Network Infrastructure Design and Implementation
When working with many different companies, we find a
common thread running through the voice and data network of
most companies; a seemingly random growth and expansion
pattern. At least it seems random until you overlay the
growth of the corporation as a whole, then the pattern
emerges. The company's growth pattern is typically
shaped by emerging market trends, new products and services,
or customer demand. Unfortunately, company growth
drivers are usually very poor ways to expand a voice and data
network to optimize use.
Networks, when implemented correctly, are very hierarchical
in nature. This is what allows for redundant, symmetrical,
and optimal traffic flow. Additionally, hierarchical
networks allow traffic to reach the final destination in a
minimal amount of time and effort.
Internet Access- Our engineers can analyze and
recommend solutions that range from initial Internet access
through design that include redundant, load balanced, and symmetrical
BGP connections to multiple ISP's.
Intranet Access- Working very closely with your
business units, we can recommend necessary changes to help
streamline data and voice access. Of course anyone can
throw money at issues to solve them, but our professionals can
ensure our solution stays within budget and has an acceptable
Return on Investment.
Voice and Data Convergence- In today's highly
competitive marketplace, no one can afford to install,
maintain, and expand two separate networks of T1 pipes, for
voice and data. Unfortunately, that is just what many of
today's legacy organizations are attempting to operate.
The cost of installation is just the tip of the iceberg when
you consider the total cost of ownership; installation, moves,
changes to the network, and of course the recurring cost of
the connections. Our team of engineers can recommend
solutions that allow the two networks to converge into a
single highly available network that eliminates much of
the operations cost of the two networks.
Intrusion Detection- Intrusion detection is the art of
wading through mountains of IP data packets and application log
files to find suspect activity. While this may seem like an
insurmountable task when you consider the amount of data that flows
through an average Internet connected network daily, it is quite
manageable using today's advanced tools. Unfortunately,
detecting the bad packets is only the tip of the proverbial iceberg
in the area of Intrusion Detection. Once an actual intrusion
or compromise has occurred, you need seasoned veterans who know
how to handle every aspect of the situation. Questions like:
How do we recover the systems, is our data safe, what are the monetary
losses, and what criminal prosecution is possible should be handled
by IDS professionals who are able to see the big picture and react
accordingly. We specialize in partnering with our customers to
help define and establish process and procedure for handling the
entire Intrusion Detection System from installing the initial system
to documenting and auditing recovery procedures.
Firewall Audit- Firewall installation, maintenance,
upgrades, and operation require highly trained and certified
staff to help minimize the risks associated with operating an
Internet connected company today. Our specialists are
capable of assisting in all aspects of a firewall's lifecycle;
however, the routine audit is far and away the most important
part of any operational firewall's security
VPN- VPN, or Virtual Private Network, are the hottest new
buzzwords in the IT industry today. What are VPN's and how can
they be used to supplement our existing network? Our seasoned veterans
can assist you in understanding all of the why's, how's, and when's
of VPN integration.
Capacity Planning- Our professional engineers have
built entire careers upon analyzing existing traffic and predicting
emerging traffic patterns. We work closely with every customer
to proactively plan for future network capacity needs
just-in-time. This helps to ensure we don't order and install
circuits that are under-utilized or at the other extreme, have
circuits that do not have capacity to carry the demands placed upon
them. A good solid plan based on the historical data coupled
with strong analysis of future business needs are the linchpins to
success in this area. As always, a good working relationship
with our customers is key to any professional capacity plan.
Quality of Service- Today's converged networks demand an
extreme level of end-to-end quality of service. As the old
adage says, your chain is only as strong as the weakest link.
This has never been truer than in a converged network. One
over utilized link can destroy the quality of many voice
calls. Additionally, today's web based applications are
generating more bursty traffic than ever before however, many
current networks are still attempting to support real-time traffic
to mainframe systems. Without a high degree of control over
the quality of service running on a network, the bursty nature of
web traffic can overwhelm the low-volume real-time traffic.
Our engineers can work closely with your engineers to develop a
long-term strategy that will mitigate the effects of bursty traffic
and support voice and other real-time traffic even on your slowest
and most heavily congested links. Our tool chest has a number
of advanced traffic shaping, prioritization, and queuing strategies
that can be applied through careful planning and
implementation. Of course the final solution is only as good
as the response the end-users experience. As such, the
end-users are an integral part of quality of service planning and
Network Availability- Let's face it, your network is the
most important means you have to communicate with your
customers. It is also the most important network in the world;
it is after all yours. The art and science of predicting
network outages coupled with a solid network design incorporating
determinism, symmetry, and optimization are the key ingredients to
maintaining your most vital link to your customer.
What is determinism, symmetry and optimization and why are they
important in network availability? Determinism is the ability to accurately predict the flow of voice
and data traffic across the network even in failure
situations. This is important to ensure a network is first
resilient and secondly, not overloaded during a failure
situation. Symmetry is the ability to engineer a network so
traffic takes the same path back to the requestor as it arrived
on. The is quite possibly the most important ingredient in
maintaining quality of service because your users will surely let
you know when the voice traffic is unacceptable. Optimization
is the deliberate engineering of traffic flow to ensure the
deterministic and symmetrical data is traveling over the best path to
any given destination. All three of these items are critical
to consider to any Enterprise concerned with network performance.
When we initially engage many of our customers, we often find
they have built a network to serve a specific purpose but don't have
a good handle on how it is performing during peak operating
times. Additionally, little if any data is being collected to
assist in capacity planning, availability studies, and the people
responsible for maintaining the network are alerted to outages by
the end users.
Our team of software engineers are capable of partnering with
your network operations staff to install, configure, and operate
world-class tools such as HP Openview, TAVVE, and CiscoWorks to help
proactively monitor the network for outages.
Network System Monitoring Toolsets- HP Openview is beyond
question the industry leading tool to manage networks with SNMP.
When did a SNMP reportable event occur? What is affected by the
outage? Where is the down link or router? These and many other
questions are all easily within the realm of answers provided by
Openview. Our Software engineers can install Openview at your
location to immediately begin to answer those questions. Openview is
only the first step necessary to fully proactively manage your
network. Tools such as TAVVE and CiscoWorks are necessary to fully
manage your network.
Router/Switch Upgrade/Installation- Thinking about upgrading
your existing network or adding additional sites? We can assist you in many
ways. From the planning of required features of your network to
procurement, installation, and maintenance, our team of professionals are
there to assist you.
