Hub and Spoke Topology




It is sometimes referred to as the spoke-hub distribution paradigm. It is a system of links that where all the traffic is transmitted within the spokes that connects to the hub situated at the center. It is also known as a start network because of its arrangement that looks like a wire wheel. The hub and spoke topology is sometimes contrasted by the point to point transit model.




The network connectivity solutions are provided by the Internet Service Providers to link several physical sites that are located in varying geographical areas. In the large companies, the main office can be an example of a hub while the other physical sites can act as the spokes. The hub sites are used to connect the spoke sites and all the communications will always travel via the single hub.

The topology will always ensure that providers of the hub sites guarantee the connectivity of the subscriber. It will also advert the local linkage between the subscribers situated at the spoke provider edge routers.

Its primary objective is to enable the user keep constant the restrictions between sites. It reduces situations where spokes are locally switched by the provider edge router without transmitting the traffic via the hub site. Subscribers will not be able to establish a direct connection with each other. In this type of topology, the databases replicate through a single or more hub databases.

It is an approved topology that is viable for all kind of networks. In order to connect to the local or external network, all the traffic should be channeled via the hub to other spokes. The hub and spoke network are often in different categories and some tend to be small with one access point. It can also be large to allow connection with several Aps by the corporate enterprise.

The structure streams from the hub and a variety of the networks are often hub and spoke. All the mobile devices that will be revolving via the region will be characterized by the spokes.

The network administrators are useful in understanding more about the hub and spoke networks. They usually provide maximum security the fact that each device is in a different location from the others by use of an individual link to the wireless router. The physical topology of the network can be described by geometric shape which arises from the graphical mapping. Benefits of the topology include simplicity, centralization and guarantees higher performance.

They can easily be wired and are also affordable. The major downside is that failure of the single part located at the center darkens the entire network in situations where it fails to achieve the intended functions. It can also lead to lags in the communication which causes inconvenience. The hub and spoke WAN is also redundant due to failure of the single administrator.




This distribution paradigm is useful in various places such as telecommunication, freight and transport. It is also important in the distributed computing and describes the channels taken by the traffic long the spokes that are linked directly to the hub.
