Service-oriented architecture supports Ethernet services
with filtering, shaping and QoS on a per-service basis
n
ot per port.
Distributed intelligence and control (versus traditional
infrastructure focused on broadband remote access
service [BRAS])
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
Industry leading Ethernet operations, administration
and maintenance (OA&M) features (e.g., service ping,
mirroring and trace route) for rapid service diagnostics
and troubleshooting
Programmable fast path enables quick and painless
adaptation and upgrades to new and evolving
standards
H-QoS enables a service-aware architecture that
provides per-service, per-subscriber, per-application
guarantees
MPLS-enabled Ethernet removes the 4,096 VLAN
limitation of Layer 2/Layer 3 Ethernet switches; MPLS
also ensures customer isolation
Sub 50 ms failover enabling carriers to offer reliable
Ethernet services.
Non-stop routing and non-stop service features
ensure high availability.
Simplified service-level provisioning on a
per-customer basis
B
enefit
Enables a full range of revenue-generating business
and triple-play Ethernet services, which translates directly
t
o profitable operation with customer-enforceable SLAs.
Superior provisioning tools make it possible to bring
new Ethernet services on line quickly.
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.
Reduced operating expenses and improved customer
relations
Product scalability and programmable architecture
ensure forklift-free upgrades, enable remote manage-
ment, and reduce truck rolls (no technician deployment)
Service providers can offer the kind of detailed SLAs
their customers need for business-critical services
Satisfies the scalability requirements for offering prof-
itable Ethernet services: scales to tens of thousands
services.
Use of MPLS with Ethernet dramatically improves
network stability, availability and performance.
High availability essential for satisfying business
and consumer markets
Allows immediate definition of new services per
customer
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.
