Alcatel-Lucent OMSN Product Family 7
When the ubiquity of the optical-
network platforms deployed today
is considered, optical technologies
represent one of the most compelling
opportunities for service providers
to leverage their installed base and
deliver new revenue-generating
services (see Figure 2).
Alcatel-Lucent OMSN products can
be deployed with traditional MSPPs
from the Alcatel-Lucent portfolio
and emerging packet optical
transport devices in the Alcatel-
Lucent 1850 Transport Service
Switch (TSS) portfolio.
ISA-Ethernet Switch (ISA-ES)
modules enable new, highly-available
Layer 2 Ethernet service delivery
in the metro network through their
MPLS-enabled Ethernet.
With the ISA-ES equipped Alcatel-
Lucent OMSN nodes, service providers
can enhance their service offerings
with Metro Ethernet Forum (MEF)-
certified Ethernet services for business
and residential customers.
QoS for Ethernet
As well as mapping Ethernet
customer flows onto SDH network
resources through standardized
mechanisms, the ISA-ES series cards
introduce wire-speed classification,
policing and scheduling capabilities
on a carrier-class Ethernet switching
blade. These capabilities provide
a cost-effective solution for building
multiservice aggregation infrastruc-
tures that are scalable, reliable and
capable of per-service SLA/QoS
support with:
• Scalable service delivery based
on virtual local area network
(VLAN), Q-in-Q or MPLS
technologies, extended by
efficient SDH bandwidth-
management capabilities
• Sub-50 ms service resilience
based on SDH
• Per-flow and per-service SLA
guarantees offer accurate band-
width profiles according to
different customers’ applications,
to create a measurable, differen-
tiated Ethernet service portfolio
and increase service profitability
by ensuring QoS-specified Ethernet
service delivery in any network
condition, including faults and
congestion.
The ISA-ES blades allow service
providers to deliver more than just
Ethernet connectivity service over
the optical metro infrastructure.
These modules enable service providers
to climb up the value chain and offer
the new revenue-generating services
that both business and residential
users are demanding.
