5 Reasons Your Network Infrastructure Needs an Upgrade

Posted by Larry Tsikada on April 30th, 2019

Small to medium companies are often skeptical about investing in technology. They usually refrain from experimenting and prefer to stick with what they have always used. However, holding on to traditional practices can be detrimental. If you want to stay competitive in your business, it’s crucial to step out of your comfort zone.

A network upgrade brings benefits which are often worth the investment. It increases efficiencies within the IT department. With the ever-increasing needs of network infrastructure, reliability, performance, security, expansion, and flexibility are the 5 reasons that call for an upgrade.


Your client might use a variety of multimedia and unified communications over IP such as Instant Messages, Telephones, and Videos. It is, therefore, crucial that they have a reliable internet connection and high-functioning network devices. A reliable network infrastructure offers the same services even during a failure.


Network performance holds equal importance when it comes to executing seamless service delivery using an IT network. The measures often considered important are:

  • Bandwidth, commonly measured in bits per second is the maximum rate of data transfer across a given path
  • Throughput, the actual rate that the data can be transferred from one location to another at a given time
  • Latency, the pace at which the content traverses within a pipe across any node
  • Jitter, any variation in packet delay at the receiver of the information
  • Error rate, the number of corrupted bits expressed as a percentage or fraction of the total sent

An effective way to enhance network performance is by improving your LAN performance. Using 100-Megabit or Gigabit Ethernet switches with Layer 3 and VLAN capabilities can play a vital role in achieving enhanced network performance.


It is critical for businesses to ensure secure endpoints by equipping security controls that can work proactively, to refrain from potential cyber attacks. Every organization today requires a degree of network security solutions in place to protect it from the ever-growing landscape of cyber threats. An efficient and stable network security system is essential to protect data as there is no network that is immune to attacks.

Types of network security:

  • Application Security
  • Web Security
  • Wireless Security
  • Endpoint Security
  • Data Loss Prevention (DLP)
  • Email Security
  • Firewalls
  • Network Access Control (NAC)
  • Mobile Device Security
  • Network Segmentation
  • Virtual Private Network (VPN)


As a business grows, it brings along the requirement for additional employees, IT infrastructure to support it, including networks, data centers, and the power to run them. They need networks that are sophisticated and more robust to support the increasing number of users and applications. A good understanding of why an organization is expanding allows them to face the challenge of how to support growth. Also, a thorough site survey including floor plans, security issues, energy resources, wireless networking and the location of wiring closets could be done to get an idea about the network requirements.


Today, businesses must ensure that their network connection is flexible with wireless networking for employees who are required to roam within the organization premise, Virtual Private Networks (VPNs) for those working at home, and even cloud-based file sharing for those who work offsite or in different locations.
