Solving Business Telecom Technology Pain-Points
SD-WAN is an acronym for software-defined networking in a wide area network (WAN). SD-WAN simplifies the management and operation of a WAN by decoupling the networking hardware from its control mechanism. This concept is similar to how software-defined networking implements virtualization technology to improve data center management and operation.
A key application of SD-WAN is to allow companies to build higher-performance WANs using lower-cost and commercially available Internet access, enabling businesses to partially or wholly replace more expensive private WAN connection technologies such as MPLS.
Multiprotocol Label Switching (MPLS) is a routing technique in telecommunications networks that directs data from one node to the next based on short path labels rather than long network addresses, thus avoiding complex lookups in a routing table and speeding traffic flows.
The labels identify virtual links (paths) between distant nodes rather than endpoints.
MPLS can encapsulate packets of various network protocols, hence the "multiprotocol" reference on its name. MPLS supports a range of access technologies, including T1, E1, ATM, Frame Relay and DSL.
Cloud-based SD-WAN offers advanced features, such as enhanced security, seamless cloud and support for mobile users, that result naturally from the use of cloud infrastructure.
As a result, cloud-based SD-WAN can replace MPLS, enabling organizations to save money who were once tied to more expensive WAN investments, and create new capabilities.

He can write backwards, and Mr. Drew Schulke does an excellent job explaining to us the history of the WAN, MPLS and Software Defined WAN and their relationships.

A special thank you to one of our Strategic Partners for a very practical illustration about how the SD-Wan equipment functions.
