Alcatel-Lucent 7450 Ethernet Service Switch | Data Sheet2
forwarding of IP/MPLS with granular
traffic management, scalable multicast
and high-touch packet services in a
single packet processing complex.
The FP packet processor complex
delivers the multidimensional scaling
required for large metro networks,
allowing the 7450 ESS to deliver the
speed, density and intelligent packet
processing required to enable high
performance IP/MPLS Ethernet services
on any interface port, with perfor-
mance predictability and per-subscrib-
er granularity.
Built to address the common require-
ments of both multiservice edge and
metro networks, FP supports all
7450 ESS interface options, so common
silicon is used across platform interface
modules, ensuring service consistency
with complete interoperability.
Purpose-built and optimized for
high-demand networks, FP technology
enables 7450 ESS to deliver a variety of
complex consumer, business and mobile
services with granular per-service and
per-subscriber controls. With each
IOM containing the powerful packet
pro cessing and traffic management
of FP packet processing complex, the
overall performance of the 7450 ESS
scales linearly with the addition of
each IOM to the Carrier Ethernet
Switch/Router chassis.
Extensible, programmable
and predictable
Highly extensible, FP technology
delivers the speed, depth and predict-
ability of a hardwired, fixed-function
ASIC, with the flexibility of complete
programmability and headroom to
enable rapid service adaptation. This
allows the 7450 ESS to easily evolve
to support emerging technologies,
proto cols and services through simple
in-service micro-code updates. This
flexibility minimizes the need for
premature hardware replacements,
significantly reducing the TCO and
greatly enhancing agility and speed-
to-service capabilities.
FP2 – The path to the future
of Carrier Ethernet services
The latest Alcatel-Lucent silicon
innovation is the FP2 network proces-
sor, which significantly extends the
power, capacity and versatility of
FP technology. Implemented on the
7450 ESS Input/Output Module 3-XP
(IOM3-XP), FP2 delivers up to 50 Gb/s
(full duplex) in a single packet
processing complex and can sustain
line rate forwarding with all services
enabled. FP2 provides 50 Gb/s clear
channel performance, doubling 7450
ESS wire-speed Gigabit and 10 Gigabit
Ethernet port densities while enabling
seamless support for future higher-
speed next-generation interfaces.
With FP2 technology, the IOM3-XP
further scales the comprehensive
range of service and traffic manage-
ment capabilities, such as Hierarchical
Quality of Service (H-QoS) queues, on
a single packet processor complex. As a
result, traffic management services
and queues are shared across all ports
supported by the IOM3-XP, providing
enhanced flexibility in networks where
subscribers or services may be heavily
concentrated on a few ports, while
other ports may be more lightly
loaded.
Modular interface flexibility
The 7450 ESS IOM supports two MDAs
per module, providing a simple and
flexible approach to platform configu-
ration. Enabling granular metro
network interface flexibility, a
comprehensive range of MDAs is
available to enable Fast Ethernet,
Gigabit Ethernet (GigE), 10 Gigabit
Ethernet and Packet over SONET/SDH
(PoS) in any combination on an IOM.
Consequently, service providers have
the increased freedom to construct
Carrier Ethernet solutions with highly
mixed interfaces and densities to meet a
broad range of customer requirements.
Field upgradability is further simpli-
fied, as hot-swappable MDAs can be
exchanged in service to change media
type and physical interfaces as required.
Because the IOM contains all of the
processing technology, most recon-
figurations only require the exchange
of an MDA containing the physical
interfaces, preserving a significant
portion of a service providers’ technol-
ogy investment. This flexibility enables
a high degree of investment preserva-
tion and leverage to further reduce
the TCO.
Virtualized service integration
IOMs support the full family of 7450
ESS ISAs. ISAs bring added intelligent
services by virtualizing advanced
services into the router chassis. ISAs
become fully integrated into the
network and share processing capabili-
ties, while reducing network complex-
ity, operating expenses, rack space
and power consumption. The ISA is
deployed in the same manner as an
MDA, and may be inserted into any
IOM slot. ISAs and MDAs may be
deployed simultaneously in an IOM.
Flexible 7450 ESS IOM options –
IOM-1 and IOM3-XP
Two 7450 ESS IOM options are available
— each version providing increasing
levels of per-slot throughput and
incrementally higher scale for high-
touch packet services. The 7450 ESS
Input/Output Module 1 (IOM-1)
leverages FP technology and delivers
up to 20 Gb/s (full duplex) with a full
range of scalable deep-touch services.
The 7450 ESS IOM3-XP lever ages the
FP2 network processor to deliver
per-slot throughput of up to 50 Gb/s
(full duplex) with an average of 8X
increase in service scale over the IOM-1,
while maintaining complete service and
platform consistency. The IOM3-XP
scales further to meet the needs of the
most demanding converged environ-
ments with the headroom for years of
feature expansion, bandwidth growth
and service scaling.
