Q Series Media Card
High Performance IP Forwarding Engine
for GRF Multigigabit Routers
The Packet-over-SONET/SDH (POS) OC-3c/STM-1 Q Series IP Forwarding
Media Card is an intelligent, self-contained IP forwarding engine that
provides high-performance POS support for the GRF®. The POS card’s
155 Mbps, full-duplex SONET/SDH port leverages the GRF switch 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 POS card features two
processors, a large route table, and memory
resources to deliver the performance and
capacity for demanding networks such as the
Internet. GRF Q Series cards feature Quick
Branch Routing Technology (QBRT) hardwareassisted route table lookup, which enables a
full route table lookup up to 100 times faster
than conventional software approaches.
■
Aggregate throughput of up to 90,000 packets
per second (pps)
■
Up to 150,000 route table entries
■
8 MB buffer memory (matches speed between
dissimilar media and accommodates crosscountry bandwidth-delay products)
Scalable design maximizes port
density and enables full system
functionality
The GRF dedicates 1 Gbps of internal bandwidth to each IP Forwarding Media Card,
maximizing the use of every media card in
the GRF without performance degradation.
In fact, the GRF scales linearly with every
additional IP Forwarding Media Card.
Point-to-Point Protocol (PPP), High-level
Data Link Control (cHDLC), and frame relay
provide the most efficient use of fiber optic
WAN bandwidth.
The expense, complexity, and wasted bandwidth associated with ATM networks is avoided
by using the low-overhead PPP, cHDLC, and
frame relay framing protocols. When using frame
relay, the GRF can perform both frame relay
switching and frame relay endpoint functions.
Independent, hot-swappable
architecture increases uptime
To ensure maximum network uptime, the POS
card was designed so that the GRF system operates continuously. 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.
