In today’s fast-paced digital landscape, maintaining a dependable and resilient network is crucial for businesses of all sizes. Downtime and disruptions can result in lost opportunities, decreased productivity and disgruntled customers. 

Fortunately, groundbreaking technology has emerged to tackle these challenges head-on: Software-Defined Wide Area Networking (SD-WAN). 

This innovative IT solution offers a plethora of benefits that significantly enhance network availability and reliability, ensuring seamless connectivity even in the face of adversity. 

Understanding SD-WAN

SD-WAN is a modern networking technology designed to enhance the performance, flexibility and management of Wide Area Networks (WANs).  

In other words, SD-WAN is your network’s traffic police.  

With multiple lanes of network traffic, SD-WAN will utilize each lane, or Internet circuit, monitor congestion and security risks, and determine where the traffic is routed to give you the best experience.  

On top of that, SD-WAN creates an express lane for prioritized, mission-critical applications to increase uptime and network bandwidth, without sacrificing security and data privacy.  

This new approach to network connectivity provides: 

  • WAN optimization 
  • Lower operational costs 
  • Bandwidth efficiency 
  • Reliable cloud connectivity 
  • Improved resource usage for multisite deployments 

An enhanced approach is highly necessary to securely direct traffic from branch offices to trusted SaaS and cloud-based applications via the Internet while strictly complying with enterprise security requirements. 

The Importance of Network Reliability

The Internet has become a mission-critical, or business-critical, application. As more of our applications migrate to the cloud, the more mission-critical the Internet becomes. 

For example, seamless virtual meetings are vital for business success. Choppy audio, video disruptions and unreliable internet connections can lead to critical application loss. Network issues cause severe downtime, impacting productivity and reputation. 

The cloud connects to all parts of an organization, including: 

  • CRM systems 
  • Phone systems 
  • Office applications 
  • ERP systems 
  • And more! 

With SD-WAN constantly monitoring those Internet pipelines, it can prioritize the mission-critical traffic to enhance network performance and maintain network security. 

The Key Features of SD-WAN 

Automatic Failover: Reliability at Its Finest

One of the standout features of SD-WAN is its ability to provide automatic failover. Traditional networks are susceptible to single points of failure, leading to downtime and potential data loss.  

SD-WAN mitigates this risk by proactively monitoring the health of network connections. In the event of a link failure, SD-WAN swiftly redirects traffic to alternative pathways, ensuring uninterrupted connectivity.  

In other words, your network will be up constantly. 

Link Aggregation: Maximizing Bandwidth Utilization

In the era of bandwidth-hungry applications and cloud-based services, the need for increased network capacity is paramount. 

SD-WAN employs link aggregation, a process of combining multiple connections into a single logical link. This results in improved bandwidth management and optimizes network performance, reducing the risk of bottlenecks and latency issues. 

Load Balancing: Efficient Distribution of Traffic 

In a network infrastructure, traffic can be unpredictable and unevenly distributed. 

SD-WAN's intelligent load balancing feature dynamically assesses the available network paths and efficiently distributes traffic across multiple links. This ensures no single link is overwhelmed, maintaining optimal network performance and reducing the risk of congestion-related downtime. 

Like I said, traffic police! 

The Role of Managed IT Services

Managed IT Service Providers have embraced SD-WAN as a game-changing tool to deliver exceptional network availability and reliability to their clients, minimizing costly downtime.  

When a Managed IT Service Provider (MSP) assesses an organization's network for SD-WAN implementation, they consider several crucial factors to ensure successful deployment and optimal performance, such as: 

  • Network architecture 
  • Application requirements 
  • Bandwidth and traffic patterns 
  • Security needs 
  • Connectivity options 
  • Quality of Service (QoS) requirements 
  • Network management 
  • Budget and ROI 

By conducting a thorough assessment of these factors, the MSP can tailor the SD-WAN implementation to the organization's unique needs, ensuring a robust and reliable network infrastructure. 

Once SD-WAN is implemented, the MSP can provide proactive network monitoring, swift issue resolution and seamless connectivity.  

Power Your Success with SD-WAN 

In a hyper-connected world where digital operations drive success, network availability and reliability are no longer optional - they are essential. SD-WAN emerges as the ultimate solution.  

Managed IT Services help deliver exceptional network performance and network security through WAN optimization.
