ATM OC-12c/STM-4
Q Series Media Card
High Performance IP Forwarding Engine
for GRF Multigigabit Routers
The ATM OC-12c/STM-4 Q Series IP Forwarding Media card is an
intelligent, self-contained, high-performance IP forwarding engine
for the GRF® Multigigabit Router. The card’s 622 Mbps, full-duplex
ATM OC-12c/STM-4 port leverages the GRF Multigigabit Router to
deliver packets at full line speeds.
Integrated IP routing capabilities
optimize network performance
Within the GRF distributed architecture, each
intelligent IP Forwarding Media Card makes
Layer-3 decisions. The ATM OC-12c/STM-4 card
features dedicated hardware processing for both
the transmit and receive packet-forwarding
tasks, a large route table, and memory resources
to deliver the performance and capacity for
demanding networks such as the Internet.
Lucent Q Series cards feature Quick Branch
Routing Technology (QBRT) hardware-assisted
route table lookup, which enables a full route
table lookup up to 100 times faster than software-based approaches.
■
Aggregate throughput of up to 590,000
packets per second (pps)
■
Up to 150,000 route table entries
■
8 MB buffer memory (4 MB input buffer and
4 MB output buffer; matches speed between
dissimilar media and accommodates crosscountry bandwidth-delay product)
Scalable design maximizes
port density and enables full
system functionality
The GRF Multigigabit Router dedicates 1 Gbps
of internal bandwidth to each IP Forwarding
Media Card, and each media card contains a
dedicated IP forwarding engine. This enables
the use of every OC-12 slot on the GRF without
performance degradation. In fact, the GRF
performance scales linearly each time an
ATM OC-12c/STM-4 IP Forwarding Media
Card is added to the router. Fully loaded, the
GRF 1600 can route 100 percent of the useable
OC-12 bandwidth for all 16 cards.
Independent, hot-swappable
architecture increases uptime
To ensure maximum network uptime, the
ATM OC-12c/STM-4 media card is designed
so that the GRF system operates continuously
regardless of media card status. The card is easy
to install and maintain, and it automatically
configures itself after initial installation.
Since each card functions independently, the
system continues to operate if a problem occurs
on one of the cards. GRF media cards are hotswappable, allowing card replacement and
auto-configuration while the system continues
to operate.
