Historically in the IT world, wide area network (WAN) implementations were limited to either leasing multiprotocol label switching (MPLS) and Metro Ethernet connections or establishing virtual private network (VPN) tunnels. Those options are still applicable but are no longer the only WAN technologies on the market. Up and coming Software-Defined WAN (SD-WAN) options are showing great benefits that should be considered when architecting a network.
Advanced compression and caching are a couple of the ways that SD-WAN optimizes networks. Hybrid versions can operate over public and private links, which helps cut costs and eases network congestion by running lower-priority (non-sensitive) data over the public portion of the network. This allows the more expensive private links to be reserved for critical data and network activity that cannot tolerate latency or interruption.
Enhance Connectivity and Network Speed
By taking the management and traffic-directing out of a device into an application layer, SD-WAN helps optimize the speed of packet flow through a network and better manage bandwidth. Policies, load levels, and slowdowns across the entirety of the network can be seen by the controller, which automatically computes the best path given the various factors involved. This can be done over multiple WAN connections concurrently for optimal speed and minimal latency.
A major advantage of using SD-WAN in a business network is the efficiency gained when adding on new services or devices. Rather than managing each device separately and taking weeks to provision a new router or server, the centralized administration module allows IT to rapidly integrate new hardware and have it up and running in record time.
An important new model that is starting to gather followers is using Virtual Dispersive Networking (VDN) technology. The main differentiators of VDN are that endpoints like devices and servers help direct traffic in addition to being the starting or stopping point of it. Also, VDN allows the SD-WAN to work over one Internet connection. Data is split into a number of paths and eventually is reassembled. The benefits of multiple streams are enjoyed without the burden or cost of more than one WAN link.
SD-WAN is growing in popularity as we begin to see more integrations with MPLS as well as a number of big technical names enteringthe arena. This not only helps drive down prices but also inspires competitive innovation, as in the case of the aforementioned VDN model. WAN costs can be a significant expense and switching to SD models will help reduce costs while improving productivity and building a better, faster network.
