It is important for a growing business to have a strong network that can support heavy data consumption. Most of the apps consume a lot of bandwidth and this can impact the network by slowing it down – a serious problem for the business during peak business hours.

As the business expands, implementing applications and network management can become a troublesome experience for IT Managers due to the network complexity. To expand connections the cost will increase similarly.

SD-WAN is a tailor-made solution for all these issues. With Micronova, you can experience simple, better performing, cost-effective, and secured network environments that can help in easy deploying and scaling of SD-WAN solutions.

Deploying Micronova’s SD-WAN services not only transforms your business’s network infrastructure but also boosts productivity and saves you enough time to focus on your business goals.

What is SD-WAN?

SD-WAN or Software-Defined Wide Area Network is smarter connectivity for your business that replaces the complex connection practices such as MPLS lines and eliminates dependence on single software solutions.

The SD-WAN being hosted on the cloud provides an infrastructure that allows traffic routing based on specific applications, policymaking, centralized management and helps achieve seamless connectivity

Benefits of SD-WAN adoption for your business.

Increased performance and availability:

It helps in enabling the use of multiple WAN transport services like MPLS, broadband, and LTE. Advanced SD-WAN platforms enable the use of multiple transports like- phone calls; video conferences; business transactions. It also indicates – higher productivity, a better quality of experience, fewer helpdesk calls, and reduction the downtime, improved customer satisfaction.

Enhanced agility and responsiveness:

some of the capabilities are- centralized orchestration, zero-touch provisioning, leverage internet services.

Centralized, simplified network policy configuration and management:

It can unify the WAN network functions like- routing, firewall, visibility & control, WAN optimization.

Improved WAN Security:

SD-WAN can provide segmentation that can isolate HVAC applications and guest WiFi

Lower WAN Costs:

The traditional and costly MPLS circuits are replaced with higher broadbands or DSL. SD-WAN simplifies WAN architecture and security


Why is SD-WAN?

Automated :Increase network agility by decreasing manual configuration steps through programmability and automation.

Fast : Improve performance by leveraging multiple network paths and faster broadband connections

Cost-Effective : Lower costs by eliminating reliance on expensive MPLS connections to remote sites.

SD-WAN Features

Zero-touch provisioning :

This feature enables automatic configuration and provision of network devices. This not only eliminates the hectic manual labor work involved but also saves time as the activation happens within minutes.

Encryption Key Rotation :

SD-WAN replaces conventional VPN based key rotations automatically that is programmed to make rotations every now and then without interrupting data plane traffic. This results in increased and better security, zero downtime, and elimination of manual intervention.

Application-aware routing, reporting, and analytics :

It helps identify distinct applications, analyze and report the performance of each application. This feature can provide significant performance and cost benefits for the company by constantly monitoring latency, jitter, delay, and many others.

Optimized Cloud Connectivity:

For geographically distributed enterprises with many branch office locations and multi-cloud connectivity typically backhaul cloud-destined traffic to the data center at headquarters or to a regional hub site for advanced security inspection. The aggregated optimized traffic is then directed to cloud Infrastructure-as-a-Service (IaaS) or Software-as-a-Service (SaaS) providers using a private high-speed link on the backend. In the SaaS scenario, the SD-WAN device is connected to the closest SaaS PoP(Point of Presence) to arrive at the best performing path by making real-time decisions.

End-to-End Microsegmentation:

this popular practice is used to secure applications running in the data center and cloud environments. They are separated based on policies and provide greater control to companies. Micro-segmentation allows the central policy server to automatically seperate the branch at times of attack to protect the rest of the network.

SD-WAN Components

There are three main components to this virtualized SD-WAN network:

    • The SD-WAN edge,
    • The Controller, and
    • The Orchestrator.

   -The SD-WAN edge is where the network endpoints reside. This can be a branch office, a remote data center, or a cloud platform.

  -An SD-WAN Orchestrator is the virtualized manager for the network, overseeing traffic and applying policy and protocol set by operators

  -The SD-WAN Controller centralizes management, and enables operators to see the network through a single pane of glass, and set policy for the orchestrator to execute.

These components make up the basic structure of an SD-WAN.

MPLS is expensive when compared to SD-WAN

With SD-WAN, you can expect significant cost reduction as it provides completely optimized, multi-point connectivity using distributed, private data traffic exchange and control points allowing users secure, local access to the services they need. These services can be from the network or the cloud.

Increased bandwidth

MPLS connections with 100Mbps + bandwidth and monthly costs will be too expensive.
SD-WAN enables your company to fully utilize multiple, high/low bandwidth, inexpensive internet connections constantly. This includes business-class cable, 4G, fiber, and so on. Your company experiences a fast internet connection by aggregating multiple connections.

Increased performance

SD-WAN can throttle low priority traffic on-the-fly and (for users with multiple ISP connections) always uses the fastest route to send the internet traffic using the circuit.
MPLS doesn’t execute any of the actions as they have a single network connection and as your Class of Service (CoS) setting is static restricts the ability to adjust on-the-fly.

Increased uptime

Aggregating multiple ISP internet and WAN connections at a single site will help your company achieve seamless circuit redundancy for your WAN even across multiple circuit types and within the network of services providers.
With MPLS, there can be failover to a secondary internet connection sometimes but it is typically not instantaneous and leaves us with no other backup plans.

Increased performance at small, remote, or international sites

Almost every company has sites that don’t suit well for MPLS network due to various reasons. The site may be too small ( due to the high cost of an MPLS circuit), or they cannot be serviceable by the MPLS provider (as the providers are in a remote or international location). Such scenarios force companies with MPLS to suffer less-than-desirable performance as the complete traffic is run over an IPSEC VPN.
On the contrary, SD-WAN provides agnostic and will deliver the same benefits, no matter which underlying ISP your company is using.

No longer imprisoned by your ISP

MPLS connection requires you to have its service provider at every site.
As a result, it takes a whole lot of reasons to make you want to go through the hassle of switching your company’s MPLS provider. You are bound in a difficult situation.
Whereas, with SD-WAN being ISP agnostic, your company can never be caught with ISP and can benefit from adding or removing ISP’s at any site and time easily.


What does SD-WAN mean ?

A Software-Defined Wide Area Network (SD-WAN) is a WAN architecture that is virtual and allows companies to securely connect users to applications using MPLS, LTE, and broadband internet services.

What are the advantages of SD-WAN ?

The major advantages of having SD-WAN is that
• It helps in improving the performance
• Provides robust edge-to-edge security
• Decreases complexity
• Cost reduction
• Advanced application visibility and control

Will the SD-WAN replaces MPLS as the future technology?

SD-WAN may reduce the usage extent of MPLS but cannot replace MPLS. This is because Software-Defined WAN encourages organizations to use the different connections for their underlay not because it is directly replacing MPLS.


No, SD-WAN is a software that is being used to determine your traffic flow, unlike VPN, it can’t create a tunnel for private browsing. It is used to configure network policies and manage the network.

What features does the SD_WAN device provide beyond basic connectivity ?

The features provided by SD-WAN beyond basic connectivity include:
• Zero-touch provisioning
• Encryption key rotation
