Introduction
Networking
is
largely
about
connecting together devices so that
information can be shared between
them. Since the idea is to send data
from one place to another, a very
important characteristic of any
network is its speed: how fast can
data be transmitted and received?
This matter of speed turns out to be
only one of several issues that
determine the overall performance
of a network. The issue is complex
enough that I decided a section was
warranted to introduce the various
related topics and help you
understand how to look at network
performance in a balanced way.
When it comes to network
performance, there's a lot of hype
out there!
Network Performance Issues
In
the
computing
world,
performance is, in general, one of
the most often discussed but least
well-understood characteristics of
any system or hardware device. This
is true of networking as well. For
example, most people know the raw
throughput rating of their network
hardware, and may even start to
draw
conclusions
about
its
capabilities
based
on
those
numbers. Many, however, don't
realize that they will never actually
achieve that “rated” amount of
performance in the real world.
A network health audit can be used
to
enhance
overall network
performance, as part of routine

maintenance; to verify current conditions
prior to an expansion project or before
introducing new equipment or services; or
to ease integration when acquiring another
company’s network assets.
Our engineers can audit Network hardware
and software more efficiently with their
specialized expertise in optical networks,
test equipment, and processes, and
familiarity with large network operations,
ensures results that will simplify
multiservice
provisioning
and
troubleshooting while preserving network
integrity. Throughout the process, you are
free to focus on day-to-day operations and
service delivery.
Audit findings typically reveal opportunities
for immediate improvement and provide a
baseline for future comparison. Discovering
chokepoints and stranded bandwidth, for
example, are the first step in moving you
closer to maximum capacity utilization and
realizing the full potential of your network.
Optimizing
product
and
network
performance preserves maintainability,
enhances operational efficiency, and
contributes to high network availability.
Catalyst network audit also delivers
information that can help you meet
important business objectives, including ROI
and margin improvements, and lower the
total cost of network ownership.
Most of the other “subtle” issues related to
performance are also typically ignored or
misunderstood, such as the impact of
software drivers on hardware performance,
and the fact that certain applications need
more than just raw bit speed—they need
reliable delivery of data. But even beyond
all of this, one of the most important issues
related to network performance is
understanding what your needs are, to

make sure you don't spend too
much money for performance you
don't need—or worse, create a
network that can't meet your
requirements.

Performance is probably the
“mother of all buzzwords” in the
computer industry. There are many
people who consider it the ultimate
goal of any computer or computer
system, and by extension, any
network. A lot...
