SD WAN is a term for Wide Area Networking (WAN) technologies used to connect geographically dispersed locations. SD WAN technology allows companies to use multiple internet connections, including broadband, 4G, and LTE, to create one logical network. This allows companies to have more control over their network, and to optimize performance and reliability. MPLS is a networking protocol that directs data through a network of nodes, or routers, as efficiently as possible. MPLS creates a "labeled" path for data to travel, which helps to ensure that the data arrives at its destination as quickly as possible. MPLS is often used in conjunction with SD WAN technology, as it can help to improve the performance and reliability of the SD WAN network.
There is no clear-cut answer when it comes to deciding which technology is the better option for your business: SD WAN or MPLS. Ultimately, the best choice depends on a variety of factors, including your budget, network requirements, and overall goals.
