop routing and non-stop service features

 

ensure high availability.

Use of MPLS with Ethernet dramatically improves network stability, availability and performance. High availability essential for satisfying business and consumer markets

Time to market

Simplified service-level provisioning on a

 

per-cu stomer basis

Allows immediate definition of new services per customer
