In the intricate web of modern networking, ensuring Quality of Service (QoS) over the Internet can be a formidable challenge. Traditional networking tools fall short in this domain, leaving businesses grappling with bandwidth saturation, cyber threats, and the perennial struggle for seamless connectivity. An example where poor QoS has an impact is Voice over IP (VoIP). This article delves into the intricacies of QoS, explores its parameters, and unveils a solution in the form of Software-Defined Wide Area Network (SD-WAN).

The QoS Predicament: A Struggle with Legacy Networking Kit

Implementing QoS over the Internet with legacy networking equipment proves to be a futile endeavor. The inability to control packet transmission rates, coupled with the design of network protocols that aim to use all available bandwidth, results in a chaotic network environment. Cyber threats, such as Denial of Service (DoS) and Distributed Denial of Service (DDoS) attacks, further exacerbate the challenges.

Buying more bandwidth is a conventional but economically taxing solution, and applications rarely control data rates. The lack of visibility into the speed of available bandwidth complicates self-control mechanisms for applications. To achieve proper QoS for the Internet, every intermediate router must support a consistent QoS mechanism, posing financial and logistical hurdles which invariably are never implemented by any operator or ISP.

The Role of SD-WAN in Revolutionizing QoS

Enter SD-WAN, a transformative solution that revolutionizes QoS implementation. SD-WAN addresses the limitations of traditional networking by offering a unified, end-to-end solution for connectivity, application acceleration, and robust security measures.

Parameters of QoS and Their Significance:

  1. Bandwidth: Crucial for services like VoIP and video conferencing.

  2. Latency: Affects online games, VNC, SSH sessions, voice, and live video.

  3. Jitter: Variation in latency, particularly critical for live services like VoIP and video conferences.

  4. Fairness: Ensures equal distribution of resources among connections and services.

How No QoS Impacts Businesses: Without QoS, the Internet becomes susceptible to degradation through large file downloads, hindering critical business operations.

Implementing standalone QoS with SD-WAN:

SD-WAN Endpoint Strategies: Endpoints can implement QoS strategies by shaping their own transmission rates, mitigating part of the problem. Its only applied in the outbound direction!

Mitigating Last Mile Congestion: Utilizing an appropriate and more sophisticated SD-WAN architecture, such as the one from Fusion's SD-WAN, offers a better approach. By leveraging a hub-and-spoke model, control points at both ends of the last mile, with the hub located at the Internet Exchange peering point, enable bidirectional QoS. This innovative architecture ensures a consistent and enhanced user experience by monitoring and managing bandwidth in real-time. The user experience conundrum over the last mile is put to bed and solved. Outgoing and more significantly incoming transmission rates are managed over the last mile to a location where the impact of degradation is minimal.

Fusion's QoS is based on the industry's best implementation which is a Linux stalwart known as tc. You can even visualize it using Netdata. Its stable, is compatible with cloud services and is widely used! Probably the most widely used across all Internet connected devices.


Empowering Businesses with Seamless Connectivity Fusion Broadband South Africa's SD-WAN emerges as a beacon of hope in the complex landscape of QoS over the Internet. By transcending the limitations of legacy networking, Fusion's SD-WAN provides businesses with the tools needed to navigate the challenges of bandwidth, latency, jitter, and fairness. The implementation of QoS through SD-WAN not only safeguards businesses from cyber threats but also paves the way for a more resilient and efficient network infrastructure.

In the evolving digital era, businesses must embrace innovative solutions like Fusion's SD-WAN to ensure a seamless and optimal user experience over the Internet. The journey to robust QoS begins with the adoption of SD-WAN, heralding a new era of connectivity and operational efficiency.
