SD-WAN

SD-WAN – also referred to as Software Defined Wide Area Network, is an application-aware, over-the-top WAN connectivity service that uses policies to determine how application flows are directed over multiple underlay networks, irrespective of the underlay technologies or service providers who deliver them.

What is SD-WAN?

SD-WAN – also referred to as Software Defined Wide Area Network, is an application-aware, over-the-top WAN connectivity service that uses policies to determine how application flows are directed over multiple underlay networks, irrespective of the underlay technologies or service providers who deliver them.

What are some common terms?

SD-WAN Controller

Centralizes management, and allows network admins to see the network through a single pane of glass; sets policies for the orchestrator to execute.

SD-WAN Service Orchestrator

A virtualized manager for the network, overseeing traffic and applying/pushing policies and protocols set by network admins.

SD-WAN Edge

A device in which the network endpoints reside. Can be located in a branch office, data center, or cloud platform. Actually handles the application flows and packets affected by the policies and protocols defined by the orchestrator.

SD-WAN Gateway

A virtual cloud gateway accessible over the internet that allows the SD-WAN edge at branches to communicate in the cloud. Will handle SD-WAN traffic and control and provides an extra layer of protection by insulating applications from interruptions during circuit flapping. Because the user sessions are connected to the gateway, the sessions are kept active during the interruptions as opposed to sessions connecting directly to the cloud service.

Application Flow

A sequence of application packets from a source to a destination; in this case usually office to office, office to the datacenter, or office to cloud platform.

Internet Breakout

When one or more of the underlay connectivity services is an Internet Service, certain application flows can be forwarded directly out to the Internet as opposed to sending it to another SD-WAN device.

Policies

A set of rules that are assigned to an application flow to determine how the packets are handled

Virtual Tunnels

The virtual point to point tunnels, built over the top of an underlay connectivity service such as internet or MPLS connecting various SD-WAN Edge devices to another Edge device or to an SD-WAN Gateway.
