What Makes MPLS and SD-WAN-Based Office Networks Different
Multi-protocol label switching (MPLS) or software-defined wide area network (SD-WAN)? Most business owners in Saskatoon who must choose between the two want to know which will work better for their office network. To make the right choice, you first need to understand their differences.
In short, MPLS is a dedicated circuit, while SD-WAN is a virtual connection that does not depend on physical links. Because of this, MPLS is better at preventing packet loss. The virtual overlay in SD-WAN, on the other hand, allows users to utilize additional network links such as LTE, broadband, and MPLS, offering more flexibility.
Compare Costs
Companies that use MPLS networks typically employ a hub-and-spoke model with separate MPLS connections to link their remote offices to the main data center. As a result, all data, processes, and even cloud-based services require routing back to the data center for processing and redistribution. This setup is often not cost-effective.
SD-WAN reduces costs by connecting multiple locations through private, distributed data exchanges and control points. This configuration allows users improved and more direct access to the cloud and networking services they require.
Issues with Security
The internal backbone of the service provider acts as a secure and managed link between the company’s data center and branch offices, a benefit well-known to companies using MPLS. Most public internet services do not offer this level of security.
However, it's important to note that MPLS does not inherently inspect the data it carries. A firewall must be installed at one end of the link to scrutinize all traffic for malware and other security threats.
Additionally, this is a challenge that most SD-WAN systems face, necessitating enhanced security measures. Integrating security tools post-deployment complicates the process.
To prevent these issues, skilled network installation service providers incorporate SD-WAN connectivity directly into a next-generation firewall (NGFW) device. Each connection, therefore, features dynamic, meshed virtual private network (VPN) capabilities to secure data in transit. Several security tools, including firewalls, antivirus software, intrusion prevention systems, web filtering, and anti-malware, are employed to thoroughly scrutinize data.
How the Network Operates
In terms of performance, MPLS offers a consistent and fixed bandwidth level, which is advantageous for businesses. However, today's network traffic has variable speed demands. Thus, when businesses opt for an MPLS solution, there may be periods when expensive bandwidth remains underused, and times when MPLS may strain network connectivity due to the ever-increasing volume of data transmitted through new apps and devices.
SD-WAN can identify the types of apps in use and adjust bandwidth accordingly. It also sets up multiple parallel links to facilitate load sharing. Another advantage is failover, which involves switching to an alternate link if one connection fails. This feature ensures that latency-sensitive applications continue to perform optimally.
When MPLS May Be Preferable to SD-WAN
There are instances where MPLS might be a more suitable choice than SD-WAN, despite being considered an older network protocol by many.
MPLS remains an effective method for establishing secure and isolated connections for apps, transactions, and data that need to be kept separate from public internet networks. It offers a high level of data security. Both MPLS and SD-WAN can also be used together to manage various online activities.
If you are undecided between SD-WAN and MPLS, do not hesitate to consult network service providers. They understand how to leverage each technology in different scenarios and can help you choose the best option for your digital-first office.
