The most important networking decisions are made long before the
first data transmission. What type of network will suit your organization
best? Most internetworks fall into one of two categories: those
that have been well designed and those that have merely been pieced
together over time. The perceptible difference between these two
types of networks illustrates the importance of good design. A well-designed
network shows consistently high performance in application response
time, the variation in response time, and other performance parameters.
Resilience
Your network should provide a resilient platform for the applications
it supports. A highly specified network might have to meet an availability
target of 99% for all applications with a zero-downtime requirement
for mission-critical applications. Ideally, the failure of any one
link or networking device along the client-to-server path should
not result in the loss of a client-server session. Automatic failover
to an alternate path should occur within a time interval short enough
to minimize the effect on existing sessions.
Scalability
When designing a network our engineers always recommend both software
and hardware that will not be outgrown as your users or data needs
expand.
A scalable network can support growth without having to be radically
redesigned. It can handle both the addition of users, network nodes
or sites and the addition of new applications with increased bandwidth
needs.
To get a feeling for how scalable your network is, ask yourself
the following question: What if my network had to serve twice the
number of users, twice the number of nodes, or new applications
that demanded twice the bandwidth? A scalable network can accommodate
this growth and change without significant changes to its infrastructure.
You should not have to redesign the fundamental network topology
or the technology you use to accommodate growth. New nodes and users
can be added to a scalable network in a simple building-block approach.
Adding new nodes, for example, should simply entail the addition
of a new section or block to an existing structure that serves as
the core or backbone of the network. To accommodate increased bandwidth
demands, you should be able to appropriately augment the LAN and
WAN bandwidth as necessary.
Security
Access to your information should be instantaneous but also controlled,
to keep prying eyes, both within and outside your organization from
viewing sensitive data. We use the industry's leading firewall and
directory services to enable security on the networks that we build.
For more information about security, please check our Firewalls
and Security section.
Stability
Our engineers will build in the maximum redundancy into every system
we install to mitigate down time. Our commitment to disaster recovery
after component failure is foremost.
Make the most of your office equipment - with a well-designed network.
A small team of capable engineers, who report on a general level
to management, should resolve the details of the network design
process no matter how large or how small your organization might
be. After thorough discussion on requirements with the client, we
design networks in our labs - not on the paper.
