Vendors enhanced WAN optimization techniques and integrated them into a new package.

It stemmed from software-defined networking technology that separates the control plane from the data plane and centralizes control and management.

Enterprises decided to stage a coup against MPLS service providers.

Vendors got bored and decided to throw the WAN industry for a loop with a new, exciting acronym.

True

False

It runs on a mix of network connections

It provides high cost and low speed in connectivity

There's no possibility of latency and packet loss when directly connect to the cloud

It does not relies on virtualized overlay

A wide area network.

A physical or virtual SD-WAN appliance at each site.

Knowledge of your company's WAN traffic patterns and existing WAN links.

All of the above.

True

False

Application-aware routing for best path selection and failover.

Centralized management and real-time monitoring.

The ability to use multiple WAN connections, like MPLS and broadband internet.

All of the above.

It is mostly rely on dedicated MPLS connections

It measures traffic and selects the best route for each data packet in real-time

It is hardware/software combination and offers added flexibility.

It have a centralize controller

True

False

True

False

It consists of multiple single function devices which connect via different WAN link

Changes to control plane cannot be grouped

Each endpoint managed separately

SDWAN routers can combine the bandwidth of multiple WAN connection

It is a physical network connection

It requires hardware at each end of the network

It abstract control of WAN connection into a software layer

The configuration and provisioning are not split into a seperate lane

Firewall capabilities and network segmentation.

Physical walls around each site location, with moats for good measure.

Traffic encryption and VPNs.

Regular system updates and patches.
