There are many types of wide area networks at the moment. Most of them are used in items we see each day like the ATM protocol and others. The SD WAN experts have perfected the art of putting together very reliable wide area networks for firms of any type. Here are the main types of WAN that one can make use of.
Not to be confused with theautomated teller machine, the asynchronous transfer mode (ATM) is a telecommunications concept that is based on the ITU and ANSI standards. They are used in carrying data, video and voice signals to allow for communication.
- Cable modem
This is one of the most common types of wide area networks as per now. Cable modems provide bidirectional data communication between various locations based on radio frequency over glass (RFoG) and hybrid fire-coaxial (HFC). Both of these are radio frequency protocols. Cable modem is used in cyber cafes and other such locations.
The dial-up network employs the capabilities of the public switched telephone network (PSTN) to access the internet. The dial-up dials a phone number to establish a connection to the internet through an internet service provider.
Formally known as the digital subscriber loop but now called the digital subscriber line, it is a type of data transfer which uses telephone lines for the same. For most internet access issues, the most common of type of DSL used is the asymmetric digital subscriber line. It is a very useful and dynamic way of internet communication.
The integrated services digital network is a way of simultaneously transferring network services such as voice, data and video using public switched telephone networks. Although originally developed to carry out voice transfer, it was expanded in capacity and capabilities to bundle together various types of data types at the same time.
- Leased line
Popularly known as a data line or private circuit, the leased line is rented or leased in providing bidirectional communication between given points. They are simple lines that help in the transfer of data, internet, voice and other types of data at very affordable costs.
Both synchronous optical network and synchronous digital hierarchy (SDH) employ the use of fiber optic cables to transmit data as light packets or with light emitting diodes. It is a very fast way of communicating since light has the fastest speed or any substance. It is also growing in popularity by the day.
- SD WAN
SD WAN employs the use of software-defined (SD) bases in operating a wide area network. It is focused on lowering the costs of the network by ensuring that the leased lines are used in the place of more costly technology such as MPLS.
All these types of WAN can benefit from the SD WAN framework as it is very cost-effective and dynamic. With it, one does not have to change most aspects of their communication hence saving on time and money.
