Summary
As you can see, Network Processors offer a revolutionary
way of developing networking products that deliver
dramatic improvements in time-to-market and
time-in-market
TM
. Table 2 provides a comparison of Network
Processors to the alternatives discussed in this paper.
Only true Network Processors, like the C-Port C-5 Digital
Network Processor (DCP), offer all of these significant
benefits:
Complete programmability
—
At all protocol layers
from Layer 2 through 7, enabling adaptability to a wide
range of requirements at any point in the network
hierarchy.
Simple programming model
—
Leveraging well
known programming methods and languages (C and
C++) to allow faster time-to-market and portability of
code across platforms.
Maximum system flexibility
—
Maintaining a “soft”
approach to enable new services and standards to be
deployed with software-only upgrades.
Massive processing power
—
Required to fully and
robustly implement the key networking functions and
new services, and deliver wire-speed operation at high
bandwidths.

High functional integration
—
Implementing all the
network functions in a single chip solution to lower total
system costs.
Stable programming interfaces
—
Simultaneously
simplifying programming tasks and maximizing
software reuse for future product generations.
Third-Party support
—
Leveraging the proven
solutions of industry leaders in the software and
hardware development community for faster
time-to-market and better reliability.
Because of these advantages, networking vendors can
leverage the power and flexibility of software to apply a
platform approach to system development, and focus more
R&D resources on delivering the functions and services
demanded in today’s highly competitive market.
