​​Exploring Various Types of Wide Area Networks (WANs)

Table of Contents

Wide Area Networks (WANs) play a role, in linking sections of a company over vast distances. They facilitate communication and resource sharing for businesses, regardless of the locations of their offices. Having an understanding of the different kinds of WANs can assist companies in selecting a suitable network that aligns with their requirements. Lets delve into the types of WANs and examine how they can be advantageous for your organization.

Conventional WAN

Traditional WAN setups are commonly utilized by businesses operating in locations. These networks typically depend on leased lines like T1 or T3 connections to establish communication channels connecting various sites. Such lines offer reliability and security, making them a favored option for organizations seeking performance and robust data protection.

A key advantage of WAN configurations is their stability. With lines in use, there is a reduced risk of congestion or interference from users. Nonetheless, this reliability comes at a price; leased lines can be costly for businesses with dispersed locations across extensive areas.


Multiprotocol Label Switching (MPLS) WAN solutions present an option compared to traditional WAN setups. MPLS operates by directing data between nodes based on concise path labels of network addresses.

This method accelerates the flow of data. Enhances the efficiency of the network.

MPLS Wide Area Networks (WANs) are recognized for their capability to prioritize different kinds of data traffic. For instance, a company can give priority to voice and video transmissions over information, ensuring that vital communications get the necessary bandwidth. This makes MPLS a favorable option, for businesses that heavily rely on real time communication.

Moreover, MPLS networks seamlessly integrate with network technologies, offering a solution that can scale alongside a business. Nevertheless, similar to WANs, MPLS can be expensive for smaller firms.


Software Defined Wide Area Networks (SD WAN) introduce an approach to WANs by utilizing software for managing network traffic. SD WANs employ software to oversee connectivity, administration, and services between data centers as remote branches or cloud instances.

A significant benefit of SD-WAN is its cost efficiency. By utilizing a mix of public internet connections, SD-WAN diminishes reliance on leased lines or MPLS connections. This adaptability enables businesses to incorporate affordable broadband connections alongside WAN links.

Additionally, SD-WAN provides visibility and management over network traffic.

Network administrators have the capability to oversee and control the network using a dashboard, which simplifies the task of enhancing performance and addressing any issues. This feature makes SD WAN a choice, for businesses seeking to boost their network efficiency and cut down on expenses.

Hybrid WAN

A hybrid wide area network integrates connection types like MPLS, broadband and LTE to establish an robust network infrastructure. By merging technologies, hybrid WANs can offer a combination of WAN reliability with the adaptability and cost efficiency of SD WAN.

Through a WAN setup, businesses can direct traffic over the suitable connection based on data type and prevailing network conditions. For instance, crucial applications such as voice and video can be transmitted via MPLS links, while critical data can utilize more economical broadband connections.

This strategy empowers businesses to optimize both their network performance and cost-effectiveness. Hybrid WANs are especially beneficial for organizations with networking requirements or those gradually transitioning from WAN setups to modern solutions.

Internet VPN WAN

Internet VPN WANs leverage Virtual Private Networks (VPNs) to securely link sites over the internet. VPNs establish encrypted pathways between locations to ensure data security during its journey, across the internet.

One of the benefits of internet VPN WANs is their cost-effectiveness. By utilizing existing internet connections, businesses can avoid the nature of leased lines or MPLS. This makes internet VPN WANs an option for companies or those operating on tight budgets.

However, due to their reliance on the internet, VPN WANs may experience reliability issues and be more susceptible to issues like congestion and latency. Despite these downsides, many businesses appreciate the cost savings and flexibility that internet VPN WANs offer.

In conclusion, selecting the type of WAN for your business hinges on factors such as budget constraints, network performance requirements, and your organization’s specific needs. While traditional WANs and MPLS are known for reliability and performance. Come at a cost SD WAN and internet VPNs present more economical alternatives with enhanced flexibility and control. Hybrid WAN solutions combine technologies strengths to provide a rounded approach that can adapt to evolving demands.

Having a grasp of the types of WANs along, with their benefits can empower you to make an educated decision that best serves your businesss connectivity and expansion goals. Whether you prioritize stability, cost effectiveness or a blend of both aspects, there is a WAN solution tailored to meet your requirements.
