This section is dedicated to FAQs related to SD-WAN and it shows the concepts that are more commonly related with the SD-WAN technology, and how they are implemented in the Teldat solution. Below you will see that we have divided this into seven sections to make the search much easier. Read the sections below and once you have seen the section you are interested in, hit the corresponding blue VIEW button, which will take you to the related list of FAQs.

Scenario & Data Model

This section describes which are the principal network scenarios where a SD-WAN solution fits, providing an overview of the main features and functionalities that can be found in SD-WAN.

In addition, it’s explained how the data model is built to add the capabilities to configure, manage and monitor a complete enterprise WAN network.

Some of the topics in this section are the following. Type of network access, SLAs, application identification, QoS…


Datacenter Edge


The Data Center is one of the main components in an enterprise network, and to implement a SD-WAN solution the Data Center Edge device requires some specific characteristics that are explained here.

The concept of a VPN hub, the alternatives in the redundancy implementation and other topics such as the scalability are answered.

Branch Edge

A SD-WAN solution simplifies the configuration, management and monitoring of a network which provides connectivity between branches and/or Data Centers. Thus, the branch edge becomes a key element of the solution. To select the proper branch device, it’s necessary to provide the all the technical and commercial information.

Topics such as the role of the branch edge device or the possible choices from Teldat portfolio, are covered here.


SD-WAN Controller


The SD-WAN controller is a new component in the network that comes with any SD-WAN solution. It is an important module to implement new capabilities.

The controller works based on the data model to provide basic and advance SD-WAN features as multi-tenancy, high available architectures, reduce point of failures…

All these concepts are explained here from a Teldat SD-WAN solution perspective.

Deep Packet Inspection (DPI) / Visibility

Control and visualization of the applications and services that are using our network, is one of the goals for the enterprises. The DPI allows the devices to check and analyze all the network trafficgoing through them, and provide that information in a user-friendly tool.

Furthermore, the identification of application at level 7 is a desirable feature for enterprises, because most of the applications, nowadays, are hosted in the public cloud.

How to identify and prioritize this traffic is covered in this area.


Self Provision / Configuration Synchronization


The centralized management of the devices in a SD-WAN solution, allows to provision them automatically. This process is known as ‘Zero Touch Provisioning’ (ZTP).

ZTP adds the capability to deploy a new branch edge or data center edge device automatically in the network, reducing the necessary expertise of the installer.

How this procedure is run in a Teldat SD-WAN solution is explained here.


Some other questions related with the SD-WAN features or the Teldat license model are answered.

Capabilities such as the device monitoring or the integration with third party elements (through API) are some of the topics which are covered in this section.
