A wide area network topology refers to describe the blueprint of network components and connections over a given WAN network. Therefore, now we will guide you about what is WAN topology and its examples with diagram; as well as different types of WAN topology in the networking without getting any hassle. At the end of this post, we will fully get know about all types of WAN topologies with ease.
What is WAN Topology?
WAN topology applies two concepts that involve to different but interrelated perspectives; one is the physical topology that represents the physical arrangement of network devices allows for data transfer from a source node to destination network. But, another perspective is the logically topology that refers how data move over the Wide Area Network.
A WAN design can be appeared complex, most such networks are depended around one of a some simple topologies. SO, here we will cover all types of WAN topologies over the computer network with ease.

Let’s Get Started!!
WAN Full Form in Networking
A WAN stands for ‘Wide Area Network’ that is connected a group of telecommunication networks , which are going to distributed across a enlarge geographical area spanning the multiple territories, nations, or cities so that the element network can get exchange the data along with the defined WAN networks group. WANs users are going to get range from educational institutes, government entities, and business to make communication and transfer data to several users consisting of clients, students, and supplier spread across the entire globe.
Types of WAN Topology
Here, we are going to explain about different types of WAN topologies in computer network; below shown each one in detail with its diagram as well, you can check them.
Point-to-Point WAN Topology:
This topology allows to connect one site to other; they are made connection directly. This kind of topology is also known as the Leased Lines. They are taken all services as lease from a service provider depend on your requirement for using bandwidth and distance in between two different sites; and shareable solution is not applicable. This topology system is inexpensive to other solutions.
But, there are some demerits like as:
- It has limited scalability option.
- It is getting vulnerability to failure in key components.
- The number of hops and alternative routers are constructed worse.
Important: Point-to-point WAN topology is going to use only two or three major regions.
Ring WAN Topology:
The ring topology structure is almost same as the point to point topology; but all sites are linked at the end of backbone to each other as well. This topology is less vulnerable for getting failure, and traffic can be also routed the opposite path around the ring, if any fault is occurred over the network.
- It is an enhancement over the point-to-point WAN topology; and it can offer the alternative routes.
- It is also inexpensive to all other topologies; except point-to-point WAN.
- It has also stability problems
- Having more costly compare to Point-to-Point topology
Star WAN Topology:
The star topology allows to connect all sites with helping a central hub. WAN hubs implement a technology called the concentrator router to make ensure data is sent to the proper destination point. In this topology, additional network can be added easily and scale up. It is most important consideration for business WANs; and it is also not vulnerable to a one cable failure breaking down the entire network, because it is totally depended on the concentrator router to be capable to run.
- It is more scalable and easily to attach any node with this topology.
- Every node is always getting two hops away from any other.
- It contains the one point of failure at the concentrator router.
Full Mesh WAN Topology:
This network topology allows to connect each sites with other sites one by one; so this topology requires more resources and costly. Beyond of this, it also requires an additional effort because the number of connections.
The number of connection, which is required for this topology, is will be calculated with this formula like as: N x (N-1) / 2
- High degree of dependability
- Fault tolerance
Full mesh topology can be become more expensive, cause of quantity of physical WAN circuits required and router that is going support specification design.
Partial Mesh Topology:
A full mesh topology has a variation that is involved a partial mesh topology, and this design will introduce a hierarchical approach to the topology that can be used when is getting the design at international networks. It offers the flexibility to build up variation into topology to meet geographic needs. WAN gets access sites connect to location points of concentration, then it will connect to a headquarter site along with a central data center. So this topology is most cost effective to full mesh topology.
Hub and Spoke WAN Topology:
This topology is going to use to connect multiple sites; and in this WAN topology, two actors play the major role as its names “Hub and Spoke“. Hub is a central network device at one side that is attached to all other devices. The spoke is the name of every of the other sites and devices; but they are not linked to Hub. There is not able to make connection directly in between the Spokes.
It is an expensive interface; and all spokes circuits are capable to share a common interface to hub by using the hub-and-spoke topology.
Dual-Homed WAN Topology:
The spoke routers are the dual-homed that is going to link redundantly to two hub routers in a Wide Area Network cloud. The dual-homed topology can be more expensive to use compare to a single-homed topology, because it is need some extra networking hardware like as routers and switches.
Therefore, dual-homed WAN topology is the best option for improved performance, load balancing and redundancy. Whenever, one of these sites get down, then connections will be continues because the load balancing is also offered between two links.
Multitiered WAN Topology:
The multitiered WAN topology is going to make use of such as:
- It has concentrator routers like as Star WAN
- It connects these concentrators together
- It might be made direct links in between other nodes.
- It allows to connect every major node to multiple concentrator router.
Benefits are: It is going to scalable because at worst just one link requires to be attached to few concentrators. It has improved performance, if there are more links; and this links can be make cause of traffic demands.
Flat WAN Topology:
A small organization has few branches at different location then it might be implemented a flat topology. This design structure is going to use point-to-point circuits in between the physical locations and forming a loop. If an organization has four branches at different regions, then each site may be linked on the WAN to two other sites placed at different states otherwise countries.
