nP3705
2.5-Gbps Network Processor with Integrated Traffic Manager
of feature-rich, wire-speed, Layer 2-7 applications
by combining the simplified nPcoreTM program-
ming model of all AMCC NPUs with open, layered
nPsoft Services, advanced development tools, rich
reference application libraries, and both simulation
and real hardware-based development systems.
Because the nP3705 allows easy API access to on-
chip coprocessors for complex tasks, customer dif-
ferentiating features can be created faster and with
fewer lines of code.

devices: nP37x0, nP34xx,
nP7250
unites the flexibility of the industry’s highest per-
formance network processing nPcore with the
most widely deployed and mature traffic manage-
ment technology. This unique combination
enables developers to deliver extremely fine-
grained control of subscriber traffic, without
impacting the ability to perform complex protocol
inter-working at media speeds. The nP3705 family
is designed from the ground up to provide soft-
ware compatibility with the earlier generations of
AMCC Network Processors. The single-stage pro-
gramming model dramatically simplifies software
development and troubleshooting for quickest
time-to-market.

The nP3705 is a 2.5-Gbps network processing and
traffic management solution. In addition to high-
performance packet processing and fine-grained
traffic management, the nP3705 includes special-
ized coprocessors that perform classification, polic-
ing, and coherent database management for
unparalleled line-rate performance. The devices
are offered in different speed grades to provide a
range of performance and cost options tuned to
the application.

•
•
OC-12/STM-4 ASAP applications ATM, IMA, FR, PPP, ML-FR/PPP
Up to 2.5Gbs line cards in access systems - DSLAM, FTTx
OC-12 SAR, ATM to Packet IWF
At the core of the MISSION value proposition is software that imple-
ments a wide variety of protocols on the chip set and enables flexible
potential additions to these base software features. AMCC provides
extensive offerings for the programmable nP37xx Integrated Network
Processors, including both rich off-the-shelf application software and a
complete development environment for extending this application
base if desired.
L3-L7 Applications
MISSIONTM — Multi-Service Internetworking Solution
The nP3705, combined with AMCC’s Amur (S1215) channelized framer
and ATM/HDLC/GFP processor extend AMCC’s MISSION multi-service
offering to applications up to OC-12/STM-4 rates. This solution enables
the development of single multiprotocol solutions in place of multiple
single-protocol solutions. The MISSION architecture provides equip-
ment vendors with solutions that enable their customers to save on
both capital and operational expenditures (CapEx/OpEx).
•
The MISSION application software includes ready-to-use Multi-Ser-
vice Switching software – ATM UNI/NNI, Inverse Multiplexing over
ATM (IMA), Multi-Link Frame Relay (ML-FR), Multi-Link PPP (ML-PPP),
Frame Relay and FR to ATM Interworking (FR IWF), MPLS Martini
encapsulation – as well as OEM customer-extensible libraries for the
hardware-resident aspects of higher layer applications such as IPv4
and IPv6 routing, and Layer 2 packet switching.
