SD-WAN for Uninterrupted Network Performance

Top 2 sd-wan vendors

List of the top SD-WAN vendors and providers for 2021

In a software-defined wide area network (SD-WAN), the concept of software-defined networking is implemented in the network. In this way, there is greater ease of administering and operating the WAN by decoupling the basic networking equipment.

In addition to being cost-effective, the SD-WAN is also advantageous to enterprises. To increase bandwidth capacity between sites, fiber optic cables are deployed. Anyhow, the installation is expensive, complex, and can bring about legal disputes over underground cabling entries, etc. As SD-WAN works over the internet, it is usually the preferred method for connecting sites that do not have private networking cables.

Furthermore, router-based WANs can be configured more easily since no complex configuration is required. SD-WANs can provide consistent connectivity between cloud resources and on-premises resources using such features.

WAN software runs on a server, appliance, or cloud service that works as a gateway to send enterprise traffic out to the Internet. Network traffic and the network itself are typically protected by encryption.


The SD-WAN technology has advanced in various ways and from different sources. It can be seen in the devices that are accessible. Others follow their DNA to the security side while others began in routing, WAN optimization, or other networking-related areas. This results in a huge variety of capabilities for different products and services.

A further difference in products and services is the way they are delivered. Some SD-WAN solutions are provided through appliances, some through software sitting on a server, and others through cloud-based SD-WAN. It is impossible to find the best way. The choice of architecture is based on the enterprise’s architectural preferences, the vendor mix, and other factors.

Top 2 SD-WAN Vendors to ensure better network performance:

  1. VMware

In terms of VMware SD-WAN, it has advanced from its VeloCloud integration. To handle the deployment and management of network gadgets, cloud-hosting is used, as is traffic routing between data centers and the cloud. Connecting users to data centers and cloud-based applications from anywhere within the network combine the bandwidth of broadband and existing WAN connections.

Key Differentiators

  • The network can be delivered over multiple connections (MPLS, broadband, LTE) to improve traffic delivery.
  • Dynamically directs traffic to the best accessible connection, and if the accessible connections show any transmission issues, it will apply remediation for jitter and packet loss according to policies to guarantee application performance.
  • For simplicity of management, cloud-based administration allows universal access across all gadget types.
  • The system will adapt quickly to changing needs, including adding cloud-based services, establishing new branches, and working remotely.
  • All traffic is routed dynamically for advanced application and data delivery.
  • When segments are bought online, they are connected to a focal orchestrator, and configurations are pushed from the orchestrator to the edge gadget.
  • Cisco Meraki SD-WAN

Cisco Meraki combined network security and SD-WAN into one appliance. By securely auto-provisioning IPsec VPN tunnels between sites, these MX appliances form a system for Cisco SD-WAN controlled by Meraki. To create center point-and-spoke or network VPN topologies, Meraki’s dashboard automatically sets up VPN routes, validation and encryption protocols, and key exchange between all Meraki MX appliances in an association.

Key Differentiators

It incorporates a leading-edge layer-7 firewall, Cisco Advanced Malware Protection (AMP), intrusion prevention, SSL decoding/assessment, data loss prevention (DLP), cloud access security broker (CASB), granular application control, and file type control.

The Virtual MX (vMX) offers the basic configuration advantages associated with automatic VPN site-to-site as presented by Meraki security appliances.

Easily connect branch sites using a physical MX appliance to resources in the open cloud environment with Auto VPN in two clicks.

Provide improved access to business-critical resources using SD-WAN across public cloud environments.

Dynamic Path Selection can be used to maintain an ideal path for traffic to ordinary servers in a data center behind a physical MX, or virtual services behind a virtual MX.
