A wide area network is a telecommunications network that covers a wide range of geographical distance. This type of network is commonly known as WAN. Many businesses as well as government institutions use WAN. There are benefits from using WAN. Those benefits are relaying information to clients, buyers, even staff that are in different locations. This sort of telecommunications network makes it easy for any kind of business to carry out its day to day functions regardless of location. The internet can also be called WAN. WANs are computer networking technologies that are used to transmit data between different LANs, MANs, and other localized computer networking systems.
Of recent times, much focus is being placed on Hybrid WAN. This form of wide area network has been proven to be quite cost & time effective. Common LAN technology operates at a ½ layer. Ethernet and Wi-fi are prime examples of this. They are often geared towards localized networks, and cannot transmit data over thousands of miles. WANs are generally used to connect LANs with other types of networks. This makes it possible for users with computers to communicate with others in different geographical locations. Many WANs are built for one particular organization for private use. The internet service providers who build WANs create them to provide connections from an organization’s LAN to the internet. WANs are usually created with using leased lines. There are two routers apart of the leased lines. The first router is attached at the end of the leased line to the LAN on one side. The second router is attached within the LAN on the other side. Leased lines can be very expensive. There are other methods when creating WANs that are much more affordable. These methods include circuit switching and packet switching.
Cloud- based networking is desirable wan-based software. The cloud is transforming IT infrastructure and making it much more possible for even the smallest businesses to afford enterprise- class apps, computing, storage, constraints, and complexity without the cost of traditional networks. Some of the benefits of the cloud include no annual maintenance, no new software to purchase, pay-as-you-go subscription pricing, and anywhere access via internet connection. The cloud is changing WANs in two very important ways. Those ways are how distributed networks are managed, and how they are delivered. One of the changes that the cloud made is a software- as-a-service approach to network administration. The clouds management consoles and device configuration can be accessed via browsers. As well as make changes to remote network equipment using web APIs.
