The growth of your business has increased substantially over the last several months; however, the rapid growth has also increased the network congestion resulting in slower speeds and reduced performance which are affecting end-users directly; While maintenance and problem resolution have become extremely time consuming and arduous.
Do not fear; there is a solution- ‘Subnet Your Network.’
Often, the mere mention of subnetting evokes the ‘fight or flight’ response in many individuals or is dismissed too quickly because it is considered ‘too time-consuming,’ or ‘too complicated,’ ‘the math is too difficult,’ or ‘it is only useful for extensive networks.’
In reality, the benefits are wide-ranging for a subnetted network; From the troubleshooting of network issues to having a birdseye-view into the utilization of bandwidth, traffic patterns, network efficiency and atypical activity that can drain resources, it allows for more streamlined allocation of critical resources to vastly improving network security by applying more granular access controls in logical groups.
In contrast, a poorly designed network has higher support costs, diminished services and fewer solutions that can be supported, in addition to less than ideal performance. These issues can quickly become unruly creating a domino-effect potentially resulting in a network outage, which is not only costly and frustrating for your end-users, it can be exceedingly costly for your business as well.
Subnetting is the process of dividing up an extensive network into two or more smaller networks. By doing so, subnetting reduces broadcast traffic by having different devices communicate with different networks rather than all the devices on one network trying to communicate at the same time.
Smaller networks can be efficiently designed to represent logical groups for example as different departments – sales, marketing, and development. Alternatively, they can be divided into hardware devices – VoIP, servers, and workstations. These designs allow for the ability to isolate individual devices within the logical groups which are critical when troubleshooting issues within the network.
Also, a subnetted network allows for better control of the flow of traffic including Quality of Service (QoS) which can be considered the backbone of any successful business. QoS is increasingly vital across today’s’ networks. Not only is it a requisite for voice and video streaming, but it’s also an indispensable element in supporting the ever-expanding domain of the Internet of Things (IoT).
When it comes to security on a subnetted network, the benefits are extensive and extremely underrated.
First, by breaking the network up into multiple smaller networks, it is by far faster and easier to isolate compromised networks thus, containing and targeting current threats, preventing further damage to the remainder of the network. Secondly, today, data is the most critical asset to any company, and the loss or defilement of that data could be devastating to any business. Rather than having all resources on one network, it is safer to have a network with the critical business data isolated, secured from internal users who attains access into areas of the network that they don’t belong in addition to other potential bad actors. Even an unsophisticated attack could not only incapacitate the entire network but could also allow for a data breach with estimates that more than half of small to medium businesses never recover.
In conclusion, subnetting is a cornerstone of a well-defined strategy, an approved best-practice, and a comparatively easy and inexpensive way to reduce risk, gain profitability, improve adaptability and increase security.
