The
C-5e network processor (NP)
, Motorola’s
second generation network processor in the C-Port
family, is the most integrated, flexible, and functionally-
rich processor for developing and deploying advanced
services for next-generation networks. With its 5Gbps of
bandwidth and more than 4500 MIPs of computing
power, the C-5e NP more than satisfies the demanding
communications requirements for intelligent network
services, such as classification, traffic management, and
interworking functions.
The C-5e NP is compatible with Motorola’s Traffic Man-
agement Coprocessors (TMCs) to provide unprecedented
Quality of Service (QoS) capabilities. What’s more,
Motorola’s M-5 Channel Adapter can extend the
C-5e NP’s data bandwidth reach to support full-duplex
OC-48c/STM-16 and channelized applications, enabling
high-speed network services.
The C-5e NP also integrates robust programming inter-
faces, a comprehensive development environment, and
third-party support from Motorola’s Smart Networks
Alliance to provide a platform approach that can simplify
and speed the development of full-featured networking
applications today, enable faster development within
and across product families, and provide a smooth migra-
tion path to future product generations.
SOFTWARE-OPTIMIZED NPU ARCHITECTURE
The C-5e NP was designed from the ground up to provide
a simple and robust programming model. It enables
complete programmability of forwarding plane tasks in
C-language using Applications Programming Interfaces
(APIs). To support this programming model, the
interactions among subsystems of the architecture are
very efficient with integrated coprocessor acceleration
for common tasks such as classification, traffic
management, buffer management, fabric interfacing,
and supervisory processing.
Traffic typically enters the C-5e NP through its 16
Channel Processors (CPs), each of which can
accommodate up to an OC-3’s worth of bandwidth. Each
CP contains a transmit and receive Serial Data Processor
(SDP), which operates like a VLIW engine, and a RISC
Core that is used for any application-specific purpose.
The SDPs control programmable external pin logic,
allowing them to implement a wide variety of Layer 1
interfaces including connection to T/E-Carrier framers,
10/100 Ethernet PHY (RMII), Gigabit Ethernet PHY (GMII
or TBI), OC-3/STM-1 PHY, OC-12/STM-4 PHY, and the
M-5 Channel Adapter, a Utopia 3/PoS PHY interface that
can support OC-48/OC-48c/STM-16 MPHY capabilities.
Ethernet MACs and SONET framers are embedded in the
SDP architecture.
At Layer 2, the SDPs can be independently configured to
support Ethernet, Packet over SONET (PoS), HDLC
streams, ATM, Frame Relay, FibreChannel, or virtually
any format, including MPLS and other encapsulations.
