One of the greatest challenges of OEMs building multiservice platforms (MSPs) is maximizing their return on
investment (ROI). With the massive network build-outs
of the past few years and falling bandwidth prices
putting pressure on margins, achieving better ROI can
be challenging, especially for the access and edge multiservice platform market.
The market is diverse with single MSPs accommodating
a mixture of ATM, Frame Relay, IP, MPLS, and PoS, with
port speeds ranging from subT1/E1 to OC-3 to full duplex
OC-48c/STM-16 links. Emerging applications including
packetized voice (VoIP) and 2.5G/3G wireless backbone
networks add further to the demands of scalability and
adaptability. And with converging applications (data/
voice/video) come issues of Quality of Service (QoS).
cannot easily adapt to new and evolving standards. The
ability to upgrade software versus forklift upgrades is
By implementing greater hardware integration and ‘soft’
implementation of functionality in an MSP product
design, vendors will see a significant increase in ROI. For
example, to be able to take a previous solution consisting
of two cards and replace it by a single line card, vendors
will automatically see ROI gains — and increasing port
density per card creates even better financial performance. And within that one line card, vendors need to
support both ATM/Frame Relay technologies and IP/
MPLS services, plus be able to upgrade functionality in
software. Both OEMs and their customers will benefit
from this type of solution.
A common architecture of a multiservice system today is
a rack or shelf with multiple flavors of line cards with a
common backplane bus and control processor card. The
backplane is often ATM-based. These line cards can be
dedicated to a specific function such as IP, ATM, or
Frame Relay or combine functions, such as ATM and
Frame Relay on a single line card. Interworking among
the cards is provided by routing to other cards within the
shelf across the switch fabric.
Motorola's C-Port™ network processor family enables a
new approach to MSP design that delivers a broad solution set within a highly integrated hardware and software platform providing flexibility and adaptability. With
C-Port family network processors, traffic management
coprocessors, and channel adapters, vendors can create
a hybrid line card capable of incorporating multiprotocol
capabilities and standards on a cost-efficient platform,
which can be easily integrated into existing and new
multiservice switches.
Typically, these solutions are not easily scalable in terms
of increasing bandwidths, implementing new interfaces,
or adding new services. Any solution for the access and
edge markets needs to offer a range of speeds and physical interfaces for today's applications and an easy
migration path for future applications — including a
more IP-centric network. In addition, today’s MSPs
The C-5e™ network processor (NP) consists of sixteen
programmable, full duplex CPs (Channel Processors).
Each CP can be programmed for a particular service/
application (ATM, Frame Relay, Ethernet, SONET, and so
on), and CPs can be aggregated for a wide spectrum of
data streams such as Fast Ethernet to OC-12c to OC-48c
on a single C-5e NP. To increase your bandwidth and

computing power, two C-5e NPs can used to scale your
system up to 10Gbps aggregate bandwidth. Multiple
C-5e NPs, used with a switch fabric, can achieve Terabits
per second bandwidth.
A single C-5e NP-based interface card design can be
built with a variety of different PHY interface types. For
example, the C-5e NP architecture can support up to:
• 16 10/100 Ethernet interfaces
• 4 Gigabit Ethernet interfaces
• 16 OC-3c/STM-1 interfaces
• 4 OC-12c/STM-4 interfaces
• 1 OC-48c/STM-16 interface (with assistance of the
M-5 Channel Adapter)
• 1 OC-48 interface connecting up to 48 logical interfaces
Cost efficiencies can be realized through integrated functions on the C-5e NP, including Ethernet MACs and
SONET framers, which speed system development, simplify device design, and lower total system costs. With
Motorola’s Smart Networks Alliance program, industrystandard interfaces enable system designers to gluelessly integrate additional hardware. For example, the
C-5e NP has a glueless interface to the IBM™ Packet
Routing Switch Fabric, in addition to conforming to standard CSIX-L1, Utopia 2, and Utopia 3 interfaces.
With the addition of Motorola’s tightly integrated Traffic
Management Coprocessors (TMCs), advanced QoS
configurations can be implemented such as active
queue management, policing and shaping, and
scheduling of flows — all programmed using the
C-Port family QoS APIs.
Software for ATM, Frame Relay, MPLS, SARing and
SONET can be implemented in the C-5e NP, which handles all the forwarding plane software. Through a tight
coupling to a host processor, such as Motorola’s
MPC750, which runs control/management plane software, even more advanced services can be achieved.
Further adaptability via a stable, standard API ensures
that system design investments can be carried forward.
Thus, one basic hardware design, matched with many
different PHY interfaces, combined with applications
that are fully software programmable yields a vast range
of different solutions leveraging a common platform. By
using the C-Port family in an MSP line card design, a
multi-year phased product delivery can be radically condensed, offering a massive time-to-market competitive
