SD-WAN vs MPLS: Which Network Is Right for Your Business?
Reconsidering your network connectivity solutions? Reliable connectivity has become one of the most important foundations of today’s business. Whether you’re operating multiple offices, supporting remote employees, running cloud applications, or managing customer communications, your network plays a critical role in productivity and business continuity.
For many years, Multi-Protocol Label Switching (MPLS) was the preferred networking solution for businesses requiring secure, reliable connectivity between locations. Today, Software-Defined Wide Area Networking (SD-WAN) has emerged as a flexible, cloud-first alternative that is rapidly being adopted by organisations across Australia.
So, which solution is right for your business?
The answer depends on your applications, locations, security requirements, budget, and future growth plans. Understanding the differences between SD-WAN and MPLS is the first step towards making an informed decision.
What Is MPLS?
Multi-Protocol Label Switching (MPLS) is a private networking technology that securely connects multiple business sites over a telecommunications provider’s dedicated network.
Unlike traditional internet connections, MPLS routes traffic through predetermined network paths rather than the public internet. This provides businesses with:
- Reliable connectivity
- Predictable performance
- Low latency
- Quality of Service (QoS)
- Secure site-to-site communication
MPLS has long been the preferred solution for organisations running critical applications such as VoIP, ERP systems, and real-time business applications.
What Is SD-WAN?
Software-Defined Wide Area Networking (SD-WAN) is a networking solution that intelligently manages and optimises traffic across multiple internet connections. Rather than relying on a single private network, SD-WAN can combine and manage:
- Business fibre
- NBN Enterprise Ethernet
- 4G and 5G services
- Fixed wireless
- MPLS connections
- Broadband internet
Using software, SD-WAN automatically determines the most efficient path for different types of traffic, ensuring business-critical applications receive priority. This makes SD-WAN particularly well suited to businesses embracing cloud services and hybrid work environments.
SD-WAN vs MPLS: The Key Differences
Although both technologies connect multiple business locations, they operate in different ways.
| MPLS | SD-WAN |
| Uses a private carrier network | Uses multiple internet connections with intelligent traffic management |
| Fixed network paths | Dynamic traffic routing |
| Excellent for traditional business applications | Optimised for cloud applications and SaaS platforms |
| Highly predictable performance | Intelligent application-aware routing |
| Generally higher implementation costs | Often more cost-effective and scalable |
| Adding new sites can take weeks | New locations can often be deployed much faster |
| Limited flexibility | Highly flexible and cloud-ready |
Neither technology is inherently better, they simply suit different business requirements.
Benefits of MPLS
MPLS continues to offer significant advantages for businesses that require guaranteed network performance, such as:
Reliable Performance
– Traffic follows predetermined paths, providing consistent performance for critical business applications.
Low Latency
– Applications requiring real-time communication, such as voice and video, can benefit from reduced latency.
Strong Security
– Because MPLS operates over private carrier networks, data avoids travelling across the public internet.
Guaranteed Quality of Service
– Traffic can be prioritised to ensure important applications always receive sufficient bandwidth.
Benefits of SD-WAN
SD-WAN has become increasingly popular because it aligns with how today’s businesses operate, it offers:
Greater Flexibility
– Businesses can combine multiple connection types to improve their resilience and performance.
Cloud Optimisation
– SD-WAN is designed to support multiple cloud applications including:
- Microsoft 365
- Microsoft Teams
- Salesforce
- AWS
- Google Workspace
- Azure
Traffic is intelligently directed to optimise user experience.
Improved Business Continuity
– If one internet connection fails, SD-WAN can automatically reroute traffic through another available connection with minimal disruption.
Centralised Management
– Administrators can manage multiple locations through a single dashboard, simplifying your network administration.
Improved Scalability
– Adding new offices or remote locations is generally faster and easier than traditional MPLS deployments.
Which Businesses Should Consider MPLS?
MPLS remains an excellent solution for Australian organisations that require:
- Guaranteed network performance
- Highly predictable latency
- Private connectivity
- Mission-critical business applications
- Strict service level agreements (SLAs)
Industries commonly using MPLS include:
- Financial services
- Healthcare
- Government
- Large enterprise
- Manufacturing
- Logistics
Which Businesses Benefit Most from SD-WAN?
SD-WAN is particularly suited to organisations that rely heavily on cloud-based applications and flexible working environments. It is commonly adopted by:
- Professional services
- Multi-site retailers
- Healthcare providers
- Manufacturing businesses
- Education providers
- Hospitality groups
- Franchises
- Growing small and medium-sized businesses
Businesses with multiple offices often see significant improvements in flexibility and their network visibility after implementing SD-WAN.
Can Businesses Use Both?
Absolutely. Many organisations are now adopting a hybrid networking approach. For example:
- MPLS supports highly sensitive business applications
- SD-WAN manages cloud traffic and internet access
- Multiple internet services provide redundancy and resilience
This allows businesses to maximise performance while controlling costs.
How to Choose the Right Networking Solution for Your Business
Selecting the right network involves more than comparing technologies, important questions to consider include:
How many business locations do you have?
– Multi-site organisations often benefit from SD-WAN’s centralised management capabilities.
How important are cloud applications to your business?
– Businesses relying on applications like Microsoft 365, Teams, Salesforce, and other SaaS platforms often experience greater benefits from SD-WAN.
What level of uptime do you require?
– Organisations with critical operations may require redundant connections and business continuity planning.
What security requirements do you have?
– Highly regulated industries like health care and finance may have additional compliance and security requirements that influence network design.
What is your budget?
– While SD-WAN can often reduce ongoing connectivity costs, every business has different operational requirements.
A professional network audit can help determine the most appropriate solution.
