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
