SD-WAN Network Technology – Smart WAN Solutions – Top 15 SD-WAN Qualified Providers


SD-WAN (Software-Defined Wide Area Network)

SD-WAN (Software Defined Networking) is potentially a growing technology for WAN infrastructure, Engineers are preferring to go with new approach of managing a large enterprise network.But the challenge is large infrastructure with thousands of switches , Firewalls and hundreds of routers cannot simply move into SD-WAN overnight.

A software-define wide area networking is a virtualised concept of creating network layer by implementing overlay technology on top of hardware infrastructure.SD-WAN is a software-driven network approach, delivered as an end-to-end solution that brings a new level of efficiency and smart network operations to help your network operate at full potential.

Because, SD-WAN is abstracted from hardware piece of networking equipment, it is more flexible and agile than a standard WAN. It can operators remotely manage and quickly scale this overlay and running on application based platform of software-defined networking (SDN).

SD-WAN (Software-defined Wide Area Network) is an overlay technology (on top of the physical infrastructure) applied to various WAN connections such as broadband internet, 4G, LTE,  and MPLS. SD-WAN (Software-Defined Wide-Area Networking) is an intelligent software based technique to make wide area networks more intelligent and flexible.

Software Defined Wide Area Networking (SD-WAN) is agile and smart WAN technology that businesses continuity is looking the changing way that connect to the cloud.Now the organisations can move away from captive, proprietary hardware solutions, bringing flexibility and potential cost savings to their operations. 

SD-WAN  is a smart and transforming technology that simplifies the control of application-driven infrastructure.SD-WAN can be used to connect enterprise networks including remote branch offices and data centre over the different geographic locations over secure wan transport protocols.

SD-WAN uses a centralised control function to securely and intelligently direct traffic across the WAN. This increases application performance, resulting in enhanced user experience, increased business productivity and reduced costs for IT.

SD-WAN provide administrative control of network layers , applications flow , Policy and security is separated from underlaying hardware. SD-WAN network use a centralise admin consoles Network management and config controls by centralised consoles instead of physical locations of individual edge devices and infrastructures.

SD-WANs offer agility, flexibility, reduced operation cost (bandwidth and management), great connectivity to cloud and multiple consumption models.

SD-WAN (Software-defined Wide Area Network) is a virtualisation architecture of WAN allow enterprises to build a high performance network by using combination of transport services including MPLS, 4G/5G LTE and broadband internet services.

SD-WAN Key Advantages –

SD-WAN was developed with the cloud in mind.SD-WAN offers direct connectivity to the cloud from any location without injecting traffic through existing on-premises network infrastructure.The end-users get advantage of closer connectivity to the apps and data hosted locally in region or country.This way you can improve the end-user experience and provide them better network performance.

  • Reduce network infrastructure costs with transport independence across MPLS, 4G/5G LTE and broadband internet.
  • Improve application access performance faster, more reliable connectivity.
  • Policy based application based traffic prioritisation (quality of service – QOS)
  • Connecting branch offices to the Cloud network easy with secure.
  • Optimising user experience and efficiency for software-as-a-service (SaaS) and public-cloud applications.
  • Simplifying operations with automation and cloud-based management.
  • Secure private/public cloud connectivity, regardless of cloud platforms, applications and transports.
  • Zero-Touch Provisioning push configurations and policies are programmed once and pushed to all branch locations.

Why SD-WAN Market

Today, every organization meet applications requirements in order to migrating their application to the cloud platform and traditional network is not fit to support traditional WANs were never architected for the cloud.Enterprise business applications are no longer hosted in enterprise data centres, as they are hosted in different location.

Today most companies are migrating their branch office , Remote site and warehouses connectivity to SD-WAN. Because End-users demand direct connectivity to cloud hosted application instead routing through Data-Center. Business need to address these changes and create a robust and easy managed , agile and lower cost WAN solution.

  • On-premise – Data centres.
  • Public or private clouds – AWS , Azure
  • SaaS CloudOffice365 , Workday

Since , traditional network device like router that backhauls traffic from the branch to Data-Center to the internet , to the Cloud and back again does’t make sense to add extra network hop resulting adds latency and delay impairs application performance resulting in poor user experience and lost productivity. Employees often report that their business apps run faster at home or on their mobile devices than at the office.

Client-server model distributed application are perfectly binding with SD-WANs at an accelerating pace because they help businesses become more agile, increase business productivity and reduce the operational costs.

Software Defined Wide Area Network known as “SD-WAN” is a software defined networking (SDN) approach that elevates network traffic management away from hardware and on-premise management, to next generation software in the cloud for enhanced agility, control and visibility.
