WAN Explained: A Few Types of Wide Area Networking

When it comes to WAN, understanding its nuances and the various types available can be challenging for those, not in the networking or telecommunications world. In fact, simply knowing that WAN stands for Wide Area Networking can be a game-changer for many newbies in the industry. Here are some of the key facts you’ll need to know when it comes to the many different types of wide-area networking.

Point-To-Point Connectivity WAN

This is a very common type of WAN product on the market. In fact, these types have been around for many years now already. The reality is, point-to-point connectivity simply means that the connection will utilize two separate layer circuits to operate. Businesses also have the opportunity to choose the specific wavelength they want to use. As a result, some of the newer point-to-point connectivity measures will use very high-connection bandwidth models to connect to a wide area network. Businesses prefer this mode as it can guarantee a large level of bandwidth regularly.


Another important type of WAN that can be utilized by businesses is MPLS. In fact, multiprotocol label switching — otherwise known as MPLS — is a great option for companies when it comes to investing in a wide area network. Ultimately, this type of WAN is great for those looking for a carrier to actually own the network but deploys the router itself, and then manages all the policies for the customer. These types of specific WAN’s can be utilized for very reliable connectivity. As a result, carriers will typically guarantee strict service levels for any jitters, packet loss, and even latency.


Software-defined wide area networks (SD-WANs) are designed with two specific layers: the underlay and overlay networks. In fact, the underlay networks utilized by SD-WANs are ultimately made so that they consist of a large connection to the public internet and will typically leverage other WAN connections — usually once already mentioned here. 

Bottom Line

At the end of the day, there is nothing more important than understanding the nuances associated with WAN—wide area networks. In fact, for businesses, this is key for their success because they will know the best types to utilize for maximum success and an optimal connection for any business’s specific needs or purpose.
