SD-WAN Explained

What is SD-WAN?

SD-WAN: Software-Defined Wide Area Network (SD-WAN) is the application of Software-Defined Networking (SDN) ideas to wide-area connections, which include commodity Internet through DSL or cable, Ethernet-over-fiber, MPLS and leased lines.

The premise of SD-WAN is that enterprise traffic can be automatically and dynamically shaped and then forwarded across the most appropriate path based on network conditions, the security and quality-of-service (QoS) requirements of the application, and the cost of the circuit. Control is centralized, so changes in policy or provisioning can be managed from a single interface and automatically distributed to the relevant network device(s).

Why SD-Wan?

Private networks (MPLS, point-to-point, etc) cannot keep up with the constant changes in business needs and the move to hosted services. These networks are inflexible and cause friction in delivering solutions to the business. They are costly to maintain ($1000 for a single 5Mbs MPLS connection vs $80 for a 100mbs Internet connection) and require expensive staff to maintain. The Customer's end users already experience high speed Internet Connectivity at their homes, and now are expecting the same at the office.

SD-Wan provides a much less expensive and complicated option.

How does it work?

SD-Wan controls controls and ensures the quality of internet speeds and application traffic as it is streamlined both in to and out of the network, whether it’s coming from headquarters, a branch office, a single-site office, or even the home office of an employee.  This control is called Internet Quyality of Service (IQS) managing the end-to-end connection of the application - that is the traffic between the source at the user’s location (the VoIP call, videoconference, etc), and the server where the application’s software is actually running, i.e. the cloud or the enterprise’s data center.

What are the immediate advantages of Internet SD-Wan on the network?

  •  Eliminating network congestion,
  •  Reducing delays for all traffic types,
  •  Prioritizing interactive traffic:
  •  Voice first,
  •  Limiting jitter,
  •  Enabling reliability through a fully meshed network with active/active uplinks, and
  •  Encrypting traffic.

Which SD-Wan Partner does KTS Networks work with?

KTS Networks works with Maya Networks, who takes a simple approach for installing and dynamically adjusting traffic to changing network conditions, all without the intervention of any IT staff.  In the modern world you cannot assume a static network, capacity goes up and down over time, and load is a mixture of known/work traffic and unknown/consumer traffic simultaneously. Maya automatically adapts to network and load changes, providing continuous optimization with little or no administration.
