Packet switching
The Alcatel-Lucent OMSN products share common
integrated service adapter (ISA) blades that provide Layer 2
packet-switching functions, adapting the SDH transport
infrastructure to the increasing demand for packet-based
broadband services:
• Offers MPLS-enabled Ethernet switching functions
and ATM-switching capabilities, with enterprise system
connection (ESCON), fiber connection (FICON) and
Fibre Channel (FC) interfaces for improved data-stream
connectivity and delivery of new IP-based broadband ser-
vices such as triple play, Ethernet virtual private networks
(VPNs), storage networking and 3G mobile aggregation

• Cost effectively manages and transports packet-based
data applications within the existing optical infrastruc-
ture, avoiding adding specific overlay data networks for
metro broadband aggregation
• Creates new revenues from current and future
competitive data services by enforcing and verifying
service level agreements (SLAs) based on embedded
Quality of Service (QoS) support (see Figure 1)
These capabilities transform the Alcatel-Lucent OMSN
products into the cost-effective multitechnology nodes
ideally targeted for optical metro networks where capacity,
infrastructure costs, reliability and packet-based services
play key roles in a user-centric broadband architecture.
