What Are Software Defined WANs And What Benefits Do They Offer?
Software defined WANs or SD WAN are a type of network connection in which data is routed from a central location to remote locations by using the actual software as a method of transmission. In a software defined network, the administrator can control the transmission of data and monitor activity through the software that is responsible for the data connections. This provides a plethora of benefits and has numerous advantages which are discussed below.
Standard WANs or wide area networks use expensive equipment such as MPLS circuits that must be leased from a provider to send data from a central location to a remote one. Software defined WANs eliminate the need for leasing costly equipment to connect offices in far off locations from the IT headquarters thereby saving a company much money. Another key benefit stemming from software defined WANs is that there is no need to manually configure each and every router at every single office location, which is the norm for regular WANs now. This is incredibly expensive and time consuming. Instead with software defined wide area networks, an IT administrator can make the necessary programming changes from his IT office at a central location using the software.
Software defined WANs drastically cut down on truck rolls, that is the need for IT staff and technicians to travel to repair and readjust equipment such as routers at far off locations. Many companies can save lots of money by switching over from a regular wide area network and the restrictions that come with it to a software defined wide area network. Cost savings are the primary reason why companies are switching over.
Other benefits to software defined WANs include better and more reliable connectivity and the ability to manage connections from a central location. Changing to this software based connection is also relatively easy and has minimal disruption to an existing network. Often times, the software based wide area network can be incorporated with existing IT infrastructure and used with the current equipment.
Software defined area network products can also enable hybrid WAN transmission. This will allow a company’s IT department to take advantage of public infrastructure as well as private infrastructure to send data to its remote locations. The result is significant cost savings and much less maintenance in running the network for staff. Perhaps the greatest touted benefit of software defined WANs is that managing a network moves away from physical devices such as routers, circuits and switches and is done on computer software instead.
